Which video_url row to call: Omni edit, Recast or Motion Transfer

Only three Sume rows accept a source clip in video_url: gemini-omni-flash-1.1 edits a clip from a text prompt, h3-max-recast replaces the people in a clip with people from 1 to 4 photos, and higgsfield-genjutsu transfers motion onto reference images when its provider is configured. sume/auto never routes to the second or third, so you must name them.

The three rows side by side

Pick by what you want to change. Use the table's third column as the first filter, and the price column to estimate the bill. Per-second Sume rates are the fal list times 1.25, as documented in the Video Router page.

Differences that decide it

Omni edit takes only a prompt and the clip, with native synced audio always on, and no reference images. Recast takes one photo per new person, keeps the source motion, camera, cuts and sound, and makes the prompt optional. Genjutsu appears in the catalog only when its provider is configured, so check GET /v1/video-router/models before you build on it.

Rule of thumb

If the change is an object, a colour or a setting, Omni edit is the cheaper per-second route. If the change is a person, Recast is the purpose-built route, at a higher per-second price. For anything else, generate fresh with a first frame instead of editing.
