About H3 Max

Edits a source video by adding a new scene between `start_time` and `resume_time` (each 1.625 to 60 s). The scene can be guided by a `prompt`, up to 9 reference images and up to 3 reference videos. `duration` is 5 to 13 seconds, output is 480p or 768p, and `color_match` is on by default to blend the insert with the source.

Parameters

Send either the canonical name or the native name, not both. Canonical names
