OnTheAir Video Express is the ultimate QuickTime playout application on the Mac for professional looking playlist playout when using third party video cards or the Mac's own Mini DisplayPort or HDMI ports. OnTheAir Video Express can output in both SD (standard definition) and HD (high definition) and will even resize your SD clips to HD when outputting HDMI. It can output to your screen ANY file that QuickTime can read.
