joining mpg's and de-multiplexing it again

[sala]

I have 2 avi files which i framserved with vdub (extracted the audio to 48khz) into tmpgenc (ntsc-film / 48khz - 224kbit - 2500cbr)

Then i joined these 2 newly made mpg's with mpegtools.
Audio completely out of sync.

Then i tried DV-Tool to join those mpg's, result, audio in sync.
MPEG1+MPEG2 : NEWMPEG 4,01GB

Now i want to demux the new MPG so i can use ifoedit to burn them on a dvd.

Using tmpgenc's mpegtool doesn't work. It stops demultiplexing when it reaches the end of the first mpeg. also the sound stops and the end of part1.

I tried PVAstrumento which gave me like 26920 errors and a result of 30mb of video, instead of the 4gb

Anyone have an idea of what might be wrong ?

If your have multiple AVI's, you would normally use VirtualDub to join them before encoding. If the audio in your AVI's is AC3, then you need to use AC3FIX.EXE to repair the bad frames, or audio sync problems will result. You can then take your fixed output, and encode as usual.

It sounds like your encoding each avi to MPEG seperately and then trying to join them? Join them first. Repair if necessary, and then encode.

DJRumpy is right, the best way to join these is at the AVI format and then encode.

If you still think your problem is at the muxing step, give XMuxer a shot. They have a free trial http://www.elecard.com/download/

Problem is that sources of both avis are differnt and vdub hates that

AVISynth likely can do what you want. If you don't have AVISynth 2.0 or newer, go get it and install it on your computer. http://www.avisynth.org is the official site.

Now fire up Notepad and type in the following:

return(avisource("clip1.avi)+avisource("clip2.avi"))

Click File->Save As
Change the file type to "All Files", then type in the filename you want (ending with .avs extension, this is a must for AVISynth)
Now encode the .avs file with your favorite Encoder (TMPGEnc!). AVISynth will join the two AVIs and feed it to the encoder automatically. This is called "Frameserving".

I actually was able to use AVISynth to edit my daughter's Christmas program for putting on VCD. It worked pretty well too.

AVISynth will work, but you should first make sure that both clips are the same framefrate, and resolution. Although the script posted above would work, you could get some interesting results .

What are the differences between the two clips?
