Joining MPEG2 Recordings?

[betbest1]

Does anyone know of a freeware program to join MPEG2 recordings? I use VirtualDub-MPEG2 to remove commercials and convert to XviD, but it cannot join multiple MPEG2 files.

You can use VideoRedo, but that will cost money...

You can actually butt up two MPGs together. So a DOS command that copies two files into one will work.

Or use this tool..mpgtx.exe which is part of the ComClean package from the wiki...

I use a command like this:

Code:

"c:\program files\devnz\gbpvr\mpgtx.exe"  -j "File1.mpg" "File2.mpg" -o "Destinstion.mpg

That would be:

copy /b file1.mpg+file2.mpg[+morefiles.mpg] > destination.mpg

the [+morefiles.mpg] is optional of course.

You might not want the ">". And the part where the videos are joined is kind of colorful, plus the times are messed up. I'm going to try MPGTX now.

In the Dos command the ' > ' is required for an output file name...

No it is to redirect standard output (console output) to a file.

in this case to concatenate binary files together you would do

copy /b file1.mpg+file2.mpg[+morefiles.mpg] destination.mpg

If these are distinct files the timecodes will likely be way off so the output file won't be great, it would be better to find a program to do this.

You might try Movica. It says you can join two mpegs, although I have not tried.

I've concatenated the files before and then had VideoRedo strighten out the timecode. But he wanted something that was free...

MPGTX makes a corrupt MPEG2 file. I get this error for each input file:

warning: couldn't find any valid system header. I'm continuing anyway

Movica is just a frontend for MPGTX.

I guess I'll have to use the 'copy' method, but I hope VirtualDub-MPEG2 can work with those files. It'd be nice if GBPVR recorded consecutive shows on the same channel as one file.

betbest1 and mvallevand are right. '>' should not be used. Sorry, been configuring a new linux server and it just got stuck in my head from using the cat command a lot.
