Right now I am preparing a show for a museum. A video with a resolution of 3414x720 will be played from computer (pc or mac) through a Matrox TripleHead2Go Digital Edition Card, into three video projectors which will show the image as whole.
My specific part on the job is to get the computers to play the video. I would like to know what is the best codec that I can use (for PC or MAC)? I need the lightest, easiest codec to play on a computer, that will use the least resources. Right now I am trying ProRess 422 for Mac, and WMV for PC, is that the best I can do?
