Dragon, Bruce Lee Story Help

[Master Yoda]

Right this disc is 7.92GB big, so i start by looking at whats on the disc, first off i decide im gonna strip out all 6 DD2.0 forien tracks.This removes about 1GB. But i found this...

I have'nt seen before.Im going to be backing up ' Dragon The Bruce Lee Story ' its pal.But this is the strange thing, the first half of the movie is interlaced, dvd2avi says its interlaced, and i can seeing combing lines, but half way through the movie it changes to progressive, dvd2avi then says its progressive and i cant seeing any combing anymore. How would i back this up.

Second thing, the video_ts.vob is about 400mb, ive open it in dvd2avi to see whats in it, and as far as i can tell all thats in it is the warning messages and about the first 5-8 minutes of the film.Why is there the first part of the film in this ??

I dont think demuxing by vobid will work as it changes at a cell, not a vobid. Cell id 1 -> 17 interlaced, 19 -> end progressive, not sure what happens to id 18 , dvd2avi did'nt show it.

VOBID 1 is Cell 1
VOBID 2 is Cells 2 -> 35
VOBID 3 is Cell 36

Also how do i strip that unwanted part of the movie from the video_ts.vob

Why is there the first part of the film in this ??

is it duplicated in the main pgc? either way its poor authoring. but when has a studio needed a good reason for that?

as for changing from interlace to progressive, it happens.. usually the changes are cut at chapters so demuxing by vobid will be the way to go. then you can process the progressive and the interlace vobids separately.


you can also do a avisynth similar to this--

video = mpeg2source("c:\.....")
progressive = video
interlaced = video
progressive = trim(progressive, 3000, 6000)
interlaced = trim(interlaced, 0,3000)
interlaced = fielddeinterlace(interlaced)
return(progressive, interlaced)

although ive never seen a progressive video hurt by the fielddeinterlace (like on hybrid stuff).. .. just run fielddeinterlace() on the whole movie.

EDIT
you replied fast.. i deleted my post and repasted since i saw no replies

if that part of the movie is int he TS vob AND in the movie vobs.. then just use ifoedit to strip

The only way i can seem to strip that video footage from the video_ts.vob is by stripping language units and id's .. is this right or is there another way of doing it.
Secondley i didnt really wanna deinterlace as ive read it cause's ghosting.
Is there any way to re-encode the movie by demuxing by pgc... ie. cut the m2v in half and encode the first m2v as interlaced and the second half as progressive then re-join the two new m2v's together.
As i said before, the change from interlaced to progressive is not at a change of vobid.
