Reference Clip Checker for AI Motion Transfer

Motion transfer copies the movement from a reference video onto a still photo of your own subject. The result can only be as clean as the clip you give it. Most failed renders trace back to the reference: it is too long, the dancer leaves the frame, the camera shakes, or there is a hard cut halfway through. Use the checker below before you spend a render, then read the notes on what each warning means.

What makes a good reference clip

Matching the photo to the clip

Your photo should show the subject in roughly the same pose and framing as the first frame of the reference: standing, full body, facing the camera. A head-and-shoulders selfie paired with a full-body dance clip forces the model to invent legs. The guide to image-to-video tips covers choosing a source photo in more detail, and the motion control page shows how the photo and the clip are combined.

When the warnings are fine to ignore

A shape mismatch is not always a problem: if your photo has empty space around the subject, the re-framing may cost nothing. A short clip works for a single gesture such as a wave or a head turn. Use the warnings as questions, not rules.

Where to find clips and prompts

If you do not have a clip yet, the motion transfer prompt library pairs each prompt with the clip it produced, and the dance prompts collect trend choreography. To swap a person in an existing video instead, see replacing the person in a video. When the clip passes, take it to Oraclip with your photo.
