VirtualDubMod is a program that allows you to choose the start/end of a larger file and make short clips.
I have only done this with AVI files, so I dont know how it handles other formats. Theebs may have some better options.

Yep, vdub for me too. Follow these steps:
File/Open video file.
File/Video/Full processing mode.
File/Video/Smart rendering.
File/File Information and find the codec name and the data rate.
File/Video/Compression and select the matching video codec (normally DivX or XviD).
Set up the codec to one pass mode, at the highest quality level("Insane Quality" for DivX) and fill in the data rate in the bit rate field. Make sure the codec is not set to do any clipping or resizing
or any other special things, and is set for Progressive rather than Interlaced mode (unless the AVI file is actually interlaced, which is
very rare).
Close the codec settings.
Resize the left hand (source) video window to a good size for you to see what you are doing. Right mouse button on it and set the aspect ratio (usually 4:3 or 16:9) so that the picture looks right.
Use the slider bar and controls at bottom of VirtualDub to move to the frame you want to cut at. The buttons all have tool tips to tell you
what they do. The ones that move by keyframe are very useful, as cutting is best done at a keyframe since VirtualDub can then just copy
exactly the frames from the source file, without any recalculation (and consequential slight loss of quality). The keyboard arrow keys move one frame left or right. Holding down the shift key while
dragging the slider moves by keyframe, which is very fast and the best way to move around a file. Moving backwards (except by keyframe) is
very slow as VirtualDub has to go to the front of the file and move forwards by keyframe to the keyframe just before the frame you want,
and then calculate each frame forwards from there to the exact frame. You can see it doing this on the bottom line of the window. Only
after a number of seconds will it be able to display the frame you want. Shifted arrow keys move by 50 frames in either direction, which is also very useful. Keyframes are marked with a [K] beside the frame number and frame time at the bottom.
Once at the frame you want to cut at (preferably a keyframe), click on the "Mark out" button (rightmost).
F7 and select the name of the output file to save the selected section of the file from the "Mark in" frame to one frame before the "Mark out" frame. You can optionally set the flag "Don't run this job now;..." and just queue up the job to be run later from the F4 batch window. If you are cutting other than at keyframes, this is a good idea as it is much slower doing that. Once the save is finished, click on the "Mark in" button to set the mark in point for the next split at the next frame after the end of the split you have just saved. Move the frame cursor to the next mark out point and repeat the process.
