FDecimate returning frames out of order
Posted: Tue Dec 23, 2014 4:49 pm
Hi,
I am using FDecimate as the first step in trying to improve a botched 8mm to VHS transfer (with no access to any other source material). The project was nearly done when I noticed a strange stutter in a few spots. I tracked it down to FDecimate returning a few frames out of order. I think this is caused by too high a threshold, but unfortunately the material is very noisy and there are some truly different frames with less difference then the average noise between duplicate frames. Still I would think it is always an error to generate out of sequence frames, and if anyone ever revises FDecimate it would be nice if this was prevented. (I recognize the need to serve up frames in random order might make this more difficult than it sounds). In the meantime, any other suggestions on how to decimate the duplicates? (I tried SRestore and SmartDecimate and FDecimate did a much better job than these tools once I determined the correct target framework by counting duplicates).
