Video Generation

Generate videos from text descriptions using Google's Veo model via the generate_video tool.

Setup

Enable video generation in Settings UI or set NOMOS_VIDEO_GENERATION=true
Get a Gemini API key from https://aistudio.google.com/apikey (same key used for image generation)
Set GEMINI_API_KEY in Settings or environment

Tool: `generate_video`

Parameters:

prompt (required) — Detailed description of the video to generate
output_path (optional) — File path to save the video (defaults to temp directory)
duration_seconds (optional) — Video duration in seconds (1-30)

Note: Video generation is a long-running operation. It typically takes 1-3 minutes to complete.

Writing Effective Video Prompts

Good video prompts describe motion and time, not just a static scene. Include:

Subject and action: What is happening, who/what is moving
Camera work: Pan, tilt, zoom, tracking shot, static, drone shot, handheld
Scene setting: Location, time of day, weather, environment
Style: Cinematic, documentary, slow motion, timelapse, animation
Mood and atmosphere: Lighting, color grading, emotional tone
Temporal flow: What happens first, then next

Prompt Examples

Simple:

A drone shot slowly flying over a misty mountain range at sunrise

Cinematic:

A slow-motion close-up of a coffee cup being filled with espresso, steam rising, warm golden light from a nearby window, shallow depth of field, cinematic color grading

Action:

A tracking shot following a cyclist riding through autumn leaves on a tree-lined path, golden hour lighting, leaves swirling in their wake

Abstract:

Flowing liquid mercury forming geometric shapes in zero gravity, reflecting prismatic light, smooth transitions between forms, dark background, studio lighting

Narrative:

A time-lapse of a flower blooming in a garden, starting from a tight bud to full bloom, morning dew evaporating, soft natural lighting, macro lens perspective

Camera Movement Keywords

Static: Fixed camera, no movement
Pan: Horizontal camera rotation (left/right)
Tilt: Vertical camera rotation (up/down)
Zoom: Moving closer or further (zoom in/out)
Tracking/dolly: Camera moves alongside the subject
Drone/aerial: Overhead or elevated perspective
Handheld: Slight natural camera shake
Orbit: Camera circles around the subject
Crane: Vertical camera movement (rising/lowering)

Style Keywords

Cinematic: Film-quality, 24fps feel, color graded
Documentary: Natural, observational
Slow motion: Time-stretched action
Timelapse: Compressed time
Hyperlapse: Moving timelapse
Animation: Animated/cartoon style
Vintage/retro: Film grain, muted colors
Noir: High contrast, dramatic shadows

Output

Videos are saved as MP4 (default) or WebM
Default save location is the system temp directory
Specify output_path to save to a specific location

Tips

Be specific about camera movement — it dramatically changes the result
Describe what changes over time, not just a static scene
Include lighting and atmosphere details for cinematic quality
Keep prompts focused on a single coherent scene
Shorter durations tend to produce higher quality results
