forty-two and 3:2 Pulldown

[KaiCherry]

I have rebuilt the forty-two engine to set 3:2 pulldown flags.

I *believe* because of the way forty-two works, this *might* actually sync...but I wouldn't let up a woop of cheer just yet.

I know in mplayer, it has an *annoying penchant* for pausing slightly during the preview playback when these flags are present, since the pulldown stuff is basically designed for settop hardware.

After I finish the PAL testing I'm doing, I will make a VCD set with this and see how it works out. I will be testing it with my software players and my Pioneer settop box, since its the only standalone i have that will play VCDs.

Depending on how it goes, I will make a determination as to if or not this is doing more harm than good overall.

I would love to test this for DVD to DVD-R, and see if it clears up the jerky video issue I am getting form Forty-two, which I think it will. I am not concerened about other formats like svcd or vcd, just DVD. I can give her a go if I could get hold of a beta version.

DiscomVOBulator is your solution!!! This thing is awesome. I'm surprised that there is little discussion on this forum about it. Is it because it costs $25? QT mpeg decoder for another $19?

I see people on this forum not getting it. Discom doesn't retain menus, chapters, etc. You put in your own chapters. It copies the title track and automatically splits the movie across two DVD-Rs in about two hours. Not a day and half like Forty-Two. The only negative thing I would say is the video pauses slightly where each chapter is. Other than that, Discom is fast, high quality, and compatible with more DVDs than 42 has been. Discom really works!!!

We haven't seen this on *any* players...what are you playing back with?

TIA,

Panasonic DVD-RV32

It was one of the models Apple had on their website at the time. I bought this just to be able to play DVD-Rs. I have a much nicer Marantz that won't play recorded disks.

Actually, Discom solved the jerky video I was having with this player (except for the chapters). Seems Panasonic players have some issues with Forty-Two DVD-DVDR disks.

In the meantime, I'm not using chapters. If I watch a movie, I watch all the way through.

Ok...this isn't going to happen

Sorry...the results are *HORRIBLY OUT OF SYNC*

At least you're trying.

LOL..very simple game. If it causes sync problems on everything I try it on, then it ain't going in forty-two. YMMV

It is very pleasing to know that ya'll are continuing to work and refine the program, and are attempting to add the features people are begging for.

I am sure it is a good app, but I am not interested in having a movie on 2 disks, I was disspointed when I bought the extened verion of LOTR and found out it was on 2 disks, I guess it is ok if you have a multi disk dvd player, but it sucks to have to change the disk part way through a movie.

it is to bad that this did not work for you, I thought it would be the solution to the problems I have been having with Forty-two and jerky video playback.

Was the sync out just on the VCD you made or did you try DVD-DVD and get out of sync?

Its sucks even more to wait untold hours for a lower-quality dvd that has no features *at all* that makes a DVD a dvd

Its your DVD player. NTSC Film is a perfectly valid and legal format and DVD players are supposed to play it back correctly. All of mine do, as well as my buddy's ps2.

The NTSC Film framerate of 24fps is only valid in the VCD spec. In DVD when you have 24fps material (aka "progressive"), the stream has to include those 3:2 pulldown flags yielding a simulated 29.97fps output. In DVD Studio Pro, for example, the Import option won't even allow the addition of 24fps MPEG-2 without those pulldown flags. Perhaps whatever engine that makes the burnable disk image from 42 is set to ignore the requirement for 29.97fps in NTSC content. If so, any burned disks would not be compliant.

This is why it's important to also have a copy of the elemetary streams from these encoders ... just in case you need to author them properly by hand. To start, you'd need to run your m2v MPEG-2 video file through PulldownX to set those 3:2 flags. PulldownX doesn't re-encode the video ... just adds the flags.

I agree Io would like to be able to choose between an iso or elementry streams.

PulldownX sounds like it does the same thing as MPEG Telecine, just drag and drop the m2v to the app and it adds the flags. This only takes about 2 minutes.

[KaiCherry]

Wellll...yes, and no

If you have progressive scan, this is all kinda rendered moot. Whats more, it makes no sense that some players seem to 'do the right thing" while others do not.

You find me a *nix tool that does the pulldown flags, and its in. As it stands, doing this with the mpeg2enc encoder yields results that are completely unusable and is a *root cause* of sync issues since the actual stream isn't ntsc video in the first place.

Otherwise, it stays the way it is.

found what i need. if i can integrate it and it doesn't cause sync problems then look for it in the next version, probably in a week.
