1. What will happen if you attempt to playback 4K video on a iMac since it does not have a 4K display? Will it just play very large/zoomed in? 2. Anyone know if the Quicktime player on a Mac will play back 4K video? 3. I have a new 2013 iMac (highest end) and use Premiere CS6. Anyone know if this setup will be able to edit 4K video from a Sony FDR-AX100 camera? It currently has the minimum amount of RAM though I'm going to max it out. Thanks!
