Seedance 2.5 vs Kling 4.0 vs Wan 3.0: which 30-second model fits?

Kling 4.0 from Kuaishou, Seedance 2.5 from ByteDance and Wan 3.0 from Alibaba all generate a single clip of up to 30 seconds through the same Makernice API, and all three support text-to-video, image-to-video, first and last frame and reference-to-video. They differ on resolution tiers, on where the frame shape can be set, on reference limits and on audio. This page lays out those catalog facts and the price of a full 30 second clip; it does not rank output quality.

How do Seedance 2.5, Kling 4.0 and Wan 3.0 differ?

Seedance 2.5, Kling 4.0 and Wan 3.0 share the 30 second ceiling and all four modes, so they differ on tiers, aspect_ratio by mode, reference limits and the audio switch. The table lists every catalog field for the three.

Model pages: Kling 4.0, Seedance 2.5 and Wan 3.0. Two-way versions: Kling 4.0 vs Seedance 2.5 and Seedance 2.5 vs Wan 3.0.

Which of Seedance 2.5, Kling 4.0 and Wan 3.0 has the most resolution choices?

Seedance 2.5, with 480p, 720p, 1080p and 4k. Wan 3.0 offers 480p, 720p and 1080p, and Kling 4.0 offers 720p and 1080p. The three share 720p as the default, so a request without resolution renders at 720p on any of them, and they share 1080p as a common top tier when 4k is not needed.

Where do Seedance 2.5, Kling 4.0 and Wan 3.0 accept aspect_ratio?

Seedance 2.5 accepts aspect_ratio in every mode, Kling 4.0 in text-to-video and reference-to-video, and Wan 3.0 in text-to-video only. The accepted values per model:

• Seedance 2.5: in all four modes, with the same eight values (adaptive, 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, 9:21).
• Kling 4.0: in text-to-video and reference-to-video (16:9, 9:16, 1:1, 21:9); not in image-to-video or first and last frame.
• Wan 3.0: in text-to-video only (adaptive, 16:9, 9:16, 1:1, 4:3, 3:4).

Sending aspect_ratio to a mode that does not list it returns a not supported for this mode error, so a shared request builder should drop the field per model and mode.

Can Seedance 2.5, Kling 4.0 or Wan 3.0 return a silent video?

Only Wan 3.0 can, by setting generate_audio to false; audio is on by default. Kling 4.0 and Seedance 2.5 include audio on every clip and accept no audio switch, so silence on those two is a post-production step.

What does a full 30 second clip cost at each tier?

On Makernice, a 30 second clip at 720p is $7.78 on Seedance 2.5, $5.04 on Kling 4.0 and $2.37 on Wan 3.0, on price list v15 (November 12, 2026). Per-second rates are the same across all four modes of a tier. The 30 s column = per-second price × 30, rounded to the cent; the quote shows the exact amount. Failed and timed-out runs aren't charged. Note: if a finished output is blocked by output moderation for a policy violation, the run is still charged. You can contact support for a manual review.
