How it differs from Kling Motion Control (moving a person's motion)
For transferring the movement of a person in a reference video onto a character, Kling's Motion Control is widely used. However, Kling Motion Control can only drive one person at a time: if the reference video contains several people, it follows the largest person on screen (per third-party articles quoting Kling's official guide). Seedance 2.5 accepts up to 10 reference videos, so you can direct motion and camera work through reference material. For multi-person dance videos, a different kind of tool is needed.
Which should you pick?
| What you want to do | Recommended | Why |
|---|---|---|
| Make a 30-second single take right now | Seedance 2.5 | Already released, and generates up to 30 seconds in one pass |
| Make a short video with audio, quickly | Seedance 2.5 | Generates video and audio together |
| Move one person's dance or performance onto a character | Kling Motion Control | Follows the movement of the person in the reference video |
| You can wait for the highest quality and HDR | Kling 4.0 | 4K and 10-bit HDR have been announced, but the final specs are not settled |
The vendor itself lists the physical realism of complex motion and scenes with multiple interacting subjects as open challenges for Seedance 2.5. For heavy action, try shorter clips.
