Hi – It’s two years later, but your dialog was so thorough and clear, I thought I’d try here. My situation is this: Professionally editing for years and years, work out of home now. I’m cutting in Premiere for the first time in Arri C 4444, and it lags, and stutters and staggers and lag. Interviews are two-camera, so that’s two video levels, plus one for Broll. If I render a section, it all runs smoothly.

Sequence is matched to the 2K Arri footage: 2048×1152, 23.976 fps. Screening at 1/2 quality. (lowering it 4o 1/4 gets it to run… but it’s nearly unwatchable, and hurts the creative process….).

The set up: your standard imac: 3.6 ghz, 24 mbRAM, Core i7. Media’s on a 4TB OWC Thunderbolt Raid 0 pair of HDDs at 7200 rpm. Renders and Previews go to a .5TB SSD. The program’s on the internal 2TB drive.

I’m beginning to think that I should just edit low-rez ‘proxies’ like the old days…

Is the CPU simply not fast enough? How fast does it have to be for the system to play multi cam interviews in real time? Am I just expecting too much? thanks!
