Seedance detector: was this video made with ByteDance's Seedance?
Seedance is the video model from ByteDance, the company behind TikTok and CapCut, and it powers the video generator in Dreamina and Jimeng (即梦). Its clips land on Reels and Shorts every day. Paste a link or upload the clip to check it.

Our model flagged 95.3% of the ByteDance clips in our test (Seedance, PixelDance and Seaweed) and called 1.4% of them real. Seedance 2.0 is newer than that test. Our watermark check reads Jimeng, Doubao and “AI生成” labels when they're visible. Every AI tool's results (measured 2026-10-10).
Signs of a Seedance video you can check yourself
- A Jimeng (即梦) or Dreamina mark, or an “AI生成” (AI-generated) label. Chinese rules require visible AI labels, so clips saved from Chinese apps often carry one.
- One scene filmed from several perfectly consistent angles: Seedance can cut between shots by itself, so a multi-angle clip isn't proof of a real camera crew.
- A soundtrack that came with the video: newer versions generate sound too, so matching audio isn't proof either.
- Hands, text and small background details that change between shots.
None of these proves anything on its own: real videos have odd moments too, and the best AI clips have none.
Questions
- Can it detect Seedance 2.0?
- Seedance 2.0 wasn't in our test yet. Earlier ByteDance models were flagged 95.3% of the time, and our video model caught 96.2% of clips from an AI family it never saw in training. Treat any single result as evidence, not proof, and look at the reasons shown.
- Is every video edited in CapCut AI-generated?
- No. CapCut is mostly an ordinary editor: cuts, filters, captions and music don't make a video AI-generated. Only its AI video features create AI footage, and that's what the check looks for.
