# Choosing the right source photo for video face swap

The source photo decides most of the quality of a video face swap. A quick checklist:

Contents

Resolution: the face should be at least a few hundred pixels wide.
Angle: front-facing or slightly turned, matching the main angle in the video.
Expression: neutral or a slight smile; extreme expressions get copied into every frame.
Obstructions: no sunglasses, masks, hair across the eyes or hands near the face.
Light: soft and even; avoid harsh shadows and strong color casts.
Age and era: an old scanned photo works, but scan it sharply and remove dust first.

# Quick test

Run a 5-second clip first. If the face looks right in the first second and at the midpoint, run the full video.
