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.
