why the hell does tmpg & tmpg plus not fully encode m2v

[mazinz]

i know i have seen this mentioned a long time ago but i was not able to find the post for it.
Can anyone tell me why the hell tmpg NEVER seems to fully encode your m2v file? It says it is at 100 and it stops but yet its missing like 20mins of the film at the end. Hell even when i set source range it still does it. I even added in an audio to try and help things with no luck (that used to fix it) but now i have one film thats split between 3 files because of this crap (and it still f'ed up so now i will have 4 files for it). Sorry but i am highly frustrated at the moment. My old method of using the audio with it seems to have failed. The versions used were tmpg 2.56 and tm,pg 2.5 plus. thanks

Have you scanned the source files for bad frames?

I have never encountered this problem with good source files

Is the m2v demuxed from DVD vob files?

[mazinz]

yes it is demuxed from a vob file (i was doing a pal to ntsc transfer). Ironically i did solve the problem using one method. I used dvd2avi and had made a .d2v file. This worked fine, and tmpg encoded the entire film like it was supposed to do. But i am still curious why it did not fully encode it to begin with, when i had just dropped the actual file in it?

Hmm i would not trying to scan it for bad frames, which tool would you suggest?

I was thinking of downloaded avi's for source files. if they are from DVD source, don't worry about it.

You have VOB extras in the file. It needs to be demuxed back to a base MPEG file. Use VOBEDIT or demux at rip.

hey lord smurf
i went through the film various times, their is nothing extra in the m2v file at all . It is just the film. i used dvd decrypt to demux the m2v from the disc.

I've directly converted many vob's with TMPEG. The problem is caused by what's called a Program Time Stamp in the vob file. When TMPEG encounters a PTS it interprets that as the end of the file and stops encodeing. I can only guess that a PTS survives the demuxing and stops TMPEG. I find that an m2v file will usually stop encodeing midway in the file if it's going to stop.
The DVD2AVI method will always work and most people use that method.

The use Restream to remove the PTS if Decrypter did not do it (odd).

TMPG is now using built-in CRI Sofdec decoder to decode mpeg1/2 files. I had similar problems with mpeg files. After I lovered priority for Sofdec and installed Mpeg-2 video plugin everything worked just fine.

[mazinz]

but what was interesting is even the older version of tmpg (where you could still use mpeg 2 and ac3 audio with no problems), it still did it. But the d2v file method worked fine, so i might just be using that on the rare occassions when i actually do have to encode a file

[mazinz]

hey here is something somewhat off topic but related to this. After doing the whole d2v file thing, it played fine on the pc, but on a homedeck machine the film had that "double letterbox effect" (dark bars about 2 inches on top and bottom, with lighter letterbox bars for the 2:35;1 pic on the inside). Knowing the film should not be like that, i tried that mpeg2 pluggin mentioned in one of the above post. It worked like a charm. Did the whole film and it made it display as it should have been while keeping the 16x9
