I’m one of those people, I have an 27′ imac i7 with a 3.4 ghz quad core with 16GBs of ram and a 1GB AMD Radeon HD 6970M video card. The screen resolution is 2k (2560 x1440).
I know i won’t be able to watch it in true 4k. I just want to know if theres any other way (besides transcoding footage) to make the native files playback smoother when editing and not have to change the resolution quality to 1/4. So really this isn’t even a question about actually resolution its more or less getting the R3D files to run optimally in premier.
