About AI Avatar Multi

Takes one image plus `first_audio_url` and an optional `second_audio_url` to produce a video in which the people in the picture speak in turn. A required `prompt` guides the scene. Output is 480p or 720p, with `num_frames` from 41 to 241. `use_only_first_audio` limits the result to the first track, and `acceleration` can be none, regular or high.

Parameters

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