* **Brand storytelling**: Cinematic sequences that maintain visual identity throughout
* **UGC-style content**: Realistic dialogue-driven videos with natural sound design
* **Social video series**: Consistent characters across multiple episodes
* **Testimonial-style ads**: Authentic-feeling videos with scripted dialogue
### Weaknesses
* Premium pricing due to advanced features
* Longer generation times for complex multi-shot sequences
* Requires detailed prompting knowledge for best results
* Limited duration options

## How to use effectively
#### Model versions
This model is available in two versions:
* **Veo3.1**: Highest quality, best for complex prompts and multi-shot sequences. Premium pricing.
* **Veo3.1 Fast**: 2x cheaper, faster generations, suitable for simpler prompts. Still high quality for most use cases.
#### Prompting
Veo3.1 Prompting Formula
Veo3.1 performs best with structured prompts following this pattern:
**Cinematography + Subject + Action + Context + Style & Ambiance**
This formula gives you granular control over every aspect of generation:
**Cinematography**: Define camera work and shot composition
* Camera movement: dolly shot, tracking shot, crane shot, aerial view, slow pan, POV shot
* Composition: wide shot, close-up, extreme close-up, low angle, two-shot
* Lens & focus: shallow depth of field, wide-angle lens, soft focus, macro lens, deep focus
**Subject**: Identify the main character or focal point
* Be specific about appearance, clothing, and distinguishing features
**Action**: Describe what the subject is doing
* Use active verbs and specific movements
**Context**: Detail the environment and background elements
* Location, time of day, weather, surrounding objects
**Style & Ambiance**: Specify artistic direction and mood
* Visual style, lighting quality, color palette, era references
**Example Prompt**: "Close-up shot, a young chef in a white apron, carefully drizzling golden olive oil over a vibrant caprese salad, in a sunlit rustic kitchen with exposed brick walls and hanging copper pots. Natural morning light streams through a large window, creating soft shadows. Warm, inviting aesthetic with rich color saturation, shot on modern cinema camera."
Audio Direction
Control the soundstage with specific audio cues in your prompts:
**Dialogue**: Use quotation marks for specific speech
* Example: *A woman says, "We have to leave now."*
**Sound Effects (SFX)**: Describe sounds with clarity
* Example: *SFX: thunder cracks in the distance*
**Ambient Noise**: Define the background soundscape
* Example: *Ambient noise: the quiet hum of a starship bridge*
Audio is automatically generated based on visual content and your prompt specifications.
First and Last Frame Transitions
Create smooth transitions between two scenes:
1. Generate your starting frame using another image model
2. Generate a complementary ending frame with a different POV or angle
3. Use Veo3.1's First and Last Frame feature to create the transition video
4. Include dialogue or audio cues in your prompt
Example use case: Singer transitions from front-facing close-up to behind-the-shoulder stage view with lyrics as dialogue.
Timestamp Prompting (Advanced)
Create multi-shot sequences with precise timing within a single generation:
Format: `[HH:MM:SS-HH:MM:SS] Shot description with cinematography, action, emotion, and SFX`
Example:
```
[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.
[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.
```
This creates a cohesive multi-shot sequence in one generation with proper pacing and visual consistency.
Ingredients to Video (Multi-Shot Consistency)
Maintain character and style consistency across multiple shots:
1. Generate your "ingredients" using an image model: character portraits, locations, style references
2. Upload these ingredients as reference images to Veo3.1
3. Prompt for different shots using the same characters and settings
4. Veo3.1 maintains visual consistency across all generated shots
Example use case: Film noir detective scene with consistent character appearances across multiple camera angles.
#### Inputs
* **Text only**: For generating new videos from descriptions
* **Text + 1 Reference Image**: For image-to-video animation
* **Text + 2 Images used with First frame and End frame parameters**: For transition videos between scenes
* **Text + Multiple Reference Images used as first frame**: For ingredients-based sequences with consistent elements
