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. | Spec | Kling 4.0 | Seedance 2.5 | Wan 3.0 | | --- | --- | --- | --- | | Vendor | Kuaishou | ByteDance | Alibaba | | Duration | 3 to 30 s, default 5 | 4 to 30 s, default 5 | 2 to 30 s, default 5 | | resolution field | 720p, 1080p | 480p, 720p, 1080p, 4k | 480p, 720p, 1080p | | Default tier | 720p by default | 720p by default | 720p by default | | Text-to-video ratios | 16:9, 9:16, 1:1, 21:9 | adaptive, 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, 9:21 | adaptive, 16:9, 9:16, 1:1, 4:3, 3:4 | | Image-to-video ratios | No aspect\_ratio field | adaptive, 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, 9:21 | No aspect\_ratio field | | Reference images | Up to 10 (r2v) | Up to 16 (r2v) | Up to 10 (r2v) | | Reference ratios | 16:9, 9:16, 1:1, 21:9 | adaptive, 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, 9:21 | No aspect\_ratio field | | Audio | Always on, no switch | Always on, no switch | On by default, generate\_audio can turn it off | Model pages: [Kling 4.0](https://makernice.com/models/kling-4-0/), [Seedance 2.5](https://makernice.com/models/seedance-2-5/) and [Wan 3.0](https://makernice.com/models/wan-3-0/). Two-way versions: [Kling 4.0 vs Seedance 2.5](https://makernice.com/blog/kling-4-0-vs-seedance-2-5/) and [Seedance 2.5 vs Wan 3.0](https://makernice.com/blog/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.

Choose by the one requirement only one model meets, as there is no side-by-side quality test of the three here: Seedance 2.5 for 4k or more than 10 references, Wan 3.0 for silent output or a 2 second clip, and Kling 4.0 or Seedance 2.5 for reference-to-video framed at 21:9. - 4k output, 9:21 vertical framing, or more than 10 reference images: Seedance 2.5. - A clip without audio, or a 2 second clip: Wan 3.0. - Reference-to-video framed at 21:9: Kling 4.0 or Seedance 2.5. - A 3 second clip: Kling 4.0 or Wan 3.0. - A 480p draft: Seedance 2.5 or Wan 3.0. ## Frequently asked questions #### Do all three accept 30 second clips? Yes. Kling 4.0, Seedance 2.5 and Wan 3.0 each accept up to 30 seconds in one request. Their minimums differ: 3, 4 and 2 seconds. #### Which of Kling 4.0, Seedance 2.5 and Wan 3.0 has a 4k tier? Only Seedance 2.5. Kling 4.0 stops at 1080p and so does Wan 3.0. #### Which takes the most reference images? Seedance 2.5, with up to 16. Kling 4.0 and Wan 3.0 take up to 10 each. #### Can I send the same request to all three? A text-to-video request at 720p or 1080p, 16:9, 9:16 or 1:1, and 4 to 30 seconds is valid on all three. Requests with images need the aspect\_ratio field adjusted per model, and Kling 4.0 reads JPEG and PNG images only. ## Models in this post Video ### Kling 4.0 Kling 4.0 makes 3–30 second clips with sound from text, a first frame, first and last frames, or up to 10 reference images, at 720p or 1080p.
