Lots of video editing gear uses optical shaft encoders. Typical
failure is bushing wearout that alters the alignment of the rotary vs
fixed disk. You'll find excess axial 'play' and often side-side play
as well. Some decent lubricant early on sold have increased the life.

Have you ever tried the Griffin Powermate? It has a lot better feel
that the old Panasonic jog wheels I used to use to edit video.
