Well forcing users to install a plugin to view your quicktime movie is a bit overkill heh. I mean, i am trying to make it Quicktime compatible so that they can view it and because its the standard. I think i may have found a solution though, a bit more testing is needed before i can confirm.
my h.264 settings using ffmepg are here: http://www.vimeo.com/1242373 but using the QT on my machine resulted in a file that was 10x larger, so I gave up on the mov. e.g. 5 minutes was 770meg, but it worked, but they were huge. In QT, just click set codec, and Best, H.264, 4000kbps.
