Biker Birthday Cake AI video: why does the face not look like me?
Updated:
Short answer
Faces drift when the model cannot see the face clearly, and this trend happens at night with warm candle light. Use a sharp, bright, front-facing photo where the face fills a third of the frame, then check the free 5-second preview before spending credits.

Common causes
- Small face: you are far away in the photo.
- Helmet or sunglasses in the photo: the model has to guess.
- Candle light: the warm glow tints skin a little, as in the real clip.
A quick fix routine
- Pick a new photo that follows the photo guide.
- Run the free preview and compare the face with your photo.
- Only then render the full video, because each full render costs 1 credit.
Questions people ask
Is a changed face a failed video?
No. A failed video is one that did not finish, and those return the credit automatically.
Why is the face harder to judge at the end?
The last second is black and white, so check the face just before the candles go out.
