Can Wan 3.0 or Seedance 2.5 return a clip without sound?
Wan 3.0 can and Seedance 2.5 can't. Wan 3.0 includes audio by default and drops it when the request sets generate_audio to false. Seedance 2.5 has no audio switch, so every clip comes back with sound and removing it is a post-production step on your side. A silent option helps for background loops, b-roll that will be scored later and clips that get their own voice-over.
Does Wan 3.0 or Seedance 2.5 go above 1080p?
Only Seedance 2.5 does, through resolution set to 4k. Wan 3.0 tops out at 1080p; a request for a higher tier returns an error listing 480p, 720p and 1080p as the allowed values. At the low end both offer 480p, a common choice for drafts before a final run at a higher tier.
Does Wan 3.0 accept aspect_ratio once an image is involved?
No, Wan 3.0 takes aspect_ratio in text-to-video only. Wan 3.0 lists six ratios for text-to-video (adaptive, 16:9, 9:16, 1:1, 4:3 and 3:4) and takes no aspect_ratio field in image-to-video, first and last frame or reference-to-video; sending one there returns a not supported for this mode error. Seedance 2.5 accepts the same eight ratios in every mode, including 21:9 and 9:21. If a pipeline always sends aspect_ratio, strip it for Wan 3.0 whenever the request carries images.
How many reference images do Seedance 2.5 and Wan 3.0 take?
Seedance 2.5 reads up to 16 reference images in reference-to-video and Wan 3.0 up to 10. Wan 3.0 accepts input images with sides from 240 to 8000 pixels and does not take PNG files with transparency; Seedance 2.5 accepts sides from 300 to 6000 pixels. Both read JPEG, PNG and WebP from public https links.
