ByteDance Seedance 2.5 enables 30-second full-scene video generation with audio
ZashManson · reddit · 2026-08-19
ByteDance's Seedance 2.5 model extends single-generation video length to 30 seconds, supporting 4K output and synchronized audio including dialogue and sound effects. This allows for the creation of multi-shot sequences with camera movement, character action, and consistent audio from a single prompt, shifting the basic unit of AI storytelling from individual shots to full scenes. Creators have already used this to produce viral 30-second shorts.
