Fix Fields

[xpavement]

I am working with some analog NTSC captures to huffy, resizing to 352x480, and encoding with CCE Basic for DVD. I am trying to keep the files interlaced, and I setup my templates using the doom9 guide here:

http://www.doom9.org/mpg/ccebasic.htm

Recently I got a new os drive, and I had to remake my templates, but I forgot to change the offset line in CCE from 1 to 0 for my interlaced templates. My footage was top field first, so encoding the video and placing on a dvd makes the resulting video slightly jumpy.

I do not have the original source, just the incorrect mpv and mpa files from CCE. Can I use AviSynth/DGIndex to fix this file and re-encode? Or is there an easier way?

Short of changing the TFF flags throughout the MPEG file, you can change the field dominance by either chopping a field or using Simon Walters's filter. You'll be able to get the video in the right order, but it won't fix the MPEG file.

If you want to fix the MPEG file you should try shh's ReStream. With it you can switch the bff <––> tff tag inside the MPEG file. The resulting file will still have the motion vectors in wrong direction, but at least it should play fine!
