How to join or split AVI videos without re-encoding?

[cos.]

Googling for how to do this on OS X (I have Snow Leopard) turned up some suggestions to try AVITools, which I downloaded. However when I take an AVI file straight off my camera card and open it in AVITools it tells me "could not identify video track".

I'm not wedded to AVITools if there's another option out there. Is it better for me to spend some time trying to troubleshoot this specific problem, or should I look for something else? I'm not sure.

Do any of you have an easy way to join or split AVI videos on OS X?

(I understand that to do this the videos inside the AVI files would need to be the same format, but I want this to work with videos that are all from the same camera so that's not a problem)

Huh, what suggests to you that it's possible to do so using that piece of software? I didn't see anything on its web page that indicates it can do it. Just in case, I downloaded it and ran it... and I still don't see any such feature. What am I not noticing?

As far as I can tell that program does not do this.

However, I found a solution, at least for joining videos: avidemux

Thanks to a reddit commenter on my post there.

install MacPorts https://www.macports.org/install.php

port install mplayer

installs mencoder

cat file1.avi file2.avi file3.avi > video_draft.avi

after appending the data together using cat above, you need to re-index the draft movie like this:

mencoder video_draft.avi -o video_final.avi -forceidx -ovc copy -oac copy

Now you're video_final.avi file will be right to go.

Wondershare Video Editor for Win & Mac
• Trim, cut, split, merge, rotate and mix videos/audios/photos

Note the word "merge", taken from the webpage

Add your movies then go to the Share menu and choose Creating Video...

I have now, and it works fine for me.

I have another solution, QuickTime 7, which still works in Mountain Lion.
Steps:
1. Open both movies in QuickTime 7.
2. In the 1st movie, go with the marker to the end of the movie.
3. Go to the 2nd movie and go to the the "Select All" command in the Edit menu (or use the shortcut of your preference)
4. Select the "Copy" command in the Edit menu (or use the shortcut of your preference)
5. Go to the 1st movie and select the "Paste" command in the Edit menu (or use the shortcut of your preference).
6. Select the "Save As" command in the File menu. Navigate wherever you want the new file and hit Save

One caveat: the movie will be saved as .mov
