I have a video in 60fps, i want to convert it to 4000 fps, so I am using twixtor. If I change the Speed to 33% it works fine, looks good, but what I really want to do is change the Frame Number so I can control the exact amount of frames in that video. When I select Frame Number I only see a frozen image, no matter if I set it on 4000, 60, 30 or 0. Am I doing something wrong? Any help would be gargantually apreciated.
