Does anyone have software that will cut out the audio to reduce the file size? I don't have anything that will do it but I can't pay anything. It's just a short clip.
You can also use VirtualDub (as mentioned above) with a suitable encoder, like Pegasus MJPEG compressor installed.
By default virtualdub outputs in raw avi. It's easier to edit and manipulate raw video.
Another trick you can use is reducing the output frames. For example, if your original video is 30fps you could tell virtualdub to output 20fps or even 15fps before compressing.
