Seedance 2.0 vs Wan 3.0
Both video models are in the same composer on Labnana, take a prompt or a still or reference footage, and return a watermark-free MP4. Where they part company is length and framing: Wan 3.0 runs twice as long, and Seedance 2.0 is the one that offers a 21:9 crop.
The table is read from each model page, tier by tier — where the two tiers of a model differ, the cell names which tier does what.

Which one to pick
Wan 3.0
It is the only one of the two that goes there: the duration row shows Wan 3.0 running from 2 to 30 seconds against Seedance 2.0’s 4 to 15. Anything longer on Seedance has to be assembled from more than one generation.
Seedance 2.0
The aspect-ratio row is the whole argument — 21:9 is on Seedance 2.0 and not on Wan 3.0. Choosing Wan and cropping to 21:9 afterwards throws away vertical resolution you paid to render.
Seedance 2.0
Seedance 2.0 accepts up to 3,000 characters, 500 more than Wan 3.0’s 2,500. A brief between 2,501 and 3,000 characters fits Seedance without shortening.
