Removing audio and halving framerate takes it down to about 13MB, which is much better. I guess that's fair, since BenB17's (outdated) LeafStorm 1 vid is less than half the length but twice the resolution (dunno bout framerate), and is about that filesize. So thanks alot for that piece of advice! =)
It seems Virtualdub can compress audio without having to remove it first like you suggested, but whenever I go to the "Compression" and try to save I get problems. Instead I just went to "Conversion" and turned down the bitrate and precision. Makes the audio sound like shit, but this in tandem with compressing video with DivX 6.1.1 YV12 Decoder (maximum compression settings) got it down to 16MB, or, alternatively, ffdshow got it to 15MB (not changing any settings since that dialogue box is waaay too complicated :( ), which I guess will do for now. I'm not sure what I'll do if I want to have video at higher resolution though (since this one is a bit small), so I guess I could stand for a few more pointers if there are any to give.
Still don't know how to go about uploading it though. E-mail to Rolken? (I get the impression AIM is preferred, but I don't use IM programs anymore for personal reasons)
