What you can give it

A prompt on its own.
Frames: a start frame, and an optional end frame. Frames can’t be combined with references.
References: images, videos and MP3 audio.
- Seedance 2.5 takes up to 50: 30 images, 10 videos and 10 audio clips. Videos and audio can each run 2 to 30 seconds, 30 seconds in all.
- Seedance 2.0 models take up to 10: 9 images, 3 videos and 3 audio clips, with up to 15 seconds of video. Audio needs an image or video beside it.

With references, Video mode chooses what Seedance does with them: Reference media, Edit video or Extend video. Edit and extend need a reference video. See Make a video. Seedance refuses a recognizable person in a reference that isn’t marked as a real person. See Mark a real person.
