Do any of you capture video from the screen for use on a web-site? If so, in what format do you save your output? I've made some intructional/revision videos for students - how to do various things in Office and Open Office, basically - using CamStudio. As these are on a web-site, I'm looking for the best sharpness:size ratio. I've tried pretty much all of the options in Any Video Converter and ended up with low frame rate MP4 as the only way of getting sensibly-sized videos that are still sharp enough to read. Unfortunately, this seems to cause problems for a lot of students as they haven't got the relevant codec installed at home, and they don't always play even if QuickTime is installed. Now I'm also thinking of giving our site an HTML5 overhaul, and MP4 isn't universally supported by browsers that support the <video> tag. Has anyone got any good suggests for format and/or conversion software - including bit-rates, frame-rates and the like?
