Kling 2.6 Motion Control is Kuaishou's budget motion transfer model, released in December 2025. It takes the movement from a reference video and applies it to the subject of a reference image, so a photo of a character can perform the same dance, gesture or walk. On Jantaris the subject's facing follows the image, so source clips run 3-10 seconds, and the source audio is kept. You choose std or pro quality. The 30-second video-facing mode and the audio switch are not available in Jantaris yet. Billing is per second of the source clip.
Best for
- High-volume motion trend videos on a budget
- Testing a motion idea before a v3 render
- Avatars that copy simple gestures
- Social templates reused with many different images
Prompting tips
- Trim the source clip to the exact movement you need, since billing follows its length.
- Match the image's pose and framing to the video's opening frame for a cleaner transfer.
- The source audio stays in the output, so it works well for movement synced to music.
- Start on
