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

The shot has to run longer than 15 seconds

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.

You want a cinematic 21:9 frame

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.

The brief is long and comes with a lot of reference material

Wan 3.0

It takes a longer prompt and more reference images per request — both visible in the prompt-limit and reference rows. A detailed multi-shot description that gets truncated elsewhere survives intact here.
