Pick a clear character photo
Use a sharp, well-lit photo where your character is easy to see. A clean full body shot gives the swap more to work with.
Choose a video with one clear mover
Simple moves like a dance, a walk or a wave work best. One person in the frame is easier to follow than a busy crowd.
