If you know how to use
PhotoShop then it is fast doing same thing as
Automask=1: save dark frame, load it into
PS then with Levels get mask, but if you already have black frame then there is no point wasting seconds/minutes with external programs when you will have same in milliseconds with
Automask=1.
If it is only
InpaintDelogo in a script then MT slows down encode. Very quick test, very slow x264 settings (1000 frames):
Code:
Only InpaintDelogo / Prefetch(4) - 12fps
Only InpaintDelogo / No MT - 16fps
InpaintDelogo + other 3 heavy filters / Prefetch(4) - 10fps
InpaintDelogo + other 3 heavy filters / No MT - 5fps
We can see that MT fps increase on other filters outweighs fps loss on
InpaintDelogo here, or whatever MT does, I'm not an expert on that...
If it crash with Prefetch(4) then use 64bit. Or you can try Prefetch(3).
