Difference Between TMPGENC DVD Author and Ulead MF 2 ?

[StoneColdWhat]

Something strange has come up, I'm authoring a basic dvd using these 2 programs. First problem is with Ulead Movie Factory 2, an original 450mb file becomes 900 mb ( why? ) other then that everything works fine, the dvd would have no problems. When I tried TMPGENC dvd author the 450mb file would be detected as a 450mb file so I can fit 9 eps on the dvd where as with Ulead I could only fit 5, but for some reason the audio goes outta synch with TMPGENC where as the same files would be fine if I authored them with Ulead. Please help me figure this out

I use both.
MF2's only REAL good function is it's Edit Disc function....in my opinion.
Where did you get the material from to place into MF2? Is the audio AC3?

It sounds like DVD Movie Factory 2 is re-encoding your input files ... either the video or the audio or both.

I prefer to use TMPGEnc DVD Author and it does not muck up A/V sync so either your files aren't in sync to begin with or you are feeding it some "odd" files like MP3 for audio and it is converting it to AC-3 for you, or something like that.

What are the details of your source files?

That's not necessarily true. I've been using TMPGEnc DVD Author for over a year. Every file that I put in has to be split into clips of 15 minutes or less or the audio starts going out of sync. I've fed it hundreds of files, mostly mpg2. Some of them might have been odd files or already out of sync, but not all of them.

I have never ever had TMPGEnc DVD Author throw off A/V sync ... this includes importing DVD video directly into it (from a ripped disc) as well as my own encodings using CCE for the video and AC-3 files I created myself.

If TMPGEnc DVD Author is giving you A/V sync problems then there is another issue present that has nothing to do with TMPGEnc DVD Author.

I'm sure that's true. There's something in my system that causes it to get the out of sync. But I haven't been able to figure out what it is and I've been looking for a year. I even tried doing a clean install of Windows and then installing nothing but DVD Author- the problem's still there. It even happens with things I capture directly off cable.

For 10 months I just lived with the problem and split everything into short clips. When TMPGEnc's Mpeg Editor came out a couple months ago I found that if I run a file through it before putting it in DVD Author then most of the time there is no sync problem.

Sounds like maybe an odd multiplexing problem with your original source files. How are you making them?

I agree that's it's not TMPGEnc. I've done some RAM discs that were edited on the standalone using a few different programs, most of them had some type of audio sync problem when they hit the standalone edits, or just crashed completely at the edit points. TMPGEnc does them flawlessly.

Well I extracted the audio from an avi into wav using vdub, then I used that audio and did the converting with tmpgenc. Both the original and encoded files are in sync. Mmmmm I'm not sure where the conflict could be.

Some captured with a Snazzi III PCI card, some captured (months ago) with Studio 8 and a Pinnacle capture card, some extracted from vobs, some created by someone else on their computer and given to me to author. All had similar problems.

So you are feeding a DVD compliant MPEG file (M2V/MPV) and a DVD compliant PCM WAV file to both MF 2 and TMPGEnc DVD Author?

If so then how are you doing that exactly? What I mean to say is the last time I used MF 2 you had to feed it a multiplexed MPEG file and you can't multiplex a PCM WAV file with a M2V/MPV video file.

Unless there is a new update to MF 2 that allows you to import elementry streams?

Or are you converting your PCM WAV to another sound format such as MP2 or AC-3 ... then multiplexing ... then importing?

- John "FulciLives" Coleman

P.S.
There is an option in MF 2 called something like, "DO NOT CONVERT COMPLIANT FILES" and you MUST check mark that otherwise MF 2 will attempt to re-encode anything you input into it EVEN IF you are feeding it DVD compliant files. Even with this option checkmarked it will still re-encode if it detects that the input files are not really DVD compliant.

Well no I extracted the audio using vdub, then I loaded the original video with tmpgenc plus, then I selected the audio and encoded the file to .mpg. Then I added the mpg file to MF2, made the menu and began output. Same thing I did with TMPGENC DVD Author, didn't change any options/perference.

So after using TMPGEnc Plus to encode to a DVD compliant MPEG file you ended up with a single MPEG file with muxed MP2 audio, correct?

At least that is what it sounds like to me.

So here is what I would do.

Use TMPGEnc Plus to demultiplex your MPEG file. This will give you a M2V video file and a MP2/MPA audio file.

Now go back to the original PCM WAV audio file that you inputted into TMPGEnc Plus and convert that to AC-3 audio using say BeSweet or whatever (ffmpeg seems popular for this as well). Make sure this PCM WAV audio file is 16-bit 48k Stereo if not then you need to convert it to that before you convert it to AC-3 format.

Now try loading the M2V video file into TMGPEnc DVD Author along with the AC-3 audio file.

Doing that MIGHT fix the audio sync problem because after all MP2 audio can act a bit screwy sometimes on certain stand alone DVD players.

*** EDIT ***
If you no longer have the original PCM WAV audio file then convert the demuxed MP2/MPA to a 16-bit 48k Stereo PCM WAV file THEN convert it back to AC-3 format.

[StoneColdWhat]

Well I made a DVD Complient MPG before, added it to MF2, and it was totally outta sync. So I went back to doing vcd Complient mpgs and added it to MF 2 and it worked. Anyways back to the topic, I never knew you had to take an other step to convert demux the file and convert it to ac3... maybe thats why its not working, so I'll definately give your method a shot, but since I have to convert 8 eps it might take a while so please check back mid week FulciLives, and everyone who has ideas to solve the problem.
