ByteDance: seedance-2.0-mini

Seedance 2.0 Mini is the lightweight, cost-oriented tier of ByteDance's Seedance 2.0 video generation family. It shares the family's unified multimodal audio-video generation architecture and prompt system, but trades output scale for speed and price: it produces4- to 12-second clips (5 seconds by default) at 480p or 720p (720p by default), in aspect ratios ranging from 16:9, 4:3, 1:1 and 3:4 to 9:16, 21:9 and 9:21. On the input side it handles text-to-video, image-to-video, reference video, and reference audio used as background music. Up to four reference images can steer characters, avatars, clothing or environments, first- and last-frame images can anchor a shot, and avatar references can draw on trusted assets from a library. Video can be generated together with audio, while reference audio must be paired with a reference image or video. It is built for high-throughput, cost-sensitive work: concept validation and storyboard drafts, large batches of variants, early testing of social and vertical ad creative, and scaled video asset production for e-commerce and marketing. Because output tops out at 720p and 12 seconds, a common pattern is to prototype with Mini and deliver finals with Seedance 2.0 (up to 4K and 15 seconds) or Seedance 2.5 for longer narrative pieces.
