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.

1 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.

2 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.
