Seedance 2.5 at a glance
Seedance 2.5 is the flagship of ByteDance's Seedance family, sitting above the 2.0, 2.0 Fast and 2.0 Mini tiers. Its headline change is length: one generation can run to 30 seconds — double the 2.0 ceiling — so a multi-beat shot stays coherent instead of being glued together from 15-second pieces.

Why pick Seedance 2.5 in Shorz
30 seconds in one take
Clips from 4 to 30 seconds come out of a single generation, so motion, lighting and characters stay continuous across the whole shot.
50 reference assets
Guide the shot with up to 30 images, 10 videos and 10 audio clips — more than three times what Seedance 2.0 accepts.
Audio-only references
Unlike 2.0, Seedance 2.5 can start from an audio reference alone — useful for shots that need to follow a beat or a voice.
Prompts in 11 languages
Write the prompt in your own language; 2.5 understands 11 natively, up from 5 in the 2.0 family.
mp4 or mov
Export as mp4 for posting or as mov when the clip is heading into a grading or compositing pass.
Lands in a real editor
The clip saves to your Shorz library as a normal file — trim it, caption it, score it and reframe it without leaving the app.
Best for
- Long single shots
- Character-consistent sequences
- Product films
- Music-driven scenes
- Premium B-roll
