How to patch an mpg video file...

[MiLToS_666]

Hello everybody,

I'm using my girlfriend's good-old Nokia Mediamaster 9600 to capture streams to my PC's HD. The Mediamaster is upgraded with the latest DVB2000 firmware and it's connected via SCSI with my PC. The program used to capture is called DVB2000 Recorder and it does it's job great!
Apart from saving the individual .mpv and .mp2 streams it can multiplex the video/audio streams on-the-fly and produces a ready to play .mpg file!

But here's my question...
Most of the channels don't transmit in full D1 resolution, for instance, ONYX.tv, a german music channel.
Here's the log from PVAStrumento after pressing the info button on a captured mpg:

***
*** PVAStrumento 2.1.0 RC6 build 85

Stream info for
E:\Temp\Schattenreich, 8-2-2004\Schattenreich, 8-2-2004.mpg

Found 1 video stream.
Found 1 MPEG audio stream.

VIDEO #1
Resolution 544 x 576
Aspect ratio is 4:3
Frame rate 25.00 fps
Nominal bitrate 15000000 bps
First PTS: 00:00:00.200

MPEG AUDIO #1
MPEG1, Layer 2
stereo, sampled at 48.0 kHz.
Bitrate 192 kbps
Each frame contains 24.0 ms audio (576 bytes)
First PTS: 00:00:00.176



Notice the Video Resolution: 544 x 576 ???

I just bought a DVD-RW and I want to start backing up some captured streams on DVD. The DVB to DVD-R guide is great but how can DVD authoring programs accept that mpg resolution? Is there any way to "fake" the resolution so that it's acceptable? But then... Will it be playable on my DVD player?

That's all guys, I'll be more than happy to have some answers! :)

Take care,

Hello !

DVDPatcher is useful tool to "change" (patch) resolution and bit rate of mpeg file. After this patching all authoring tool accept file as compatible (including real DVD GOP structure). But final DVD doesnt guarantee normal play in standalone DVD player, this is exclusively depending on DVD player (i.e. Pioneer 535 strictly requires standard DVD file structure without patching).

If you want to absolutely guarantee that your resultant DVD will be fully DVD-compliant, you might want to consider transcoding those streams with the unusual resolutions. There will be a slight loss in picture quality, particularly as regards colour space, and it is CPU intensive, e.g. a powerful computer (Athlon XP/Pentium 4) could take several hours to transcode the stream.

To transcode you can use either CCE or TMPGenc, my own favourite is TMPGenc, but many prefer CCE. There are guides on how to use both in this forum.
