Steve, what Ramil says is not entirely correct. On my system (see below) I am able to play Red files natively with real time playback. I do not have a Red Rocket card. By setting the Program Monitor to 1/2 resolution (which for Red is still 2000k) I have no problems. And I can even do a one light in the Source mode of the clip. Yes, memory, CUDA graphics card, and high speed disk arrays add to the Mercury Playback Engines abilities. But a Red Rocket card doesn’t necessarily need to be purchased.
