video_url 400 on Sume: edit is supported only by Omni Flash 1.1
A video_url on any other model returns 400 on the Sume Video Router. Which models take a source video, and how to pick one for your edit.
The error says video_url (edit) is supported only by model gemini-omni-flash-1.1. It means you sent a prompt-driven edit to a model that has no edit mode. On the Sume Video Router, only gemini-omni-flash-1.1 rewrites a clip from a prompt. Other video-in routes exist, but they use different fields and do different jobs.
Fields that look alike
| Field | Model | What it does |
|---|---|---|
| video_url (edit) | gemini-omni-flash-1.1 | Applies the prompt to your clip |
| video_url + reference_image_urls | higgsfield-genjutsu | Motion transfer onto 1 to 8 reference images |
| video_url + reference_image_urls | h3-max-recast | Swaps people in the source for 1 to 4 photos |
| reference_video_urls | models that list video references | Guides a new clip; not an edit of yours |
How to fix the call
Decide whether you want to change a clip or create a new one inspired by it. Changing: use Omni Flash edit with a source of 10 seconds or less. Person swap or motion transfer: use the model built for it. New clip guided by footage: use reference_video_urls on a model that lists them, and check the model list first.
Also note the error on mixing fields: a video_url edit cannot carry frame or reference fields in the same request.
