Black Hole
May contain traces of nut
I've used a video grabber to digitise the output from a VCR. The resulting .mpg plays the audio OK, but the video is sped up (maybe double?), in both VLC and VideoReDo.
MediaInfo says:
What stands out is "Scan type = Progressive". It should be interlaced! I guess that would double the frame rate if fields are taken as frames.
Anybody know some magic I can use to change the scan type info?
