When I use my Canopus ADVC 300 to digitize a 24fps video that's been converted to 30fps, I get a DV file that needs yuvkineco run on it in order to reverse the telecine. Experience has shown me that I need to pipe the video through "yuvcorrect -T TOP_FORWARD -T INTERLACED_TOP_FIRST" before sending it to yuvkineco. Experience has also shown me that I need to hand-edit the file produced by yuvkineco (i.e. the one written by the "-C" option) for maximum quality. But that means I need to look at the top-forward version of the video in order to resolve ambiguities.
Attached to this letter is a bash script that I use to do that top-forward
correction on a DV file. Is there a direct way of doing this to a DV file?
The file produced by this script can only be used for review, i.e. since
there's a DV->raw->DV conversion, I don't want to use it for actual video
generation.
If there was a direct way of doing top-forward on a DV file, I could save a lot
of space and time. Does anyone know of a way?
