[auguste raffael] “Otherwise, is there a better technology? What is Apple’s Quartz Composer technology? Is this a way to sync four movies to play as one?”
It may be possible to save the movie as 4 separate 1920 x 1080 movies (H.264 if you have the processor power, if not try PhotoJPEG with quality “10”), and in QuickTime Player (needs to be the Pro version), move the movies to their required windows and use the “Play All Movies” option (I don’t have QT in front of me so I don’t know if that is the right name).
I am not sure if this works in Full Screen mode. If it doesn’t, another alternative is to compress all 4 movies into 4 High Quality MPEG2 files and use VLC (www.videolan.org) to ‘stream’ each of the movies back to the computer, and have each stream displayed on a separate monitor. Because it bypasses QuickTime, you should have enough bandwidth to do the software decompression.
Actually, try opening the 7680 x 1080 file in VLC. It may have to be converted into H.264, DivX or MPEG2 as I don’t think it can handle QuickTime movies, but it may be able to display it across the screens.
When I get home I will run some tests on a dual monitor system to see what works and I’ll get back to you.
Kind regards,
