Prepare your source
Use a single continuous shot. Keep one person visible, with clear head and body proportions. Trim to 3–10 seconds and export a standard MP4 at 24–60 fps. Both dimensions should be 720–2160 pixels; keep the file under 30 MB.
Choose the right workflow
Character swap edits the original shot around a new identity. Motion transfer animates the person in your reference image using the source performance; the image also guides the background and overall look.
Give the model a clear reference
Use a sharp JPG, PNG, or WebP image under 10 MB. Match a full-body motion clip with a full-body image. Avoid faces hidden by hands, busy crowds, and extreme angles.
Write a focused description
For character swap: “Replace the performer with the character in my reference image. Keep the camera framing and movement. Preserve the studio background.” For motion transfer: “The character performs the same gestures as the reference video in a softly lit studio.”
