Video Generation: Create videos with Veo

Overview

Generate videos using Google's Veo models. Supports:

• Text-to-video generation (4-8 seconds)

• Image-to-video (animate a starting frame)

• Native audio generation with dialogue and sound effects (Veo 3.1)

Reference: https://ai.google.dev/gemini-api/docs/video

How to use

bash ${CLAUDE_PLUGIN_ROOT}/scripts/gemini.sh --model=veo-3.1-generate-preview "YOUR VIDEO DESCRIPTION"

Arguments:

• --model

• Required: Use a Veo model (see Models below)

• --file

• Optional: Starting frame image for image-to-video

• --aspect-ratio

• Optional: 16:9 (default) or 9:16

• --duration

• Optional: 4 , 6 , or 8 seconds (default: 8)

Examples:

Generate a video from text

npx -y superconductor-gemini-skills --model=veo-3.1-generate-preview "A serene mountain landscape at sunset, camera slowly panning right"

Generate with specific aspect ratio and duration

npx -y superconductor-gemini-skills --model=veo-3.1-generate-preview --aspect-ratio=9:16 --duration=4 "A person walking through a busy city street"

Include dialogue (Veo 3.1)

npx -y superconductor-gemini-skills --model=veo-3.1-generate-preview "Two friends at a coffee shop. One says "Did you hear the news?" The other replies "No, what happened?""

Animate an image

npx -y superconductor-gemini-skills --model=veo-3.1-generate-preview --file=landscape.jpg "Camera slowly zooms in on the mountain peak"

Fast generation (lower quality, quicker)

npx -y superconductor-gemini-skills --model=veo-3.1-fast-generate-preview "A cat playing with a ball of yarn"

Prompt tips

Effective prompts should include:

• Subject: What appears in the video

• Action: What the subject does

• Style: Creative direction (cinematic, documentary, etc.)

• Camera: Movement and positioning (pan, zoom, tracking shot)

• Audio (Veo 3.1): Dialogue in quotes, sound effect descriptions

Output

Generated videos are saved to the current directory as gemini-video-{timestamp}.mp4 .

Limitations

• Video length: 4-8 seconds

• Generation time: 11 seconds to 6 minutes

• Videos stored on server for 2 days

• All videos include SynthID watermarks
