Stock avatar shortlist
Sixteen of HeyGen’s 1,264 video avatars — the ones the $0.60/min tier
uses. These are HeyGen’s own preview reels, not renders, so they cost nothing.
What to look for: are the hands in frame, and do they move?
The score is measured pixel change below the head, so it separates real body movement from a
talking head. Higher is better.
What this does not tell us: how any of them looks rendered through the API on Avatar III,
or whether they export with a transparent background. That needs a paid render.
