The single biggest factor in how an AI video template turns out is the photo you feed it. Templates can only animate what they can see, so a few minutes choosing the right picture saves a lot of retries.
Light first. Even, natural light from the front shows the face clearly. Harsh shadows across one side of the face often turn into flicker once the face starts to move.
One person, centred. Most templates are trained on a single subject. If there are other people in the shot, crop them out before you upload.
Show what will move. A dance or walking template needs shoulders and arms in frame. A portrait or scene-swap template is happy with a head-and-shoulders crop.
Keep it recent and unfiltered. Beauty filters smooth away the detail the model uses to track the face. Add filters to the finished clip instead.
Check resolution. Screenshots of screenshots lose sharpness. Use the original file where you can.
