Problems with an interlaced movie.

[stangyamahar1]

So i tried to backup my copy of possession and it is reading as interlaced in DVD2AVI. I ripped the movie using dvd decrypter, then loaded dvd2avi and chacked out the stats and saved with "no forced film" I then reencoded it using cce and now when i bring it into maestro it is like 30 minutes longer than the audio? Whats the deal? I tried all kinds of different pulldown commands, but none seem to work., every pulldown file is always longer. I tried compiling the movie without doing the pulldown and it is all jittery weird on playback. Any help would be appreciated.....

"no forced film"

This will set the frame rate at 29.97 in DVD2AVI assuming the film is NTSC. If you are running pulldown on the encoded .m2v file you are actually increasing the frame rate to 36 which will increase the length of the video substantially.

You only use pulldown when you select "forced film" in DVD2AVI which gives a frame rate of 24. Using Pulldown then inserts flags into the stream to tell the set top player to run the film at 29.97.

Ok, so i still have no clue, what to do. The film is ntsc. So does this have anything to do with the interlaced film? I just need to figure out how to get it to work.

damnim thanks for the help, but you did not really answer my question, I can backup any other movies jsut fine, but they are all proggressive, i just need to know what settings to change, and where, for an interlaced film.

i did possesion a few weeks ago bit of a stinker first 5 mins is telecined (up to point it cuts from him reading the letter he finds in the book to the chap writing it years before) then it reverts to pulldowned progressive, an ocassional second or so of telecine pops up now and then (not too bad) but then it sticks a few more telecined scenes in further on (the scene with victorian train journey thru to where they're at waterfall)

I ended up saving dvd2avi project with forcedfilm off, IVTCing it with TMPEg (auto settings will do the telecine pattern used is basic and repeats throughout)

to produce 23.976 NTSC film version at high bitrate cqvbr and then fed that into CCE

If you want the movie on a disc at reasonable bitrate then you could probably modify that to tmpeg it to a 23.976 progressive final output file and just run a pulldown on that before tkin it into maestro

I only went the twin encode route as I needed a highly compressed version as my final cut and CCE - (even when working on a bloated tmpeg initial encode) produces a much better highly compressed version than trying to have tmpeg compress to that amount itself.

Just to complicate it a little further my final output is PAL conversion which made getting a clean 100pcnt progressive output all the more important (as I could then just speed it up to 25fps and adjust audio to suit)

to be honest though if you arent wanting to squeeze it to point it'll fit as part of a multimovie DVD/convert to PAL then lot easier just feeding it to either DVD2one and abandoning the extras & menus, or feeding it thru Instant copy and keeping the extra bits n bobs - either of those will duplicate the original hybrid stream and bypass the issues completely

When I was writing the post I was thinking to mention something that I keep running across that snorkel64 pointed out which is different encoding methods in different sections of the movie.

The studio intros are usually different then the rest of the film. I find they are interlaced while the actual movie is progressive. Now if you run a program on the stream to determine its charactaristics it may tell you the whole film is interlaced when in fact only the studio intro is and the rest of the film is progressive.

Now the stinker. I have found some movies with an interlaced intro, a bottom field first progressive in the first couple of vobs and a top field first in the remainder. What to do?

You have some choices, frameserve the entire film through dvd2avi to guarantee the frame rate at 29.97 by using "None" under field operation, in CCE don't select progressive or top field first and cross your fingers that it works. Field order can cause the biggest problem because it will create a choppy picture if incorrectly set. If after running a program on the stream to find its' characteristics you find top field first then set it that way and vice versa in CCE.

Another method which I use on problem video streams is to shrink the entire video after using ifoedit to strip out all the nonessentials from the ripped DVD with a program like DVD2one. Doing it this way doesn't alter the original video stream in any way just makes it smaller. I have had great success using this method and it only takes an hour instead of 3 or 4 using CCE with unpredictable results. Again, I want to reiterate that I strip out everything except for the video stream and the audio stream that I want.

Thanks for the info. SO everyone recommends this DVD2one program, how much is it and is it worth it? I really don't care about the menus, extra features, etc. Mainly i just want a backup of the movie, for viewing. I have loaned out to many of my originals and get them back all scratched, or worse, lost. I think i will try the demo of DVD2one and see how the 30 minute trial thing looks.
