Simplest way to convert and join avi's with different audio streams??

[Lolipop Jones]

File number one is 111 Kbps VBR MP3 2ch
File number two is 85 Kbps MPEG-1/2 L3 2ch

Tried to join them in virtualdub, no joy for the obvious reason

Then I tried to reencode them in AutoGK, file #2 is "unsupported audio type"

The reason I am posting in the noob section is that I'm afraid I'm going to be told I have to somehow detach the audio from the video files, do some fiddling with the audio and then reattach them, and I am indeed among the noob-iest when it comes to that whole world.

As you have already feared, you will need to get the audio/video streams to match before you can join them. You could use an audio tool such as GoldWave or Audacity to extract the audio stream and convert it to CBR mp3, then a tool such as VirtualDub/VirtualDubMOD to combine the video with the new audio streams. You should also be able to just use VirtualDub/VirtualDubMOD to perform the whole process. There should be a guide or two floating around here with the exact steps.

You may also have issues if your video specs are different (ie: resolution and/or FPS).

I don't use AutoGK, but I believe it uses AVS scripts to feed the AVI files inot VirtualDub -- if that's right, can you load file1 and then modify the AVS before going to the next stage?

If you get an AVS file like :

AVISource("file1.avi")
blah()
Blahblah()

try editing the first line (with a text editor, like Notepad)
to join the second file:

AVISource("file1.avi") ++AVISource("file2.avi")
blah()
Blahblah()

Avisynth converts the compressed audio (and video) to an uncompressed format, so it should be able to join hte audio.

However, if the video frames are different size or rate, you would need to filter them before joining.
