  1. #1 Performance on a Macbook Pro 17" 
    Hey, I've done some searching on this topic (both google and here) and I'm really looking to get some answers or at least comparisons.

    I'm currently working on a feature shoot as the data manager, as well as stills photographer (though I don't have a camera..). This requires watching a lot of footage through Redcine.

    We're shooting in 4KHD with a guide track for audio, on build 17. Because we're pretty low budget and this loading station is still in construction in a few different ways, the external drives are usb2.0 and firewire 800 (raid). The macbook is a 2.4ghz high res 17" with 4gb ram and the nvidia 8600m gpu.

    Right now playback tends to stutter pretty seriously, using the ctrl+f1 trick I see that it rarely gets up above 18fps even on 1/4 res medium, which is rather concerning to me, I was really hoping this hardware would be capable of smooth playback at least at 1/4 res.

    Anyone else have similar experiences? are my drives not fast enough? is the video card wrong? should I just have an octo-mac for what I'm trying to do here?

    in the meantime I will probably turn off audio playback since keeping up with audio causes some of the stuttering as it skips frames to keep in sync.

    I think it's a problem of format. 4k HD doesn't work well. In 1/4 res medium you can have real time or close to real time playback (24/25 fps) with 4k 16:9 or 4k 2:1.

    That would make sense to me. REDCODE isn't exactly lightweight :)

    I guess it might be worth waiting for a quad core laptop with firewire 800 that runs os x..
