I am looking for a Windows tool that can convert the framerate of an avi video file. Basically I want it to play at 4 times the speed.
The video itself should technically not really be 120fps but still 30fps. It should just resample the source video so that it seems to be playing at a speed which is 4 times as fast, which should result in the same effect as playing the original in 120fps.
I tried using VirtualDub, but it results in frozen frames every 5 seconds for about 1 second.
