What is Seedance 2.5?
Seedance 2.5 is the newest Seedance model from ByteDance and the longest-running one we offer: a single generation can reach 30 seconds. That makes it the pick when a clip needs to tell a small story in one take instead of being stitched together from short shots. It accepts a text prompt, or a prompt plus a first-frame photo, and can generate a soundtrack with the video.
Why use Seedance 2.5
Up to 1080p
Pick 480p for drafts, 720p for everyday posts or 1080p when the clip is the final version.
Optional audio
Switch audio on and the video comes with generated sound, ready to post without an extra editing step.
Six aspect ratios
Vertical 9:16 for TikTok, Reels and Shorts, plus 16:9, 1:1, 4:3, 3:4 and 21:9 for everything else.

Tips for better Seedance 2.5 videos
- Describe one subject, one setting and one camera move. Long clips drift when a prompt lists too many ideas.
- Start at 480p or 720p to check the motion, then re-run the good one at 1080p.
- For a longer clip, say what changes over time: "starts wide, ends in a close-up".
- Use a clear, well-lit first-frame photo when you need the subject to look the same throughout.
