This happens when outputting to libx264, as well.

Bigboooy21 commented 2 months ago

Dont know if this is related, but for me it happens when I use the "Use last frame" option when no face is detected. When I use "retry rotated" its fine.

RoopUser commented 2 months ago

That must be it! I just noticed it happening too since the release (when I started using the option). Will confirm...

C0untFloyd commented 2 months ago

Most likely that option. This inserts the previous frame if no face was detected. This prevents face flickering but introduces noticeable stuttering if there is no face for a longer time. I think the number of frames to re-use the old should be exposed to the user (currently 15 if I'm not mistaken).
