Seedance 2.5, next generation of AI Videos.
ByteDance has announced Seedance 2.5 with 30-second single-shot generation, native 4K, and up to 50 multimodal reference inputs — a step change for AI video. Here's what has been announced, and what it will mean inside the ScriptMotion workflow once it ships.
Seedance 2.5 is not officially rolled out by ByteDance to customers. We, at ScriptMotion, aim to integrate it as part of our offerings as soon as it is officially released by ByteDance.
Generated on ScriptMotion using Seedance 2— no editing. Seedance 2.5 isn't released yet, so this shows Seedance 2 output.
30 seconds in one pass
ByteDance says Seedance 2.5 generates a single continuous 30-second clip from one prompt — roughly double Seedance 2. Unverified until we can measure it ourselves.
Up to 50 reference inputs
The announced reference budget rises from 12 to 50 multimodal inputs — images, clips, and audio — which would help hold a brand look across a longer edit. Announced, not yet confirmed.
Native 4K, 10-bit colour
4K output with 10-bit colour depth is claimed, which matters for grading headroom and gradient banding. We'll confirm against real output once access opens.
How to create with Seedance 2.5
We integrate on release
Seedance 2.5 isn't wired into the workflow yet. When ByteDance opens general access, it goes through our standard model-integration checks before it appears in the picker.
We measure the real cost
Credit burn rate is set from measured provider cost, never from an announcement. That's why the credit cost above reads TBC rather than a guess.
