The long takeByteDance

Seedance 2.5.
Thirty seconds, one take.

Double the ceiling of 2.0. Up to 30 seconds in a single generation, with native audio and thirty reference images, so a whole scene comes out of one prompt instead of four stitched clips.

From 58 credits per 5 seconds. Video generation starts on the paid plans. Native output is 480p and 720p.

What is Seedance 2.5?

Seedance 2.5 is ByteDance's long form video model, launched in July 2026. It generates a single continuous clip of 4 to 30 seconds with a synchronized audio track, and accepts up to 30 reference images, 10 reference videos and 10 audio inputs in one request. That reference budget is the point: a cast, a product line and a location can all be pinned at once, so a thirty second scene stays consistent without the character drift that comes from stitching four separate generations together. On APImage it renders natively at 480p or 720p and draws on the same credit pool as every other model.

Why this model

What Seedance 2.5 does that the others do not.

Thirty seconds, uncut

A full clip in one pass, with no stitching and no seam where two generations were taped together. Twice the ceiling of Seedance 2.0.

Thirty references

Images, clips and audio, tagged and addressable from the prompt. Enough to lock a cast, a product line and a location in the same generation.

Audio in the box

Speech, effects and ambience are generated with the picture and land on the beat, so there is no separate pass to sync afterwards.

Identity that survives the take

Faces and products hold across thirty seconds. Length is where consistency usually breaks, and this is the model built for it.

What people make with it

Where it earns its credits in real work.

Full length ads

A thirty second spot is the standard unit of paid media. This renders one as one thing, not as a stitched sequence.

Multi shot narrative

Set up, develop and pay off inside a single generation, with the same cast in every beat.

Explainers and demos

Long enough to walk through a product properly, with narration generated alongside the picture.

Character driven UGC

Thirty reference images pin a presenter hard enough to reuse them across a whole campaign.

Music led social

Native audio means the cut lands on the beat instead of being nudged into place in an editor.
