Pick Seedance if…
- You want the cheaper option (starts at $0.022 / sec (2K), Wan starts at Free (open weights); ~$0.07/sec hosted).
- You specifically need Multimodal input (text, image, audio, video — up to 12 refs) or Native synchronized audio, which Wan doesn't ship.
- Your primary use case is Commercial ads & product videos or Cinematic short clips — Wan doesn't list this.
“Seedance is the model to beat for commercial video in 2026. It handles complex motion and multi-reference prompts better than most, and native audio removes a whole post-production step. Access is a little fragmented (Dreamina for consumers, BytePlus for the API), but the output quality justifies the friction.”— Editor’s take
