# FrameFixer

> Rebuilds dropped or damaged frames from their neighbours.

Rebuilds dropped or damaged frames from their neighbours. Frames takes a frame list ("12 15-17"). Method: interpolate (RIFE 4.26 in the AI worker, from the nearest good frames before and after, at full size up to 4K, averaged with a reversed pass; two bad frames in a row get 1/3 and 2/3), hold previous, hold next. Connect a Mask to replace only the masked area (alpha; invert mask flips it). Other frames pass through. While RIFE runs the viewer shows the previous good frame; the job log is under Details.
