AI motion control that copies any move onto your character

What you need before you start

Motion control works from two inputs, and their quality decides most of the result.

• A reference clip of 3 to 30 seconds (MP4, MOV or WebM, up to 50 MB) with one performer, the full movement in frame, a steady camera and no hard cuts.
• A character photo with one subject and even lighting, framed like the performer: a half-body photo for a half-body clip, a full-body photo for a full-body one. A saved character works well.
• Permission to use both. Only use clips and photos you have the rights to use.

Which motion control model to use

VidBoss AI offers three Kling Motion Control versions. They work the same way and differ in resolution and price. Kling 3.0 Pro renders in 1080p; Kling 3.0 Standard and Kling 2.6 Standard are 720p beta options that cost less, which makes them handy for testing a trend before you spend credits on a final version. The length of the result follows your reference clip, and the exact credit price is shown before you generate.

Common problems and how to fix them

• Arms or hands look wrong: pick a reference clip where the hands stay in frame and move less quickly.
• The character drifts from your photo: use a sharper, front-facing photo, or a saved character.
• Parts of the body are cut off: match the photo framing to the reference clip.
• The clip is rejected: trim it to between 3 and 30 seconds, and use footage with one performer and no hard cuts.
• A fast-moving camera or several people in the clip give the model too much to follow, so choose a steadier reference.
• If a generation fails, VidBoss AI tries the other motion models on the credits already reserved, and refunds the credits automatically if none of them can make the video.

Motion control or replacing a person in a video?

Kling Motion Control rebuilds the performance as a new video with your character, so the background is generated and the character can even be a pet. If you want to keep your original footage and only swap the person, use the replace-character tools instead. They edit your clip, keeping the scene, camera and sound.
