Hi, I have a video I demuxed from a mkv, the video file is suppose to be 23mins in total but fast forwards and is at 18mins after demuxed from the original mkv it was in.. I already have VideoDub and AviSync installed, I would like to know how to sync it to it's original state please..

Edit: Well I found out the video is encoded with 29.97fps, but how would I know what fps to encode it at so I get a smooth running video? Does anyone know how to find out the decimated fps?
