so I am editing some 4k footage, already got it down to 1/8 res, preview file format (in sequence settings) to P2 1080i and made 1080p proxies (which also took ages to encode in Media encoder)..
I've also pre-render the in and out points. I get a fluent playback, but with adding effects (color correction) I have to wait couple of seconds to even see the result of my changes. And immediately as I move a slider, the green bar above the timeline turns to red again. WTF ?
I am editing on a Macbook Pro Retina and usually things are pretty fast..
