Seedance 2.5 Adds Two Story Extensions

Seedance 2.5 adds two post-generation extensions to its short-story workflow. ByteDance says one generation can run up to 30 seconds, and the product page describes the option to extend twice. 12 The same official overview highlights continuity across characters, environments, narrative pacing, and audio-visual flow. 1

For creators, the useful habit is to review the first ending before extending, so the next shot begins from a clear handoff. Keep the characters, setting, pacing, and sound references consistent as the story grows.
