Four 4K streams on MacBook Pro late-2013

Although Apple are promoting the 2013 Mac Pro and Final Cut Pro X 10.1 as the ultimate 4K tools you can get good results on the new MacBook Pro late-2013 2.6 Ghz Quad Core i7 16GB 1600 MHz RAM 1 TB SSD with Discrete GeForce GT 750M 2GB GPU option running OS X 10.9.0 I uploaded an 1080p version of this video but YouTube encoded it as 720p. Slightly better encoding will be available over at Vimeo soon. Pity neither service can do much about my camera work!,
