Seedance 2.5 FAQ
How long can it generate?
The official model supports up to 30 seconds in a single generation plus multi-round extension. Durations currently available on PixZoo appear in the generator.
How many references can I add?
Seed lists an official model maximum of 30 images, 10 videos, and 10 audio clips in one pass. PixZoo shows the reference types and counts currently supported by its integration.
What is it best for?
Narrative ads, brand stories, character performance, dramatic sequences, product videos, and social content where visuals and sound need to move together.

Not necessarily. Official documentation describes the full model; reference, timestamp editing, green-screen, and other controls available now are those displayed in the live generator.
