TMPGEnc cannot open mpeg files from DVB in mpeg tools

[misiek]

I use to record satellite programs on hd using a DVB pc card and viewing program progdvb. Format of recordings is mpeg2. Anyway when I have to cut commercials and I try to open such files in TMPGEnc mpegtools (Merge and Cut options) program cannot accomplish the job and returns message "illegal mpeg video stream". Maybe have I to use a suitable plugin? May you help me with this stuff? Thank you very much in advance.

Sticking to what I experienced with my DVB-card and what I read about others, records from DVB Cards are normally done in pva or ts format, even when the extension of the file ist mpeg.

PVA or ts are similar to mpeg2 but not(!!!) the same.

So you need to convert your records first before editing them for instance with tmpgenc.

Take a look at

for pva strumento (used by dvd2svcd for instance)

or

for the open source Project X (german page).

To be more exact:
- PVA is a container used by DVB applications to improve recording, and it contains MPEG-2 streams. This format is not covered by the MPEG-2 specs; you can view it as an extension.
- MPEG-2 TS (transport streams) are in fact part of the MPEG-2 specs. There are elementary, transport, and program streams.

If you have the choice, record in PVA format, then correct the stream and extract the elementary streams (I use ProjectX). MPEG2Schnitt is a very good program for cutting elementary streams (video + audio incl. synchronizing), but it's in German (not frame accurate, but better than GOP accuracy). You may also use PVACut to cut at the PVA level (GOP accuracy), and use ProjectX afterwards.

Thank you very much to everybody, really! I've seen that TPvrConv by Talpa and Nanide and Vidomi can accomplish cutting of mpeg files produced by ProgDVB. Also MpegCut does the stuff. Normally I record in mpeg format, but I have the choice to record in pva format, too, so I should have a little question. Why is recording in pva format better? Can I have errors when I record in mpeg mode? May you explain this fact? Thank you very much in advance.

The great better-than-GOP-accuracy cutting software MPEG2Schnitt is available in English now. See Doom9's downloads.

Thank you for reply. I've downloaded English version of mpegschnitt (I don't understand German) but I'm not able to open .mpg files produced by progdvb, I don't know why... With TPvrConv or mpegcut I can. It seems program isn't capable to see them.

MPEG2Schnitt needs elementary streams to operate. So if you have a program stream, you need to demux first. You should do this using ProjectX (x08.jar) or PVAstrumento. Both programs not only demux the file, but correct the stream, too, which is important before proceeding.

The elementary streams can be opened in MPEG2Schnitt (it openes the audio stream automatically as soon as you open the video). The program supports AC3, too.

Thank you very much, bb, I'll try everything.
