repairing gop length of dvb mpegs?

[nick101181]

I need some help on this. I've tried every method and every prog to try to do this successfully. I ended up figuring that womble's mpeg2vcr was the best after testing videoredo and a bunch of others. Now here's the big problem: Doesn't work with large mpegs at all. I tested a 945 meg dvb mpeg and it fixed the gop correctly and the audio was perfectly in sync and everything. The other mpegs were over 4 gigs each and the results was out of sync all over the place and here and there thru the whole file. That's too much of a pain to fix. My only solution maybe it to tell mytheatre to split my recordings from now on to 900 megs each or something. I'm not sure if they will join correctly after. So how could I fix the gops on these large files I have now? Ignoring the error in tmpgenc is not an option for me because if the files have a correct gop then they play in my dvd player fine, it not then I can view them but loose all functions and have to power down manually. any ideas? I've thought about encoding the dvb to xvid then back to dvd but that would be a hassle. thanks

Without re-encoding? I don't know any other way without some lipsynch probs (or other issues).
Sorry....

thanks satstorm. I've also tried re-encoding but that was out of sync also when using dvd2avi to make the d2v project. I'm thinking the problem is the mpegs are so long. Some are 3 hours and 4.5 gigs or more. Maybe If I tell mytheatre to split them up to 900 meg files each then It would be easier to edit. I'm gonna try dvx also and see if it re-encodes to a high quality xvid that I can re-encode from also. mpeg2vcr worked fine for one of my mpegs that was 945 megs. I wonder why it worked for that and not the big mpeg. First I'm gonna use dvtool to split the mpeg up into smaller sizes then correct the gop one each split file with mpeg2vcr then I'll post my results.

try load it to virtualdub mpeg 2 and frameserve it from there...

What I guess is that theatre drop some video frames to lock to audio and when you re-encode / cut it goes out of synch... I believe virtualdub mpeg 2 could help you with this...

[nick101181]

thanks satstorm, I'll try this next. I just tried to split it up into like 7 parts with dvtool. I was getting happy cause I thought it was in sync but it was only the first file cut that was in sync. Now I'm gonna try your method to see.

I'm having problems frameserving now to tmpgencplus and cce. I would really like to frameserve it to cce since it's faster. I saved it as tp.vdr.avi like I usually do when I'm gonna frameserve to tmpgenc but says invalid or something. I've frameserved before to tmpgenc, wonder why it's doing this ?

[nick101181]

I've found the solution. Tmpgenc has an mpeg editor now. I loaded it with it and just outputted it again and it's in sync and now I don't get the gop length error in tmpgenc dvd author. I recommend this product to everyone. It did what womble mpeg2vcr couldn't do : an almost 5 gig mpeg in sync. thanks satstorm

@ nick101181

you missed a step, that's why your tp.vdr.avi file would not load.
vdub does not open .tpr files (from TMPG) directly. YOu have to open it
in VFAPIConv.exe and create a psuedo AVI file - only takes but a few seconds
to do. Then, you can open this inside vdub or cce or procoder or whatever
Encoder of your choice.

I forgot to install the handler ever since I had to do a fresh install. Now everything works fine. Thanks. I like the file that tmpgenc mpeg editor outputted but my wife thinks it's offsync not by much but a few milliseconds not even 10 ms. I seem to think it's perfectly in sync. It's just when certain people talk or move their lips alot it doesn't look like it's in sync. Has anyone with Mytheatre ever used the split file while recording option? it says it splits it then overlaps 5000 ms. Would this be a good option to use or would it put it out of sync as well

I've had some success fixing GOP errors with Project X; there's never a sync error with this program.

[nick101181]

I'll give it a try. I have noticed now that after authoring tmpgenc mpeg editor was offsync and quite a bit. Seems to work fine with smaller file sizes though.
