Codec Chaos
Foo.
My new DVD burner came with a library of video and DVD editing software from Ulead. This prompted me to try something I've wanted to do for a while. I have all these anime files on my computer, and I'd like to put up some little video clips to show people just what it is that I'm talking about - without them having to download entire episodes at 200 meg a pop. The program found my collection of codecs just fine, which was a relief. Most of the files are in non-standard formats such as DivX (unrelated to the failed attempt at selling pay-per-view DVDs) and Xvid, which are variants of MPEG-4. The program read the files just fine, and allowed me to select from these and other codecs for my output. However, the file produced for a 90-second clip came out to 25 meg. No matter what I set the bit rate to, it comes out at 25 meg. Except sometimes when it's even bigger. The one success I've had was with RealMedia format, which produced a 1.5 meg file for the same clip. The picture and sound quality was... About what you'd expect. Awful. I'm sure there's a trick to making this work, but I'm not going to find it tonight.

Have you tried changing the Frame Size (resolution) of the video? Also make sure the audio is being compressed, it can take up a huge amount of space if uncompressed.

Yep. Though dropping the frame size turned out not to do much. I did reduce it to 15 frames per second, which (surprise!) cut the file size by nearly 50%.
More experimenting is in order, I think.
