About EchoMimic V3

Animates a still portrait so it speaks along with supplied audio. Required inputs are `image_url`, `audio_url` and `prompt`. Tune results with `num_frames_per_generation` (49 to 161), `guidance_scale` (1 to 10) and `audio_guidance_scale` (0 to 10), and use `seed` for repeatability. Returns a single video.

Parameters

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