Veo Use

Veo Use

Use this skill to generate and edit videos using Google's Veo models (veo-3.1 and veo-2.0).

This skill uses portable Python scripts managed by uv.

Prerequisites

Ensure you have one of the following authentication methods configured in your environment:

1. API Key:

   • GOOGLE_API_KEY or GEMINI_API_KEY

2. Vertex AI:

   • GOOGLE_CLOUD_PROJECT
   • GOOGLE_CLOUD_LOCATION
   • GOOGLE_GENAI_USE_VERTEXAI=1

Usage

1. Text to Video

Generate a video purely from a text description.

uv run skills/veo-use/scripts/text_to_video.py "A cinematic drone shot of a futuristic city" --output city.mp4

2. Image to Video

Generate a video starting from a static image context.

uv run skills/veo-use/scripts/image_to_video.py "Zoom out from the flower" --image start.png --output flower.mp4

3. Reference to Video

Use specific asset images (subjects, products) to guide generation.

uv run skills/veo-use/scripts/reference_to_video.py "A man walking on the moon" --reference-image man.png --output moon_walk.mp4

4. Edit Video (Inpainting)

Modify existing videos using masks.

Modes:

• REMOVE: Remove dynamic object.
• REMOVE_STATIC: Remove static object (watermark).
• INSERT: Insert new object (requires --prompt).

uv run skills/veo-use/scripts/edit_video.py --video input.mp4 --mask mask.png --mode INSERT --prompt "A flying car" --output edited.mp4

5. Extend Video

Extend the duration of an existing video clip.

uv run skills/veo-use/scripts/extend_video.py --video clip.mp4 --prompt "The car flies away into the sunset" --duration 6 --output extended.mp4

Common Options

• --model: Default veo-3.1-generate-001.
• --resolution: 1080p (default), 720p, 4k.
• --aspect-ratio: 16:9 (default), 9:16.
• --duration: 6 (default), 4, 8.
