I've been doing a reencode of an anime DVD. The source was partly progressive with an inregular pulldown pattern. about 89% film.
The way I've done It now:
1. Examining the raw MPEG2 frames ignoring the pulldown flags.
2. making a avs script that deinterlaced those Raw frames that was actually encoded interlaced.
3. Encoding the new m2v files.
4. Apply the old pulldown pattern on my 100 % progressive reencode using DVD rebuilder.
Now this works perfectly, but since I use a projector for most of the time I would really like all progressive playback.
As it is now however, since I copied the old pulldownpattern only part of the movie is progressive during playback.
My question Is what would happend if I ignored the original pulldown pattern. Making a true 24 fps mpeg2 stream without any pulldown flags. My guess would be that I would end up with out of sync audio since some of the frames/fields are supposed to be repeated. Is that so? :confused:
If this is the case, is there any way to put audio back in sync?
