What separates Seedance 2.0 from Wan 3.0 on paper?

Seedance 2.0 stops at 15 seconds and sets aspect_ratio in image modes, while Wan 3.0 runs to 30 seconds, adds a 480p tier and can turn audio off. Wan 3.0 and Wan 3.0 Prime share one column because every field matches.

Can Seedance 2.0 or Wan 3.0 make a clip longer than 15 seconds?

Only Wan 3.0 can, with up to 30 seconds per request. Seedance 2.0 rejects a duration above 15 with an error asking for an integer between 4 and 15, so a 20 second shot has to be split into two requests and joined afterwards. Wan 3.0 takes the whole 20 seconds, or anything up to 30, in one request. At the short end, Wan 3.0 also accepts 2 and 3 second clips, which Seedance 2.0 does not.

Do Seedance 2.0 and Wan 3.0 both have a 480p draft tier?

Only on Wan 3.0 and Wan 3.0 Prime. Seedance 2.0 starts at 720p, which is also its default. Seedance 2.0 Fast, a separate model id, is fixed at 720p and takes no resolution field at all, so it does not add a lower tier either; Seedance 2.0 Fast vs Seedance 2.0 compares the two.

Can Seedance 2.0 and Wan 3.0 set the frame shape when animating a still?

Seedance 2.0 can and Wan 3.0 cannot. On Seedance 2.0 the request sets it: image-to-video takes 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16, and first and last frame adds adaptive. On Wan 3.0 the request cannot, because image-to-video, first and last frame and reference-to-video take no aspect_ratio field. In reference-to-video, Seedance 2.0 narrows its list to 16:9, 9:16, 4:3 and 3:4.

Where does Wan 3.0 Prime fit in?

Wan 3.0 Prime accepts exactly the request Wan 3.0 accepts: the same four modes, 2 to 30 seconds, 480p to 1080p, six text-to-video ratios, up to 10 references and the generate_audio switch. Moving between the two is a change of model id from wan-3.0 to wan-3.0-prime, and the per-second price changes with it.
