VBR Frame Level SVCD Splitter?

[crimazine]

Anyone know of a vbr mpeg2 splitter that splits by frames? TMpgEnc doesnt seem to split at frame level and ends the audio 30secs or so before the video on split files.

I think M2-edit does that for you.

Or Womble MPEG2VCR

M2-Edit does not yet support VBR. WombleVCR demo wont open mpeg2. TMPGEnc claims ULead's MediaStudio will split but I found nothing that didnt require reencoding the file. Thank you for your suggestions.

you may try mpegtool. it's not 100%, but it usually works.

mpegtool works great! Thank you very much for the suggestion!

M2-edit for shure opens VBR-mpeg2 as does wombleVcr, maybe you tried m1-edit and the mpeg1vcr from womble?

Heh err mpegtool doesnt work as good as I thought, although it seems to work better than the others ive tried. Womble MPEG2VCR has an excellent interface but fails to TRANSPORT a usable file for me (powerdvd croaks on it) also filesize is questionable. Mpegtool creates a playable file (also filesize seems correct) on both powerdvd and standalone but doesnt make a very clean cut and chews up or leaves out the header in the 2nd half of the video I cut in two. M2-Edit does open VBR mpeg2 but specifically states that they dont support it on their website. I think DVD2SVCD uses bbMPEG to split its movies so I will see if I can get it to work for me.

With M2-Edit Pro you can do the edit. See the following thread:
http://forum.doom9.org/showthread.php?s=&postid=183711#post183711

But you should keep one thing in mind: MPEG2 is not MJPEG or DV, but just like DivX(3-5), a 100% frame-accurated cut is not possible.
Start at I-, end at P-frame will get accetable results(end at B-frame will get crappy frames).

MPEG Tool worked nicely, but, my mpeg-2 plays with time code, not frame numbers. How do I set the cut at the right place? Thanks. Michael

No way for MPEG-2 frame-cutting without new rendering like great authoring programs do!

Learn more about MPEG-2 encoding.
MPEG-2 is encoded with P-, and B-frames! You only can cut at I-frames - the begin of a GOP (Group Of Pictures). TMPGEnc, DVDAVI do so.

@Frank
Please read my last post in the following thread:

I've posted it sowhere above. But you haven't read it. Please read and build your opinion.

For more info about MPEG2 editing you can visit the german DVD/SVCD forum at:

or the thread:

and the post of shh

I've tested M2-Edit Pro 4.01 recently, it worked VERY exactly on MPEG2 streams, but not on MPEG1-streams. Perhaps I must use their M1-Edit Pro.

[frank]

Yes, I know M2-Edit Pro 4.0 and have tested a long time. That's one of the great programs I meant, and nobody owns.
It is able to cut on P-, B-frames because it can shorten or cut GOPs by generating the closing GOP frame.

But why this trouble??
For SVCD cuts into 2-3 parts you only need DVD2AVI.
Make separate projects for each part with demuxed/decoded audio. Encode, mux and author separated parts and you are done.

Another way is Avisynth with the Trim() command to cut the input stream before serving to the encoder.

[htc10825]

The Mpeg-Edit program was used to cut/merge the files captured by TV cards or recorded by the DVB(digital TV) cards on the PC.
To cut/split DVD-rip to multipol disks, the best method is to split them in avisynth. The way with DVD2AVI is not to recommend. The seek function in DVD2AVI is too inaccurate(every step with arrow keys will skip 3-10 frames, no way to go to frame# 12345 directly). With avisynth you can split the movie with frame accuracy, much better you can split the movie at the begin/end of chapters(use ChapterXtracter to get the exact frame number). Thus the change of disks is more acceptable and the quality of DVD-rip will be higher.
