I usually use Snagit for recording screen and share it with people. I also asked for WebM support which has a much lower size. Anyway... Please add ability to reduce MP4 size on saving (pleas take Camtasia save dialog and put it to SnagIt) so resulting videos will be of lower size. Please also use compression from Handbrake, because it produces videos like 200kb out of 5mb saved by SnagIt.
