When to use IfoEdit and when not?

[sullen]

Okay. I just recently started doing dvd->dvdr with my Pioneer DVR-105.

Along the way I have burned several coasters and have learned some stuff from the forums and want to try to get some stuff straight. This is mainly concerning IfoEdit and the bug it has. As I understand it, IfoEdit has problem with movies that are encoded to 23.967 and use the 3:2 pulldown flags. I have had two movies that were totally messed up and I think that was the problem. They were Scorpion King and 12 Monkeys. I tried to use IfoEdit straight. So I am trying to find a way to determine what method to use so I can get it right the first time without having to burn a DVD-RW to check.

If I use DVD2AVI to check the vobs and it says the frame rate is 29.967 and the Video Type stays Film at 95 to 99 I have a movie that is in 23.967 with 3:2 pulldown flags to 29.967 and should use the DVD2AVI forced film, TMPGEnc 3:2 pulldown encode, and DVDMaestro process. Correct?

If I do the same thing with the frame rate at 29.967 and the Video Type stays NTSC through the preview I can simply use IfoEdit and burn with Nero. Correct?

If I do the same thing with a movie that is 29.967 and bounces from Film to NTSC in Video Type, I do None on Field Operation with DVD2AVI, 29.967 framerate encode with IVTC in TMPGEnc, and DVDMaestro. Or can I simply use IfoEdit on a movie that goes back and forth?

I have seen lots of posts here and there regarding problems and fixing, but none on determining which process will work everytime and how to make that determination.

Thanks.

I'll try to clear up the DVD2AVI issue with forced frame. I'm NTSC and dont use IFOedit or TMPGenc, but maybe this will help:

For jerking video, try the decomb filter pack, if you have already tried the correct settings in DVD2AVI and the pulldown command (basic) or with parameters hasn't helped. Try short test. DVD2AVI force frame is safe to use if it is 95% or higher showing film (checking a mid-movie voba, not the first one!)

The only way to know for sure if there is telecine is to demux in non-force-frame mode, and open in gordian knot. Step through frame by frame. If there's if you see interlace artifacts in 2 of 5 frames, you are looking at telecined conten.

So open up the .d2v without Force Film in Gordian Knot, and look around different places where there's motion. If you see the pattern of 3 progressive (not interlaced) frames and two interlaced frames (shows combing effect) out of every five frames, it's been telecined, and you can IVTC (inverse telecine.) If Force film can't handle it, try decomb.

If you find a mix of telecined and pure interlace, then Decomb's Mode=1 can handle it, although you will wind up with 30fps output.

Switching between NTSC and FILM by itself doesn't tell you much (except maybe that you can't just Force Film). You have to get in there and start looking at the frames.

That information is helpful, but doesn't lend a lot to my main question, only the third process that I am unsure what to use to make my backup. IfoEdit has a bug that messes up your movie when it is originally encoded at 23.967 and 3:2 flags are added during the encoding to make it play properly at 29.967. From what I have read if you run a movie that is less than 4.7gig through IfoEdit that is encoded this way to avoid re-encoding, your resulting burned DVD-R won't play past an hour or so.

As I mentioned above, 12 Monkeys fit the criteria where the movie was small enough just to run through IfoEdit and then burn. When I did this the movie was messed up just after an hour. When I ran it through the first process I described above, the movie came out perfect, playing to the end and with every chapter I put in DVDMaestro.

What I want to know is, does anyone have experience with what I have described and are these adequate ways to determine what method should be used to create a good backup the first time without having to use a DVD-RW.

I am going to experiment with the third process where the Video Type bounces back and forth and is interlaced. I am going to use IfoEdit and burn to a DVD-RW to see the results and if it fails use the IVTC guide on the DVD2AVI site that uses TMGEnc.
