These are instructions on how to join/combine avi video files using QuickTime for Mac OS X. If QuickTime can't read your avi file then you may need to install the Perian component from here.

Step One
Double click one of the video files that you would like to join to open it in QuickTime.

Step Two
Move the scrubber to the position in the clip where the other video will be inserted.

Step Three
Drag another clip into the QuickTime window to insert it before the scrubber.

Step Four
Select Save As from the File menu

Step Five
Enter a name for your the combined video file then click the Save button.

Step Six
QuickTime will now save the joined video.

Step Seven
After a couple minutes the avi video files will be joined and ready for playback.

Wow. I can not believe this works on something like an AVI file. Amazing! Thank you SO much for sharing that. Why do all these apps even exist? Jesus.

Or you can use this script I wrote: #!/bin/sh set -x if [ -z "$1" ]; then echo =e "\nUsage: `basename $0` Base_Movie_Name_To_Be_Joined" exit 1 fi cat $1* > _$1_.avi mencoder -forceidx -oac copy -ovc copy _$1_.avi -o $1.avi rm _$1_.avi So you run it like: ./join_avi.sh Video which will combine Video* into 1 avi file and re-encodes it preserving it in divx format.

Uh, you should also note that the user needs to have Perian installed in order to open a .avi file properly in QuickTime.

Screw this method. I don't want it to be a .mov file. I have used avi joiner in the passed, but it's screwy, so I just convert and join them together in visualhub, or join them together in SimpleMovieX.

This just changes the container to mov it does NOT re-encode the file. Who cares what the extension is?
