tmpgenc only sees partof mpeg

[wackynige]

please help. I have a good quality SVCD on two disks. the second disk skips around abit and near the end just freezes. I want to fix it and do not have the files apart form what is on the svcd.
I have run the mpeg2 through mpeg corrector, vcdgear etc. Iwant to try and mutiplex it again but when i do it with tmpgenc it only does the first 4 mins before it says it is complete. i tried demultiplexing but the same thing happened. please help me.

Sounds like its hit the error and cannot process it this way, you may need to load the mpeg back into TMPGEnc and re-encode the whole thing again, in the hope it will handle the error.

Ok that sounds like an option, can you be a bit more specific and tell me how to do that. do i need to take the MPEG2 file form the svcd cd first.

I have run the mpeg2 through mpeg corrector, vcdgear etc.

If you have already done this and now have a .mpg, if you have the 30 day vertion of TMPGEnc you may have problems loading the SVCD mpeg, along with some missing codec which would be installed with other programs that play Mpeg2 files.

Yeah. the second link talks about demultiplexing but i treid this and it only done the first four minutes and then said it was complete. I did do this from the CD however. are you saying i need a full version of tmpgenc to do this.

You have to stream copy it to "bump" past the errors. There should be no need to re-encode unless the error lies in the audio track.

Load Tmpgenc
choose File>New project (this "blanks" any pre-loaded settings)
Load the mpeg2 file
choose File>output to file>mpeg file

Ok tried that and it freezes at 25% on a very blocky frame.

Make a note of the source time (left side top) and then open file
again, choose Settings>Advanced>Source Range and select the
1st (24%) part of the film a few seconds before the damage. Encode. Then do the same but select a few seconds after the damage. Encode
Use MPEGTOOLS under File and choose merge/cut to merge the
two (or more) mpeg files back together.

If this fails u are going to need to load the movie into Virtiual Dub, fix
frames, save as an AVI and transcode the whole movie again under
tmpgenc.

check this link: http://www.vcdhelp.com/tmpgenc.htm#problems

will try that thanks. virtual dub option is out as i get a pack syncronisation error when i try and load it in to VDub

[KingJohn]

Trouble is TMPGEnc has to load the movie from the beginning even when using the source rage, it streams the file until it reaches the part you want to start from, if it hits an error it can still falter on the bad frames.

Perhaps a different version of TMPGEnc may help, when a new version comes out sometimes the older one is better for different things.

I found the new version better at handling bad frames, but there again its usually AVI not SVCD I use

Open the mpg in dvd2avi then save as a project. I have found dvd2avi opens just about everything but if it doesn't I think you're screwed. Open the project d2v file in tmpgenc and reencode to svcd template of your choice. This encoding will be slow but should fix the problem.

ok done first 25% in tmpgenc but it did not fix the blocks. so no point doing the rest really. as i said it wont load into virtual dub for some reason I get a pack syncro error.

Are u using the vcdgear file? If so try the uncorrected file. vcdgear
sometimes really stuffs the original file up.

[wackynige]

the uncorrected file is still on the svcd as when i try and copy it to hard drive it comes up with an error right at the end.
