It sounded like something that was really easy to do when Hans Mestrum explained it on his blog (in Dutch), just upload a video in high resolution to YouTube, add &fmt=22 to the URL and you can watch the video in true HD quality.
Hans demonstrates it with a video that he had shot at the HAN and that he had uploaded to YouTube.
I wanted to try it with a screencast that I created using Camtasia Studio 6 but my first attempt failed. That video isn’t recognized by YouTube as a high resolution version.
Of course I didn’t give up there, but got more determined to find out why it didn’t work.
