all mpegs out of sync after authoring

[nick101181]

For the past month or month and a half I've had this problem. All my mpegs are perfectly in sync before authoring to dvd, but after they are out of sync. I've been using tmpgenc dvd author, so I switched to ifoedit. It doesn't matter what program it is, I always have the same results. Most of my mpegs are dvb mpeg2 capture, but I sometimes have mpeg2's from my wintv pvr 250 card. Is this a directshow problem or something else? I tried running the video thru videoredo and it fixes it, but it seems to take a chunk out of each mpeg and replace it with mass swirly pixelation. I've always taken my dvb mpeg2 captures and patch then with dvdpatcher and author in TDA and have always had perfect results, also the same with my wintv pvr mpeg2's. I would really like to get this figured out so I can author and burn off all my mpegs off my harddrives.
Thanks

Have you tried PVAstrumento for clean up ? Might be worth a try. It really sounds like there are issues with your source material, first and foremost. As for kludge solutions like patching headers - you pays your money and takes your chances

Well I've tried pvastrumento and that never worked. I'm thinking it's something I installed a while back. The source mpegs have never had anything wrong with them. I always authored my mpegs in TDA and they worked perfectly. All my mpegs are in sync prior to authoring. For the past year and a half I've been just patching the headers and authoring and all has been well. Even for my vhs to mpeg2 captures that I didn't need to patch the headers they were always in sync as well. I noticed it's a recent thing. I'm wondering if there is a way to totally unistall all codecs/directshow stuff then try everything again after?

System Restore. Drastic, but it works most of the time. The issue is working out when things went pear shaped.

1. Try projectx for demultiplexing/cleaning
2. Try to use a raw dvb recording format (transportstream = .ts)

You are probably dropping video frames on capturing. You need to find out why you are dropping frames. Bad source? Capping from video tapes? Computer running other tasks?

When you drop video frames, the capture program pads the capture, which keeps everything in sync. Once editing or authored, the padding is gone, which is why it goes out of sync.

It has been confirmed for a while now that TMPGEnc DVD Author can cause perfectly normal MPEG files to lose a/v sync for no apparent reason. Most people will run across this error, in any version of TDA, if they use it long enough. At this point in time, it's considered a random error. I know somebody who used TDA for more than 1 full year (and swore by TDA) before he saw any problems, and out of the blue, it plagued at least 5 of his DVDs (now he swears at TDA). The fix was to use something else (Ulead DVDWS is a popular choice, more advanced but still just as easy to use).

A/v sync loss can be caused by any number of reasons. But be sure to consider this TDA flaw early on in your list. TDA has a LOT of flaws, keep that in mind when you use it and see authoring errors/oddities/imperfections.

In this exact case, it's more likely the DVB files. Those are non-standard MPEGs, and are known to have problems. I would suggest using VideoReDo as your editor, and then using the MPEG repair tools it offers to correct the stream.

I also tried IFOedit to author a dvd but it was also out of sync again. If I reinstalled directshow would it fix my problem perhaps?

[nick101181]

I tried some more videos from different source material and they are still out of sync. I converted 3 avis to dvd mpeg2 using tmpgenc, then authored them with TDA. The first file was in sync but the other two weren't. I've got no idea why every mpeg on my pc,even if the source is perfect or not, is out of sync after authoring. Is there anything I can unistall to fix this kinda thing? I would really like to know because it's driving me crazy. In two years I've never had to run any of my encodes or captures thru mpeg fixing software before.

Thanks

Only reinstall I've seen that really helps is wmplayer 10, to try and get basic windows stuff as it should be. Unfortunately if the files in windows have been updated by other software, sometimes hard to get the versions you want to over-write. It is possible to go backwards, get rid of whatever direct show filters and reinstall, but to do it thoroughly can be a large hassle.

RE: sync issues, are you joining the files, or do individual files once authored go out of sync.? If you're joining them, could be length of audio not matching length of vid, so when everything butts together, everything after 1st vid is out.

If individual video is out of sync once authored, could it be mis-setting audio or video delay?

[nick101181]

All the mpegs I use for authoring to dvd are single files. Most are mpegs that are around 4 gigs or 3 gigs or so. Occassionally I'll have an mpeg that needs a little shrinking down but Not that often.

@lordsmurf

You are like a mind reader, TDA has worked perfect for me for months and months then out of the blue i was getting out of sync problems with it, could not get rid of the problem even after restoring a ghost image where TDA was working great.

I really believe TDA has code in it what messes up the program after x months to make the user upgrade, i know it sounds silly but i can not think of another reason why the program just went pear shaped.

Moved over to DVDauthorGUI and never had a sync problem.
