Kling 3.0 from Kuaishou and Seedance 2.0 from ByteDance land on the same 15 second ceiling and both always return audio, so the choice comes down to what you can put into a request. Seedance 2.0 takes up to 9 reference images, sets aspect_ratio when animating a still and allows 4,000 character prompts. Kling 3.0 starts at 3 seconds, has a separate 4K variant for text-to-video and caps prompts at 2,500 characters. This page sticks to catalog facts and Makernice prices; it does not score output quality.

What is the difference between Kling 3.0 and Seedance 2.0?

Both stop at 15 seconds and always return audio, so the differences sit on the input side: Seedance 2.0 adds reference-to-video and a resolution field. Kling 3.0 starts at 3 seconds and splits its tiers into Kling 3.0 Standard at 720p, Kling 3.0 Pro at 1080p and Kling 3.0 4K at 4k. The table lists every catalog field side by side.

Can Kling 3.0 use reference images like Seedance 2.0?

No, only Seedance 2.0 can. Its reference-to-video mode takes 1 to 9 images as reference_images and accepts 16:9, 9:16, 4:3 or 3:4 as the aspect ratio. None of the three Kling 3.0 variants offers reference-to-video. If you want to stay on Kling and still use references, Kling 4.0 takes up to 10; Kling 4.0 vs Kling 3.0 walks through that move.

How long can a Kling 3.0 or Seedance 2.0 prompt be?

Kling 3.0 Pro, Standard and 4K reject prompts longer than 2,500 characters after trimming. Seedance 2.0 has no model-specific limit, so it follows the API-wide maximum of 4,000 characters. A long shot list written for Seedance 2.0 may need shortening before it runs on Kling 3.0.

How do you get 720p, 1080p or 4K on Kling 3.0 and Seedance 2.0?

On Seedance 2.0 you choose with a field: resolution set to 720p or 1080p, with 720p as the default. On Kling 3.0 you choose with the model id: kling-3.0-standard is the 720p tier, kling-3.0-pro the 1080p tier and kling-3.0-4k the 4k tier, in text-to-video only. Kling 3.0 rejects a resolution field with an error saying the model has a fixed resolution, so drop the field when switching a Seedance 2.0 request over.

How much do Kling 3.0 and Seedance 2.0 cost per second?

On Makernice, Seedance 2.0 is $0.1704 per second at 720p and Kling 3.0 Standard is $0.1209, on price list v15 (November 12, 2026). One per-second rate per tier applies to every mode; clip price = per-second price × seconds, rounded to the cent, and the quote gives the exact figure.

Which should I choose, Kling 3.0 or Seedance 2.0?

Choose by what your request needs, since no side-by-side quality test of the two is published here: Seedance 2.0 fits reference images, wide 21:9 or 4:3 framing and long prompts. Kling 3.0 fits a 3 second clip, and Kling 3.0 4K adds text-to-video at 4k.

  • Reference-driven shots with up to 9 images, 21:9 or 4:3 framing, or prompts over 2,500 characters point to Seedance 2.0.
  • A 3 second clip, or text-to-video at 4k with audio, points to Kling 3.0 (the 4K variant for the latter).
  • For a fixed tier with no resolution field to manage, Kling 3.0 Standard or Pro does that by design.

Frequently asked questions

Does Seedance 2.0 have a 4K option?
No. Seedance 2.0 renders 720p or 1080p. For 4k, use Kling 3.0 4K in text-to-video or Seedance 2.5, which lists 4k as a resolution value.
Can Kling 3.0 and Seedance 2.0 both turn an image into a video?
Yes, except Kling 3.0 4K. Kling 3.0 Pro, Kling 3.0 Standard and Seedance 2.0 all take a start image (image-to-video) or a first and last frame; only Seedance 2.0 lets you set aspect_ratio when animating a still. Kling 3.0 4K is text-to-video only.
Is Kling 3.0 or Seedance 2.0 better quality?
We haven't published a side-by-side quality test of the two, so this page doesn't rank their output. Quote the same prompt on both and compare the clips; a quote returns a price without creating a job or charging your balance.
Can I make a 3 second clip with Seedance 2.0?
No. Seedance 2.0 starts at 4 seconds. Kling 3.0 accepts 3 seconds on every variant.
