; } ``` # 4. The Engine: Automated Billing with Stripe The Stripe plugin handles the complexity of creating customers, managing checkout, and listening for webhook events. You focus on your product. ### Trigger a Subscription From your pricing page, a client-side action creates a Checkout Session and redirects the user to Stripe. ```typescript // Your client-side action import { createAuthClient } from "better-auth/react"; const authClient = createAuthClient(); export async function startSubscription(plan: "basic" | "pro") { const { error } = await authClient.subscription.upgrade({ plan, successUrl: `${window.location.origin}/dashboard`, cancelUrl: `${window.location.origin}/pricing`, }); if (error) { // Handle error gracefully alert(error.message); } } ``` ### Handle with Webhooks Point your Stripe webhook to /api/auth/stripe. The plugin handles signature verification and updates your database automatically when a subscription is created or changed. Use the Stripe CLI for local testing: ```bash stripe listen --forward-to localhost:3000/api/auth/stripe ``` ### Manage Billing Redirect users to the Stripe Billing Portal to manage their subscriptions, payment methods, and invoices. The plugin provides a simple action to create a portal session. # Security: Non-Negotiable Defaults * **CSRF Protection:** Handled out of the box by Better Auth for all auth-related POST requests. * **Webhook Verification:** The Stripe plugin validates webhook signatures. Rejects any request that doesn't match. * **Secret Management:** Keep BETTER\_AUTH\_SECRET and STRIPE\_SECRET\_KEY server-side. Never expose them to the client. # Wrap Up This is a blueprint - A robust, scalable, and modern foundation for building a real SaaS business. It’s designed to give you, the builder, maximum control and velocity by automating the tedious and abstracting the complex. Stop wrestling with legacy auth providers and messy billing code. Build on a solid foundation. Expand. Enhance. Then execute.

This section covers the **frameworks, techniques, and curated prompts** that unlock its full potential. *** ### 1.1 The 5-Part Prompting Formula The most reliable structure for Nano Banana generation follows a five-part formula. Start with a **strong verb** that tells the model the primary operation, then layer in specifics. **Formula:** `[Subject] + [Action] + [Location/Context] + [Composition] + [Style]` > \[!EXAMPLE] > **Before:** "A fashion photo" > > **After:** "A striking fashion model wearing a tailored brown dress, sleek boots, and holding a structured handbag. Posing with a confident, statuesque stance, slightly turned. On a seamless, deep cherry red studio backdrop. Medium-full shot, center-framed. Fashion magazine style editorial, shot on medium-format analog film, pronounced grain, high saturation, cinematic lighting effect." > > *Source: Google Cloud Blog*
### 1.2 Pseudo-Code Prompting (Chase Jarvis Technique)
Most people prompt like they're describing a dream — wandering sentences that lead to drift. The professional alternative is **Pseudo-Code Prompting**: define variables as distinct assets, then instruct the model how to combine them.
**Why it works:** You separate *what* from *how*. When iterating, you only change one variable — the model understands everything else must remain constant.
**The Structure:**
```
[VARIABLES]
SUBJECT_A = "Professional female model, mid-30s, sharp features,
wearing a structured oversized beige blazer, silk texture."
LOCATION_B = "Brutalist architecture interior, concrete walls,
sharp geometric shadows."
LIGHTING_C = "High-contrast rim lighting, cool blue fill from
the left, warm key light from the right."
CAM_SETTINGS = "Phase One XF, 80mm lens, f/2.8, ISO 100,
sharp focus on eyes."
[EXECUTION]
Render SUBJECT_A standing in LOCATION_B. Apply LIGHTING_C to
emphasize the texture of the blazer. Use CAM_SETTINGS for
a hyper-realistic commercial fashion look.
```
> \[!TIP]
> Use the "Thinking" or "Reasoning" mode for complex physics-based lighting. Add `[REASONING: Calculate true light paths based on light source position]` to force physics validation.
### 1.3 JSON Structured Prompting
For complex compositions where you need precise control over multiple elements, use structured JSON. Nano Banana's reasoning engine recognizes this logic and applies it consistently.
> \[!EXAMPLE]
> **Before:** "A young woman taking a mirror selfie, 2000s aesthetic"
>
> **After:**
>
> ```json
> {
> "subject": {
> "description": "A young woman taking a mirror selfie with
> very long voluminous dark waves and soft wispy bangs",
> "age": "young adult",
> "expression": "confident and slightly playful",
> "hair": {
> "color": "dark",
> "style": "very long, voluminous waves with soft wispy bangs"
> },
> "clothing": {
> "top": {
> "type": "fitted cropped t-shirt",
> "color": "cream white",
> "details": "features a large cute anime-style cat face graphic"
> }
> }
> },
> "photography": {
> "camera_style": "early-2000s digital camera aesthetic",
> "lighting": "harsh super-flash with bright blown-out highlights",
> "angle": "mirror selfie",
> "texture": "subtle grain, retro highlights, V6 realism"
> },
> "background": {
> "setting": "nostalgic early-2000s bedroom",
> "elements": ["chunky wooden dresser", "CD player",
> "hanging beaded door curtain"]
> }
> }
> ```

### 1.4 Positive Framing & Negative Prompting
Nano Banana understands what you want *better* when you describe the positive outcome rather than the negative.
> \[!EXAMPLE]
> **Before:** "A street with no people, no cars, no modern buildings"
>
> **After:** "A desolate cobblestone street at dawn, bathed in warm golden light. The storefronts are shuttered. No people, no vehicles. Atmospheric fog lingers near the ground."
>
> **Before:** "Remove the red car"
>
> **After:** "Replace the red car with a gray van that matches the lighting and perspective of the street. The van should appear parked, stationary, blending seamlessly with the ambient shadows."

### 1.5 Lighting & Camera Controls
Nano Banana speaks the language of lenses and light. Use specific photographic and cinematic terminology to control depth, distortion, perspective, and mood.
#### 1.5.1 Photography Terminology
| Control Type | Example Prompt |
| -------------- | -------------------------------------------------------------------------------------------------------------------------- |
| **Wide Angle** | "Shot on Leica SL2 with a 24mm lens. Exaggerate foreground features. Vertical distortion on architectural elements." |
| **Portrait** | "Shot on Canon R5 with an 85mm f/1.2 lens. Extremely shallow depth of field. Bokeh should be creamy and circular." |
| **Macro** | "100mm Macro lens. 1:1 magnification. Focus stacking simulation for edge-to-edge sharpness on the product texture." |
| **Low Angle** | "Low angle shot, looking up at the subject against an overcast sky. Wide-angle perspective to emphasize height and drama." |
> \[!EXAMPLE]
> **Before:** "Close-up portrait"
>
> **After:** "Close-up portrait of a weathered sailor, shot on Fujifilm GFX 100 with a 110mm f/2 lens. The lens creates natural background compression. Skin texture must be visible — pores, fine lines, sun damage. Catchlights present in the eyes. Dramatic chiaroscuro lighting from a single window on the left."
>
> *Source: Chase Jarvis*
#### 1.5.2 Lighting Ratios
Nano Banana's reasoning engine calculates light bounces with surprising accuracy. Define the behavior of light explicitly.
| Lighting Style | Prompt Description |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Rembrandt** | "Classic Rembrandt lighting. Key light at 45 degrees elevation, 45 degrees horizontal. Triangle of light on the shadowed cheek. Deep shadow density ratio of 3:1." |
| **Commercial** | "High-key commercial lighting. Large softbox source overhead. White bounce cards filling shadows. Even, flattering illumination. Catchlights in both eyes." |
| **Chiaroscuro** | "Dramatic chiaroscuro. Single directional source from above-right. Harsh shadows, high contrast. Key-to-fill ratio of 8:1." |
| **Three-Point** | "Three-point lighting: key light at 45 degrees, fill at 90 degrees at 50% power, rim light behind subject at full power creating edge separation." |
> \[!EXAMPLE]
> **Before:** "Well-lit portrait"
>
> **After:** "Three-point studio lighting. Key light: 90cm octabank, camera left, 70% power, creating soft shadows on the right cheek. Fill light: 60cm softbox, camera right, 35% power, lifting shadows to a 2:1 ratio. Rim light: narrow strip light behind subject, full power, separating hair from background. Deep charcoal gray seamless backdrop."
>

#### 1.5.3 Film Stock & Color Grading
Specify film stock, color science, or grading styles to control the emotional texture of the output.
> \[!EXAMPLE]
> **Before:** "A nostalgic photo"
>
> **After:** "Kodak Portra 400 film aesthetic. Warm, nostalgic color science with slightly lifted blacks. The green channel pushed toward yellow. Skin tones with a peachy warmth. Subtle film grain, halation around highlights, soft contrast curve."
>
> **Before:** "Cinematic look"
>
> **After:** "Cinematic color grading with muted teal tones in shadows and warm orange in highlights. Teal shadows, orange highlights (the classic teal-orange grade). Desaturated blacks with crushed blacks in the background. Slight vignette."
>

### 1.6 Reference Stack Workflows
The 14-reference-image limit is Nano Banana's most powerful professional feature. Use it strategically for campaign-scale consistency.
> \[!NOTE]
> Nano Banana supports up to 14 reference images in a single prompt. Recommended slot allocation: **Slots 1-3** for character turnarounds, **Slots 4-5** for brand assets (logo, color palette), **Slots 6-10** for style and mood references.
#### 1.6.1 The 14-Slot Reference Stack
```
[SLOT 1-3] Character Turnaround: front view, 3/4 view, side view
[SLOT 4] Brand Logo: transparent PNG, primary color palette
[SLOT 5] Color Swatches: exact hex values for campaign colors
[SLOT 6-8] Lighting References: mood board images defining the light quality
[SLOT 9-10] Style References: photography style, texture direction
[SLOT 11-14] Environment/Prop References: setting details, key props
Prompt:
"Using the character defined in Slots 1-3, place them into the
location described in Slot 11. Apply the lighting quality from
Slot 6. Ensure the brand logo from Slot 4 is visible on the
clothing. Maintain facial structure from Slot 1 exactly. Use
the color grading from Slot 9."
```
#### 1.6.2 Weavy Pose-Change Technique
Using the **Weavy** node interface, you can decouple a subject's identity from their pose — transferring the geometry from one image to another.
> \[!TIP]
> Run the generation **3-4 times**. If anatomy breaks (fingers, knees), swap the pose reference for a clearer image.
**Inputs:**
* **Top Node (Pose):** A reference image with the desired geometry — stock photo, sketch, or 3D block-out
* **Bottom Node (Subject):** Your target subject with the appearance you need to preserve
**The Pose-Transfer Prompt:**
```text
[@img1 is the pose reference]
[@img2 is the character reference]
First, examine img1 and extract the subject's pose, including
the position of all limbs, torso angle, and head orientation.
The objective is to transfer the subject's pose from img1 to img2.
Create an image of the content as shown in img2, but with the
main character of img2 posed in the same way as the character
of img1.
Keep everything else about img2 the same — medium, color,
saturation, lighting quality, background.
Don't change the background or contents of img2. Only transfer
the pose from img1's subject to img2's subject.
```
**Output:** The subject from img2 rendered in the exact pose from img1.
> \[!NOTE]
> This technique works with sketches and 3D block-outs as the pose reference — not just photographs. Concept artists use this to turn napkin sketches into photorealistic assets.
#### 1.6.3 Weavy Style-Cloning Technique
Apply the complete *aesthetic* of one image to the *subject* of another — without blending the content.
> \[!NOTE]
> The model doesn't just slap a filter on. It re-renders the subject from the ground up using the physics of the style reference.
**Inputs:**
* **Style Reference (img1):** The "vibe" — defines lighting, texture, color palette, rendering technique
* **Content Reference (img2):** The "subject" — the person, product, or scene you need
**The Style-Clone Prompt:**
```text
Create an image of the content as shown in [@img2] but with the
same medium, color palette, mood, rendering technique, saturation
level, textures, and overall style of [@img1].
Extract ONLY the aesthetic qualities from img1 — do not include
any objects, subjects, or compositions from img1.
Apply the extracted style to img2's subject while preserving
img2's subject identity and composition.
```
**Output:** The subject from img2 rendered with the lighting, texture, and color science of img1.
> \[!EXAMPLE]
> Style Reference: A glowing, subsurface-scattering orange illustration of cats on a blue background.
> Content Reference: A standard photograph of a king cobra.
> Result: The cobra re-rendered with the translucent orange glow and lighting physics of the cat illustration — without becoming a cat.
***
### 1.7 Text Rendering & Typography
Nano Banana is the first AI image model with **reliable typography** — rendering sharp, legible text on posters, packaging, and product mockups. It supports multilingual text in 10+ languages.
> \[!TIP]
> **Text-first hack:** When generating text-heavy images, first converse with the model to generate the text concepts, then request the final image with that text embedded. This ensures the model gets the text right before worrying about composition.
**Rules for text rendering:**
| Rule | Example |
| ---------------------------- | -------------------------------------------------------------- |
| Use quotes around text | `"CREATIVE FUTURE"` in bold white sans-serif (Helvetica style) |
| Describe the font explicitly | "Century Gothic 12px font" or "flowing Brush Script" |
| Specify placement | "Title text at top, subtitle below, 2/3 text area" |
| Define layering | "Text acts as a cut-out window over the subject" |
> \[!EXAMPLE]
> **Before:** "A poster that says Creative Future"
>
> **After:** "A typographic poster with a solid black background. The words 'CREATIVE FUTURE' in bold white Helvetica Neue font, filling the center of the frame. The text acts as a cut-out window. A photograph of a misty mountain landscape is visible ONLY inside the letterforms, with soft bokeh in the background."

***
### 1.8 Real-Time Web Search Integration
Nano Banana 2 is powered by real-time information from web search. Instead of describing a fictional scene, instruct the model to retrieve current data and visualize it.
**The Formula:** `[Search/Source Request] + [Analytical Task] + [Visual Translation]`
> \[!EXAMPLE]
> **Before:** "The weather in San Francisco today"
>
> **After:**
>
> ```
> Search for current weather conditions, date, and time in San Francisco.
> Analytically, use this data to modify the scene: if it's raining,
> render the city with overcast skies and wet reflective streets.
> If it's sunny, render warm golden light washing over the buildings.
> Visualize this as a miniature city-in-a-cup concept embedded within
> a realistic, modern smartphone UI. The miniature city should reflect
> the actual current weather of San Francisco.
> ```

## Part 2: Music & Audio — Lyria
Lyria generates high-fidelity music and audio from text prompts and images. Built for creators who need **finished tracks** — not loops — Lyria gives you control over every dimension of a musical arrangement.
***
### 2.1 Prompting Architecture
Lyria prompting follows a layered structure. Each layer builds on the last: **Genre** establishes the foundation, **Tempo** sets the pace, **Instruments** fill the arrangement, **Dynamics** shape the flow, and **Vocals** carry the melody.
> \[!NOTE]
> Lyria supports **image-to-music**: upload any image and describe its mood to generate a matching soundtrack. Think about the subject, location, lighting, and atmosphere — Lyria interprets these visual cues musically.
#### 2.1.1 Genre & Era Control
Define the primary genre and optionally blend eras or styles.
> \[!EXAMPLE]
> **Before:** "A rock song"
>
> **After:** "1980s arena rock anthem. Heavy kick drum with double-pedal speed. Thick, gated-reverb snare cracking on beats 2 and 4. Distorted power chords in drop-D tuning. Emotive male tenor lead vocal with long sustained notes. Analog synthesizer pads in the background. Stadium reverb on the entire mix."
>
> *Source: DeepMind Lyria Prompt Guide*
**Genre Blending Examples:**
| Prompt | Result |
| ---------------------------------------------- | ------------------------------------------------------------------------------------ |
| "K-pop with a Motown edge" | Contemporary K-pop production values with classic soul vocal phrasing and brass hits |
| "Classical violins merged into a funk track" | Funk rhythm section with orchestral string arrangements overlaid |
| "Early 90s hip-hop with 808s and jazz samples" | Boom-bap drums, warm vinyl texture, jazz piano loops |
#### 2.1.2 Tempo Specification
Specify tempo directly (BPM) or indirectly (descriptive terms).
> \[!EXAMPLE]
> **Before:** "A fast song"
>
> **After:** "170 BPM drum and bass track. Rapid-fire hi-hat pattern at 16th notes. Fast-attack synthesizers. Energetic, urgent atmosphere."
>
> **Before:** "A slow song"
>
> **After:** "62 BPM slow soul ballad. Spacious drums with long decays. Relaxed tempo that allows each note to breathe."
>
> *Source: DeepMind Lyria Prompt Guide*
#### 2.1.3 Instrument Selection
Add specific instruments to shape the sonic character. If you don't specify, Lyria auto-selects instruments to suit the genre.
> \[!EXAMPLE]
> **Before:** "A jazz song"
>
> **After:** "Quintessential 1970s Motown soul. Lush, orchestral R\&B production. Warm bassline with melodic fills, locked into a steady drum groove with crisp snare and tambourine. Vintage organ harmonic bed. Three-piece brass section. Gritty, gospel-tinged male tenor lead vocal."
>
> *Source: DeepMind Lyria Prompt Guide*
| Instrument Control | Example |
| ------------------------------- | -------------------------------------------------------------------------------------------------------------- |
| **Add unexpected instruments** | "1990s R\&B with 80s synth" — adds analog synth textures to contemporary production |
| **Specify instrument behavior** | "Clean funk-style guitar rhythm, staccato chord stabs on the upbeat, warm wah-wah pedal swells, no distortion" |
| **Layer textures** | "Dense orchestral arrangement: string quartet, brass quintet, harp, tubular bells" |
#### 2.1.4 Dynamics & Arrangement
Define how music flows between sections — builds, drops, instrumental breaks, and dynamic swells.
> \[!EXAMPLE]
> **Before:** "A song with a loud part"
>
> **After:** "Wistful and airy. Soft, breathy female vocals with intimacy. The track builds slowly from a quiet piano intro into an explosive chorus at 1:30, with full drum kit, swelling strings, and layered backing vocals. After the chorus, it returns to the quiet piano arrangement with only vocals and soft synth pads."
>
> **Before:** "A song with background music"
>
> **After:** "Nocturnal aesthetic with cinematic forward motion. The track opens with ambient synth pads for 8 bars, then introduces a driving 16th-note analog synthesizer bass arpeggio. Percussion anchored by a powerful snare with 1980s gated reverb. Swelling cinematic pads build throughout. Male vocalist with soaring vocal lines enters at bar 16."

### 2.3 Image-to-Music Prompts
Upload any image to generate music that matches its mood. Think about three dimensions:
| Image Dimension | What to Describe | Musical Translation |
| --------------- | ------------------------------------ | --------------------------------------- |
| **Subject** | Who or what is the focus? | Genre, vocal gender, energy level |
| **Location** | Indoor/outdoor, city/nature, setting | Instrumentation, ambient sounds, tempo |
| **Atmosphere** | Happy, sad, tense, calm | Key, dynamics, tempo, chord progression |
> \[!EXAMPLE]
> **Image:** A proud-looking ginger cat sitting on a blanket draped over a cozy armchair. Soft light streams through a window, illuminating a coffee table with a cup and several stacked books. The cat's eyes are semi-closed — relaxed and sleepy.
>
> **Prompt:** "A lazy Sunday afternoon. Relaxed acoustic guitar strumming a fingerpicked pattern. Soft jazz piano chords in the background. The sound of a gentle rain on glass. Warm, nostalgic, peaceful. No vocals — pure instrumental atmosphere."
>

> This is a massive, anthemic Alternative Rock chorus in the style
> of Post-Grunge and Arena Rock. The foundation is a thunderous,
> powerful drum kit: a heavy kick drum hits while a thick,
> gated-reverb snare cracks on beats 2 and 4. A driving, melodic
> bass line propels the harmony forward, acting as a crucial melodic
> anchor.
>
> Layered electric guitars play palm-muted power chords with
> aggressive distortion. A lead guitar soars with a sustained
> pentatonic solo over the final 8 bars. The mix is thick and dense,
> with reverbs reaching 2-3 seconds on the drums.
>
> Floating powerfully over this dense instrumental wall is an emotive
> male tenor lead vocal, belting at full chest voice. Backing vocals
> harmonize in thirds. The chorus ends with a dramatic drum fill.
>
> Tempo: 128 BPM. Key: E minor.

#### 2.4.2 Bossa Nova Sunset
> \[!EXAMPLE]
>
> ```text
> An intimate, sophisticated Brazilian Bossa Nova track evoking the
> quiet atmosphere of a Rio beach at sunset. The tempo is a gentle
> 78 BPM. A nylon-string acoustic guitar plays the characteristic
> syncopated bossa nova rhythm — staccato chords on beats 2 and 4.
> A upright bass walks a relaxed melodic line.
>
> Gentle female vocals in Portuguese, breathy and intimate,
> with natural room ambience. The melody floats above the
> arrangement with subtle reverb. Soft shakers and a nylon guitar
> provide the rhythmic pulse. Gentle wave sounds blend into the
> mix as ambient texture.
>
> The arrangement is sparse — only guitar, bass, vocals, and subtle
> percussion. Warm, romantic, nostalgic.
> ```
>
> *Source: DeepMind Lyria Prompt Guide*
#### 2.4.3 Electronic Dance Floor
> \[!EXAMPLE]
>
> ```text
> Driving electronic dance music at 128 BPM. Four-on-the-floor
> kick drum with crisp transient attack. Layered hi-hats — closed
> on the 8th notes, open on the off-beats. Sidechained synth
> pads pumping in sync with the kick.
>
> A catchy melodic hook played on a warm analog supersaw
> synthesizer. Filter sweeps automate on every 8 bars. The bass
> is a thick sawtooth wave with moderate compression.
>
> Breakdown at 1:30: all elements drop except a filtered
> arpeggiated synth and single kick. Build-up reintroduces
> elements one by one. Full release at 2:00 with all elements
> at maximum volume. No vocals — pure instrumental energy.
> ```
>
> *Source: DeepMind Lyria Prompt Guide*
#### 2.4.4 Lo-Fi Hip-Hop Study Session
> \[!EXAMPLE]
>
> ```text
> A lo-fi hip-hop instrumental for studying. 85 BPM. Vinyl-warmed
> sampled drums with a heavily compressed kick and snare. The hi-hat
> pattern is swung slightly. A looped jazz piano sample plays a
> minor-key chord progression with natural reverb decay. A warm
> vinyl crackle sits at -24 dB in the background.
>
> A double bass plays a walking line that steps through the chord
> changes. The entire sample is processed through a low-pass filter
> that opens slightly during the chorus section. The mix is warm
> and slightly muddy — intentionally lo-fi. No vocals.
>
> Total runtime: 3 minutes, seamless loop.
> ```
>
> *Source: DeepMind Lyria Prompt Guide*
#### 2.4.5 Celtic Folk Ballad
> \[!EXAMPLE]
>
> ```text
> A Celtic folk ballad. Solo acoustic guitar in DADGAD tuning,
> fingerpicked in a traditional Celtic style. The melody is
> played on a tin whistle with natural vibrato. Occasional
> violin (fiddle) enters during the chorus, playing a mournful
> melody in A minor.
>
> A bodhran drum provides a steady pulse. Male vocalist sings
> in a traditional Irish folk style — slight nasality, strong
> projection, no vibrato. The lyrics tell a story of a sailor
> lost at sea.
>
> The arrangement grows organically: guitar solo intro,
> whistle joins at verse 2, full ensemble by the final chorus.
> Gentle room reverb. Recorded to sound like a live pub session.
> ```

The Veo 3.1 prompting formula mirrors the image formula but adds temporal and audio dimensions.
**Formula:** `[Cinematography] + [Subject] + [Action] + [Context] + [Style & Ambiance] + [Audio]`
> \[!EXAMPLE]
> **Before:** "A person working in an office"
>
> **After:** "Medium shot, a tired corporate worker rubbing his temples in exhaustion, in front of a bulky 1980s computer in a cluttered office late at night. The scene is lit by harsh fluorescent overhead lights and the green glow of the monochrome monitor. Retro aesthetic, shot as if on 1980s color film, slightly grainy. Ambient: the hum of old CRT monitors and the click of a mechanical keyboard."
>
> *Source: Google Cloud Blog*
***
### 3.3 Camera Movement Language
The `[Cinematography]` element is the most powerful tool for conveying tone and emotion. Use specific terms from professional filmmaking.
#### Camera Movement Reference Table
| Movement | Description | Prompt Example |

| **Dolly shot** | Camera moves toward or away from subject | "Slow dolly in toward the character's face, revealing their expression" |
| **Tracking shot** | Camera follows subject horizontally | "Tracking shot following the explorer as she steps into the clearing" |
| **Crane shot** | Camera moves up/down on a crane | "Crane shot starting low, ascending high, revealing the vast canyon" |
| **Aerial view** | Drone-style overhead shot | "Aerial view from 200 meters, slowly orbiting the castle" |
| **Slow pan** | Horizontal rotation | "Slow pan left to reveal the city skyline emerging from fog" |
| **POV shot** | First-person perspective | "POV shot from behind the singer, looking out at a cheering crowd" |
| **Dutch angle** | Tilted frame for tension | "Dutch angle, tilted 15 degrees, to convey disorientation" |
> \[!EXAMPLE]
> **Before:** "Video of a canyon"
>
> **After:** "Crane shot starting low on a lone hiker and ascending high above, revealing they are standing on the edge of a colossal, mist-filled canyon at sunrise, epic fantasy style, awe-inspiring, soft morning light."
>
> *Source: Google Cloud Blog*
#### Composition & Lens Controls

### 3.4 Sound Design Controls
Veo 3.1 generates complete, synchronized soundtracks based on text instructions.
| Audio Type | Syntax | Example |
| ----------------------- | -------------------------- | -------------------------------------------------------------------- |
| **Dialogue** | Quotation marks for speech | 'A woman says, "We have to leave now."' |
| **Sound Effects (SFX)** | Describe sounds precisely | "SFX: thunder cracks in the distance, followed by heavy rain" |
| **Ambient Noise** | Define the soundscape | "Ambient: the quiet hum of a starship bridge, distant console beeps" |
| **Music** | Describe the score | "Swell to a cinematic orchestral score with rising strings" |
> \[!EXAMPLE]
> **Before:** "Add some sound effects"
>
> **After:**
>
> ```
> [00:00-00:02] Medium shot of a woman entering a dark forest.
> SFX: crunching dry leaves underfoot, wind rustling through branches.
> Ambient: distant owl calls, the sound of the forest settling for night.
>
> [00:02-00:04] Close-up of the woman's face, eyes widening in fear.
> SFX: a sudden snap of a twig nearby. Heartbeat sound effect begins.
>
> [00:04-00:06] Wide shot revealing what she sees: ancient stone ruins.

>
> **After:**
>
> * "A desolate landscape with no buildings, no roads, no vehicles, no modern infrastructure — only wilderness"
> * "A crowd scene with no blurred faces, no duplicate characters, no distorted hands"
> * "An underwater scene with no visible camera equipment, no bubbles from artificial sources, no anachronistic objects"
> \[!NOTE]
> For video, negative prompting is especially useful for: **motion artifacts** ("no jittering, no motion blur on static objects"), **continuity errors** ("the time of day remains consistent throughout"), and **visual noise** ("no flicker, no frame drops").
***
### 3.6 Advanced Creative Workflows
#### 3.6.1 Workflow: First and Last Frame Transitions
Create controlled camera movements or transformations between two distinct images using the **First/Last Frame** feature.
**Step 1 — Generate the starting frame with Nano Banana:**
```
Medium shot of a female pop star singing passionately into a vintage
microphone. She is on a dark stage, lit by a single, dramatic
spotlight from the front. She has her eyes closed, capturing an
emotional moment. Photorealistic, cinematic, shot on medium-format
camera, 85mm lens, shallow depth of field.
```
**Step 2 — Generate the ending frame with Nano Banana:**
```
POV shot from behind the singer on stage, looking out at a large,
cheering crowd. The stage lights are bright, creating lens flare.
You can see the back of the singer's head and shoulders in the
foreground. The audience is a sea of lights and silhouettes.
Energetic atmosphere. Photorealistic, cinematic.
```
**Step 3 — Animate with Veo 3.1:**
```
The camera performs a smooth 180-degree arc shot, starting with
the front-facing view of the singer and circling around her to
end on the POV shot from behind her on stage. The
singer sings "when you look me in the eyes, I can see a million
stars." SFX: crowd cheering, stage lights humming. Music: swelling
arena rock anthem.
```
> \[!TIP]
> The transition prompt should describe the *camera movement* and *what happens between* the two frames, not just repeat the images.
#### 3.6.2 Workflow: Ingredients to Video (Character Consistency)
Generate multi-shot scenes with consistent characters using the **Ingredients to Video** feature with up to 4 reference images.
**Step 1 — Generate your ingredients with Nano Banana:**
Create reference images for each character and the setting (up to 4 total).
**Step 2 — Compose the scene:**
```
Using the provided images for the detective, the woman, and the
office setting, create a medium shot of the detective behind his
desk. He looks up at the woman and says in a weary voice,
"Of all the offices in this town, you had to walk into mine."
SFX: the creak of an old office chair, rain on glass outside.
Ambient: the muffled sound of city traffic, distant thunder.
```
```
Using the provided images for the detective, the woman, and the
office setting, create a shot focusing on the woman. A slight,
mysterious smile plays on her lips as she replies, "You were
highly recommended." Camera slowly dollies toward her face.
Lighting: a desk lamp creates a pool of warm light, the rest
of the office fades into shadow.
```
> \[!NOTE]
> The **Ingredients to Video** feature now supports **audio generation** alongside the consistent character visuals. Each shot can have its own dialogue, SFX, and ambient audio.
#### 3.6.3 Workflow: Timestamp Prompting
Direct a complete multi-shot sequence with precise cinematic pacing — all within a single generation.
> \[!EXAMPLE]
> **Before:** Single paragraph prompt
>
> **After:**
>
> ```
> [00:00-00:02] Medium shot from behind a young female explorer
> with a leather satchel and messy brown hair in a ponytail, as she
> pushes aside a large jungle vine to reveal a hidden path.
> Camera: slow dolly forward.
>
> [00:02-00:04] Reverse shot of the explorer's freckled face,
> her expression filled with awe as she gazes upon ancient,
> moss-covered ruins in the background.
> SFX: The rustle of dense leaves, distant exotic bird calls.
>
> [00:04-00:06] Tracking shot following the explorer as she
> steps into the clearing and runs her hand over the intricate
> carvings on a crumbling stone wall. Emotion: Wonder and reverence.
>
> [00:06-00:08] Wide, high-angle crane shot, revealing the
> lone explorer standing small in the center of the vast,
> forgotten temple complex, half-swallowed by the jungle.
> SFX: A swelling, gentle orchestral score begins to play.
> Ambient: the sound of wind through ancient stone corridors.
> ```

## Part 4: Cross-Modal Production Workflows
The Gemini 3 family of models is designed to work as an **integrated production pipeline**. Here's how to connect them.
***
### 4.1 Nano Banana to Veo 3.1 — Keyframe Workflow
The most powerful video production workflow starts with **Nano Banana** generating a storyboard of keyframes, then **Veo 3.1** animating between them.
**Step 1:** Generate your keyframes with Nano Banana Pro (use the timestamp formula from Section 3.6.3).
**Step 2:** Load the start and end frames into Veo 3.1's **First/Last Frame** feature.
**Step 3:** Write a Veo 3.1 prompt that describes the camera movement and audio between the two frames.
**Step 4:** Add Lyria-generated music to score the final video.
***
### 4.2 Nano Banana to Lyria — Image-to-Music
Upload any Nano Banana-generated image to Lyria and describe its mood for a matching soundtrack.
> \[!EXAMPLE]
> **Nano Banana generates:** A misty mountain landscape at dawn, a lone hiker silhouetted against an orange sky.
>
> **Lyria prompt:** "A cinematic ambient soundtrack for a mountain landscape. Solo acoustic guitar playing a contemplative fingerpicked pattern. The sound of wind through pine trees. A single bird call in the distance. No vocals. Expansive, peaceful, meditative. 70 BPM."
>
> *Source: DeepMind Lyria Prompt Guide*
***
### 4.3 Veo 3.1 + Lyria — Full Production Pipeline
For complete productions, use all three models in sequence:
1. **Nano Banana** generates concept art and keyframes
2. **Veo 3.1** animates the keyframes with synchronous audio
3. **Lyria** generates a custom score that layers with or replaces the Veo 3.1 audio
> \[!TIP]
> Use Lyria's stem controls to layer music *under* Veo 3.1's dialogue and SFX. Prompt Lyria with: "Background instrumental only, designed to sit beneath dialogue and sound effects. Tempo: 95 BPM, unobtrusive acoustic arrangement."
***

***
## Conclusion
With the Gemini 3 stack, **text, image, audio, and video** come from one call — no longer separate disciplines but a unified creative language.
The key principles that run across all three modalities:
* **Be specific.** Concrete details outperform vague descriptions in every model.
* **Start with a verb.** Tell the model the primary operation before describing the content.
* **Use structured formats.** Pseudo-code, JSON, timestamp notation — structure gives the model clear constraints.
* **Reference stacks are your power tool.** Up to 14 images for Nano Banana, 4 for Veo 3.1. Use them.
* **Iterate.** Run generations 3-4 times. The first output is rarely the best — refinement is part of the creative process.
* **Combine modalities.** Nano Banana keyframes + Veo 3.1 animation + Lyria scoring = professional-grade productions.

You don't have to rent AI by the call. This private AI stack runs language models with the incredibly efficient llama.cpp engine and build automated, agentic systems—all on your own hardware, with your data kept private.
No API fees. No rate limits. Just speed and safety.
# Why The Private AI Stack
* **Privacy & Control:** Your data, prompts, and models never leave your machine. This is non-negotiable for serious work.
* **Zero API Costs:** Experiment, iterate, and run massive workloads without worrying about a bill. The only cost is your hardware.
* **Performance & Efficiency:** llama.cpp is the gold standard for running LLMs on consumer hardware. Get fast inference speed on CPU, and more with a GPU.
* **Integrated Automation:** With N8N built-in, you can connect your private LLM to any app or API, creating powerful, automated agents that *do things*.
* **Simple Setup:** Forget configuration hell. This is a one-command deployment.
# Quick Start: From Zero to Private AI in 2 Minutes
This stack is engineered for builders who value their time. If you have Docker, you're ready.
## Prerequisites
* Docker and Docker Compose installed.
* Git installed.
### One-Command Deployment
Open your terminal and run:
1. **Clone the repository:**
```bash
git clone https://github.com/pantaleone-ai/private-ai-stack.git
```
2. **Navigate into the directory:**
```bash
cd private-ai-stack
```
3. **Launch the stack:**
```bash
docker-compose up -d
```
That's it. The stack is running on your machine.
* **Open WebUI (Your private ChatGPT):** `http://localhost:8080`
* **N8N (Your automation engine):** `http://localhost:5678`
The first time you run it, the stack will download the default model (Phi-3-mini), which may take a few minutes.
# The Core Components:
This is a curated foundation for building intelligent systems.
* **Llama.cpp:** The engine. A high-performance inference server that runs quantized GGUF models with maximum efficiency. It's the brains and the muscle of the operation.
* **Open WebUI:** The interface. A sleek, ChatGPT-like UI for interacting with your local models served by llama.cpp. Perfect for testing, RAG, and daily use.
* **N8N:** The automation layer. This is where the magic happens. Connect your private LLM to the real world to build agentic workflows, automate processes, and create systems that execute tasks.
# How to Extend and Expand:
Here\’s how you start building on top.
* **Load Different Models:** The stack starts with Phi-3-mini. Want to run a Llama 3 or Mistral model? Find a GGUF version on Hugging Face, then update the `LLM_MODEL_FILE` variable in your `.env` file and restart the stack.
```
# .env file - Find GGUF models from creators like "TheBloke"
LLM_MODEL_FILE=Llama-3-8B-Instruct.Q4_K_M.gguf
```
* **Build Your First Agentic Workflow:** Use N8N to create a workflow. Pull data from an API, have your local llama.cpp model process it, and then post the result to Slack or a database. This is the first step toward true automation.
* **Integrate a Vector Database:** Add another Docker container for a vector DB like Chroma or Weaviate. Use N8N and llama.cpp to build a private RAG system that can answer questions about your own documents.
* **Scale Your Hardware:** Running this on a laptop is great for development. When you're ready, deploy the same docker-compose.yml on a dedicated server with a powerful GPU. llama.cpp will automatically leverage it to unlock incredible speed and performance.
# Conclusion
This stack gives you the foundation to create, automate, and innovate on your own terms, powered by the lean and powerful llama.cpp engine. The tools are ready, the setup is simple, even for non developers.
Clone the repo, launch the stack, and start building something great.

# The v0 System Prompt
What Vercel's v0 prompt reveals about building AI tools.
# Deconstructing the v0 System Prompt: A Builder's Analysis
Vercel’s [v0](https://v0.dev/) is one of the most sophisticated **AI assistants** ever built for developers. Its system prompt is a masterclass in engineering a precise, high-quality tool. As builders, we should analyze this blueprint not just to admire it, but to understand its strengths and its deliberate limitations. This deconstruction is for those who want to build the next generation of **AI developer tools**.
## Key Strengths of the v0 Architecture
The v0 prompt demonstrates a highly effective, structured approach to building a specialized **AI agent**.
* **Enforced Modernity**: The prompt doesn't just suggest best practices like using Next.js 15; it enforces them. This ensures every output is built on a modern foundation.
* **Interactive Sandbox**: Using MDX to render live React components turns static code into a testable page, which is a huge boost for **developer productivity**.
* **Automated Scaffolding**: v0 is engineered to generate entire deployable Next.js applications, automating the tedious boilerplate phase of development.
* **Quality by Default**: A deep focus on accessibility and the ability to generate rich media like Mermaid diagrams are baked into its core instructions.
* **Engineered Reliability**: By including strict content filters and requiring citations, Vercel has built an **AI tool** with consistent output.
## The Walls of the Garden: Where Flexibility is Sacrificed
The prompt's precision is also its biggest constraint. It's a system designed for a flawless experience, but only within a predefined ecosystem.
* **The Next.js Prison**: The system is hard-coded for Next.js. If you're a builder working with SvelteKit or Vue, v0 is not for you. This is a deliberate architectural choice.
* **The Tyranny of the Default Stack**: The prompt mandates Tailwind CSS and Lucide React icons. This isn't a lack of options; it's a strategy to enforce a consistent, curated experience at the cost of creative freedom.
* **Limited Adaptability**: The inability for a user to define custom environment variables keeps the AI in a sterile sandbox, disconnected from the needs of many real-world applications.
These are not bugs to be fixed; they are features of a walled-garden strategy.
