Womble, audio out of sync

[2000a]

I am experiencing a problem:
- when i author (VOB) an MPEG2; the sound and audio are in sync. this proves that my authoring software is good.
- when I cut parts from the same MPG (2) file (with Womble 3.14), the actual MPG file is OK when played on windows media player, when authoring it to DVD, the VOB's audio lags (2 seconds).
- if i use TMPGEnc to cut the same parts, the MPEG and VOB's are OK, in sync... TMPGEnc takes 45 minutes (instead of 6 like Womble)
- this happens with all the MPEGs i've tried. The out of sync audio/video, normally happens after 30 minutes...

Any ideas?


thanks

I'm a little surprised that TMPGenc works.
I think you got your mpeg2 from a DVD right ?
The video is probably NTSC Film which has soft pulldown
Womble can't seem to handle that . Neither can TMPGenc usually.

I have been looking for a good solution to this for years.

Actually, my MPEG2 doesn't come from DVD. I captured it (using a TVTuner).

I think Womble 3.14 was released back in February and a new build is released at least once a month, if you go to help/about it will show the built date, I read that newer is better (one from August or September will be OK).

my version is 08/2003

any other ideas?

What tuner and what capture software ?
You may have dropped/bad frames

[2000a]

IT is not related to dropped frames. the mpeg is fine if i author it to DVD (VOB). the problem is with womble, when i remove comercials from my original MPEG or when I cut a part from the begining/end of the MPEG and save it. in one case, the actual mpeg that was created by womble, was out of sync (when playing on media player).

The MPEG created (edited) by TMPGEnc has no problem when authoring to VOB!!!

I am having a similar problem with Womble 3.14 (date september 2003). Every time I use womble to remove parts of an mpg and author a dvd using the edited mpg, it does not play back properly in my stand alone dvd player. I get choppy video and the audio cuts out after a few seconds of playback. I've even had it lock up my dvd player.

If I take the same mpg without editing it and author a dvd, it plays back fine. Womble is doing something to the mpg that is causing problems with my dvd player.

I have a Pioner 525 dvd player. The video was captured using the WinFast PVR software for my Leadtek WinFast TV 2000 capture card.

by the way, the audio sync is only an issue after about 30 minutes. If I cut every 30 minutes, it authors without sync problems. It is weird because if I only cut at the end (2hr clip), the audio will be ok until I get to about 30 minutes, then it gets out of sync by 1 or 2 seconds.

If I play the edited MPEG2 file, it doesn't have the sync problem.

If I author the (womble) edited MPEG2 file, the sync is there after about 30 minutes.

If I author the original (not edited) MPEG2 file, it doesn't have the sync problem.

Any ideas?

I am thinking of trying Cyberlink PowerVCr II 3.0... Any comments?

thanks

I did a good deal of testing with Womble a while back
and what I found was that I couldn't break it unless the
video was soft pulldown NTSC film. I generated the
test cases with Avisynth (so I could see frame number) and
an IVTC capture with ATI and an IVTC done with TMPGenc

In those cases the audio would get a fixed amount out of sync
on every splice. I can't remember how much - maybe two frames worth

Another case that was worse was a captured movie where the
movie was Film and the commercials were 30 fps
I could edit fine until I did the IVTC.

I don't think that's your problem - you don't have a soft pulldown movie
so I dunno

Well TMPGenc DVD Author program 30 day trial (Link on left) will let you cut out commercials and start/ends

once in a blue moon it looses synce on one segment of the cut, but generally works very good.

Good luck

I am having the exact same problem using Womble but not TMPGEnc! I capture using ATI-7500 AIW to the Video CD format. Then I go in and cut out the commercials and save the clip and the sound is off by a LOT! What am I doing wrong here?

I'm doing everything in MPEG1 and all files are captured from the ATI card. I would love ANY help!

Well i had some probs with some dvd mpegs but i scan with womble for errors and fixed those errors with it and it went fine.

I never had a simply problem with mpeg2vcr (same version 3.14). Maybe this is an NTSC thing? I use PAL.
The only iritating bug I have, is that each time I cut something, I have to save it and then re-open the original file to cut a later part...
Also, by traditions, I always let the video "roll" a bit in the start, before I push "record".

[FOO]

Sat, why do you have to save and open it again. What happens
if you don't ?
I just mark-in and mark-out around a section and hit Cut.
Then I move the pointer and do it again.

[SatStorm]

The source file, doesn't have audio anymore!
It is a common problem to Athlons, never pop up to Intels! But on intels, you have lipsynch problems if you don't re-open the source file. It is a silly bug...
The reasons for this, can be anything: Audio drivers, Mobo chipset drivers, whatever... You never gonna find what it is, even if you search hard for days! So, better re-open the file, which after a while won't bother you as an action so much, and do your job. It is faster than to try to find days how to fix it. (and to find a solution which on a later hardware may not working again....)
I know many womble users doing this....
