user3380: What is a simple way of extracting a video clip from, say, an .avi file? An example: I only want between 1:05 and 1:35 of this video, and I want to save the clip as its own file. I have been using Premiere Pro but it has not been particularly efficient.
Thanks!

user3029: VirtualDub is probably the best tool for trimming/splitting AVI files (without recompression). For other formats, you should look for other tools, eg.:

Avidemux 
AVS Remaker 
etc.


user2178: You can use FFmpeg to accomplish this. FFmpeg is a command line tool that is used to convert and cut audio and video.
 From this answer I got the sample code which I have rewritten for your purpose.

ffmpeg -ss 00:01:05.0 -t 00:00:30.0 -i input.avi -acodec copy -vcodec copy -async 1 output.avi
