veo3-video-gen

Generate and stitch short videos via Google Veo 3.x using the Gemini API (google-genai). Use when you need to create video clips from prompts (ads, UGC-style clips, product demos) and want a reproducible CLI workflow (generate, poll, download MP4, optionally stitch multiple segments).

技能说明

Veo 3 Video Generation (Gemini API)

Use the bundled script to generate an MP4 from a text prompt.

Generate (text → video)

uv run {baseDir}/scripts/generate_video.py \
  --prompt "A close up of ..." \
  --filename "out.mp4" \
  --model "veo-3.1-generate-preview" \
  --aspect-ratio "9:16" \
  --poll-seconds 10

Generate a longer video by stitching segments

Veo commonly outputs ~8s clips per request. Use --segments to generate multiple clips and concatenate them with ffmpeg.

Important: This skill sends one prompt per segment (one Veo request per segment). Use --base-style to keep style consistent across segments.

uv run {baseDir}/scripts/generate_video.py \
  --prompt "Same scene, consistent style..." \
  --filename "out-24s.mp4" \
  --model "veo-3.1-generate-preview" \
  --aspect-ratio "9:16" \
  --segments 3 \
  --segment-style continuation

Options:

--base-style "...": prepended to every segment prompt (recommended).
--segment-prompt "..." (repeatable): provide one prompt per segment (overrides --prompt).
--segment-style continuation (default): appends continuity instructions per segment (only when using --prompt).
--segment-style same: uses the exact same prompt for each segment (only when using --prompt).
--use-last-frame: for segment >=2, extract previous segment last frame and pass it as lastFrame for continuity.
--emit-segment-media: print MEDIA: for each segment as it finishes (useful for progress).
--keep-segments: keep intermediate *.segXX.mp4 files.
--reference-image path.jpg (repeatable): guide generation with product/style references.

Requirements

GEMINI_API_KEY env var (or --api-key).
ffmpeg on PATH when using --segments > 1.

Troubleshooting

429/RESOURCE_EXHAUSTED: API key has no quota/billing for video.
503/UNAVAILABLE: model overloaded; retry later.

# Veo 3 Video Generation (Gemini API)

Use the bundled script to generate an MP4 from a text prompt.

## Generate (text → video)

```bash
uv run {baseDir}/scripts/generate_video.py \
  --prompt "A close up of ..." \

  --model "veo-3.1-generate-preview" \

## Generate a longer video by stitching segments

Veo commonly outputs ~8s clips per request. Use `--segments` to generate multiple clips and concatenate them with ffmpeg.

**Important:** This skill sends **one prompt per segment** (one Veo request per segment). Use `--base-style` to keep style consistent across segments.

```bash
uv run {baseDir}/scripts/generate_video.py \
  --prompt "Same scene, consistent style..." \
  --filename "out-24s.mp4" \
  --model "veo-3.1-generate-preview" \
  --aspect-ratio "9:16" \
  --segments 3 \
  --segment-style continuation
```

Options:
- `--base-style "..."`: prepended to every segment prompt (recommended).
- `--segment-prompt "..."` (repeatable): provide one prompt per segment (overrides `--prompt`).
- `--segment-style continuation` (default): appends continuity instructions per segment (only when using `--prompt`).
- `--segment-style same`: uses the exact same prompt for each segment (only when using `--prompt`).
- `--use-last-frame`: for segment >=2, extract previous segment last frame and pass it as `lastFrame` for continuity.
- `--emit-segment-media`: print `MEDIA:` for each segment as it finishes (useful for progress).
- `--keep-segments`: keep intermediate `*.segXX.mp4` files.
- `--reference-image path.jpg` (repeatable): guide generation with product/style references.

## Requirements

- `GEMINI_API_KEY` env var (or `--api-key`).
- `ffmpeg` on PATH when using `--segments > 1`.

## Troubleshooting

- 429/RESOURCE_EXHAUSTED: API key has no quota/billing for video.
- 503/UNAVAILABLE: model overloaded; retry later.
