- The actual recording, done using TechSmith Camtasia's built in screen recorder (1920*1080 px, stereo, 8 minutes), was 200MB. (TechSmith also sells SnagIt, which can do the same thing, and also some screenshot copying that can't be achieved with the Snipping tool.)
- When exporting to MP4, the resulting file was 84MB in size. Its "compression ratio" is set to 75% (the higher the better quality, so it's really not the compression ratio but you get what I mean
- The 84MB file is sharp enough; it looks similar to the YouTube movie.
