Scanning speed is usually related to resolution, as higher-resolution sensors
(with global shutters and good dynamic range, usually CCDs) are slower than
lower resolution sensors. Our 3296 x 2472 sensor can scan at 20+ fps, but our
5K sensor can only scan at 8 fps. At 20 fps, in a 16 hour 2-shift day, that's
about 1.1 million frames at 3.3K. What is the resolution of the Mueller?

Now called AEO-Sound. The PC version runs at about 1/3 realtime, which is a
huge improvement. Interestingly, you can run several threads of it at the same
time. One Kinetta owner runs eleven copies of it at night on a Mac, which
effectively speeds things up. The quality of AE0-Sound is far better than most
analog reproducers, and it deals with problem tracks -- negative tracks, VD
tracks, mis-positioned tracks -- very well. Plus, no added wow-and-flutter
from analog reproduction. Kudos to the father of AEo-Sound, Greg Wilsbacher at
the University of South Carolina, who scans a lot of 35mm newsreel negative
with AEO-Light negative VD tracks on his Kinetta.
