I made my first test movie, exported it as a reasonable quality h.264 .mov file and put it up on .Mac for my pals to see. Unfortunately, I have a few Windows using mates who don't want to install QT7 (they're so paranoid that their systems are currently stable than they don't like introducing new apps) so they can hear the audio but apparently can't see the video. So... what's the best option to create something that they can see without installing anything - at the moment, they're back to slagging off the Mac for being incompatible with the real world - at a decent quality so my transitions etc still look good? If they're hearing the QT audio and not the video, would it be worthwhile, me encoding it at Sorenson or one of the other codecs in QT6 and seeing what happens? I've had a read through the ffmpegx and the divx (tho it says it's not Tiger/QT7 happy) pages but am still not much the wiser. And would I be better re-encoding from iMovie rather than just converting my high quality h.264?
