Seedance is ByteDance's video model lineup — the same company behind TikTok, CapCut, and Dreamina. Seedance 2.5 is built for complex scenes: fast movement of people and animals, object interactions, liquids, and fabric. Sound is generated along with the visuals — ambient noise, music, and speech, with the character's lips moving in sync with the words.
The model works in both modes. Image-to-video brings a photo to life while preserving the subject's appearance and setting. Text-to-video builds a scene from scratch in 16:9, 9:16, or 1:1 format. Clips run 5 or 10 seconds at 720p resolution.
Seedance 2.5 is the most expensive video model on the platform, best suited for final cuts where complex action and speech matter most. For drafts and quick concept checks, MiniMax H3 Turbo is a more cost-effective choice, while Kling 4.0 and Grok Imagine 1.5 handle longer shots up to 15 seconds.
