View Full Version : 85% film, pulldown removal. What would happen?!

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?

Is that so?
Yes.

If this is the case, is there any way to put audio back in sync? A 20% squeezing of the audio is unlikely to be tolerable.

it's been awhile but i'm not sure I see how the pulldown pattern would effect what your doing exactly.....

24 is also not a valid framerate for most authoring apps... NTSC requires 29.97

Not sure either that the Big3 forum is the best place for this question.. seems your using Rebuilder
