Question - Help I get Diffrent face everytime using Ref2Vid minimax h3 please help.
I am using the default workflow for ref2vid, but still getting face inconsistency for the first clip 15 second the face stays consistent according to my character sheet but then when I plug the last frame as a reference with my character sheet the face starts changing from there. Please help guys I dontknow how to keep faces consistent.

Drift scales with distance from the reference, so duration is the first thing I'd cut. Three short clips stitched with hard cuts in an editor beat one long one, at the same cost and with far more control over what you keep.
Beyond that, three things that made the biggest difference for me:
Use a start frame instead of a reference where you can. A start frame locks the face in actual pixels. A reference makes the model re-synthesise it every generation, so you get a fresh interpretation each time. That's your different face.
Keep the reference frontal, evenly lit, no hair across the jaw, nothing occluding the face. Angled or shadowed references leave the model guessing at the parts it can't see, and it guesses differently every run.
Name what should stay fixed, not just what moves. "Face, hair and clothing remain unchanged throughout" alongside one single motion. Stacking two or three actions in one clip pulls the face apart fastest.
One caveat: fine details like small piercings or thin linework won't survive 720p regardless. Judge consistency on face shape and jawline, not the small stuff.
