ClearType makes bloated Screencasts
I've been making movies for ShowMeDo about Nose and PyWinAuto. As a matter of course, I turn off Windows ClearType rendering. It looks pretty, but I don't think it's worth the bits.
I recorded the same movie with and without ClearType, capturing to Microsoft Video 1 at 100% (lossless) quality:
- ClearType ON : 31,157 KB
- ClearType OFF: 11,263 KB
The movie had audio, and things get even more interesting when looking at it with GSpot:
- Cleartype ON Bitrate: 11743 kb/s
- Cleartype OFF Bitrate: 3219 kb/s
So: Cleartype makes the video 264% bigger. Is it really worth it?
