Overview
What is Seedance 2.5?
Seedance 2.5 is a ByteDance model available in Starpop. Native-audio video generation from text, start and end frames, or multimodal references with clips up to 30 seconds. ByteDance’s long-form Seedance model for coherent native-audio clips from text, start and end frames, or mixed image, video, and audio references.
Choose Seedance 2.5 when a concept needs up to 30 seconds of continuous storytelling or a larger multimodal reference pack. Starpop keeps the model, input mode, duration, format, resolution, and credit choices in one workspace so a team can move from a first test to a publishable asset without rebuilding the brief in another tool.
