Question 1

What exactly gets preserved from the reference video?

Accepted Answer

Motion, choreography, blocking, timing, and camera work (angle, framing, movement) are preserved. The original performers' identity, wardrobe, and colors are replaced, while the real filming location, architecture, and lighting are kept intact.

Question 2

Can I recast more than one performer?

Accepted Answer

Yes — provide one character reference photo per performer in `images_list` (up to 9). Each photo gets its own automatically generated multi-angle identity sheet, so multiple performers can be swapped in a single request.

Question 3

Does the output include generated audio?

Accepted Answer

No, not by default. `generate_audio` defaults to false, since a motion-control recast is meant to preserve an existing performance rather than add fabricated music or sound effects. Set it to true to opt in.

Question 4

Do I need to write a detailed prompt?

Accepted Answer

No — `prompt` is optional. If omitted, the character and environment roles are inferred automatically by analyzing the reference video and the character images you provide.

Question 5

How is cost calculated?

Accepted Answer

Base generation cost is the same as Seedance 2 Omni Reference (rate x output duration, plus a discounted rate for the reference video's own duration), plus internal preprocessing: depth extraction ($0.04/sec of the source video), an environment clean-plate pass (2 frames, $0.06 each), and one character-sheet generation per reference photo ($0.09 each). Example: 5s output, 5s reference video, 1 character photo, 'high' quality ≈ $2.46 total.

Question 6

What aspect ratios and resolutions are supported?

Accepted Answer

21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 aspect ratios; output renders at 720p.

Aanbieder	Estimated Rate	Opmerkingen
muapiapp	~$2.46 for a 5s recast (5s reference video, 1 character photo, high quality)	Single billed request covers the full pipeline: depth extraction, environment clean-plate generation, character-sheet generation, and the final recast render.
Fal.ai	Niet beschikbaar	No equivalent single-request motion-recast pipeline is offered — achieving the same result would require manually chaining several separate models.
Replicate	Niet beschikbaar	No equivalent single-request motion-recast pipeline is offered on Replicate.
