That's never been my experience. I compressed some files to compare. Windows Movie Maker didn't give me many options so I went with the 768kbps, 320 X 240 30fps preset. Windows Media Player says it's 705kbps when it's playing back which pretty much meshes with the math (it's 1.3MB).

It's 320 X 240, 30 fps, 759kps (1.37MB) <URL: http://michaelverdi.com/codec/3ivx.mov > The other is encoded with H.264.

We can certainly do more comparisons at other (lower?) bit rates. I've also posted the source video. It's DV shot on a one-chip Digital 8 camera. It's in an avi wrapper so it will work on both a mac and a pc. If someone with a PC and more wmv encoding option would like to compress some samples, I'll make 3ivx and H.264 versions using the same frame size, fps, and bit rate. The source file is at: <URL: http://michaelverdi.com/codec/source.avi > All three of these files are perfectly acceptable for videoblogs. Many people (casual viewers - not people who scrutinize video all day) would have trouble telling the difference between them. I just don't see how you can say that a 3ivx quicktime file at the same size as a wmv file is far far worse. -- Verdi <URL: http://michaelverdi.com/ > <URL: http://freevlog.org/ > <URL: http://node101.org/ > ------------------------ Yahoo!
