## Pick the right endpoint
Listed newest first. Both endpoints are Google Veo 3-1; pick by quality/latency trade-off.
**Veo 3-1 Extend** — `google-deepmind/veo-3-1/extend-video` *(default)*
> Continues an existing Veo clip with consistent motion, lighting, identity, and physics.
> Pick for: hero-quality extends, final-delivery cuts, chained narrative shots that need to look like one continuous take.
> Avoid for: cost-sensitive iteration — drop to **Veo 3-1 Fast Extend**.
**Veo 3-1 Fast Extend** — [`google-deepmind/veo-3-1/fast/extend-video`](https://www.runcomfy.com/models/google-deepmind/veo-3-1/fast/extend-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=video-extend)
> Faster Veo 3-1 extend at lower per-call cost.
> Pick for: iteration on extend compositions, multi-shot drafts.
> Avoid for: final delivery — use full **Veo 3-1 Extend**.
The agent picks one and supplies the source video URL + a continuation prompt.
