    Hi all,

    I've just got a GoPro Hero 4 and when I play 1080p 60fps back it stutters, plays back fine when I record in 30fps, I wondered if it's my graphics card? I've got a 1,1 (2x 2.66) with 32gb RAM, USB 3 cards, Radeon 5770, 1tb hdd, and 128gb SSD (system drive).

    I would have thought the 5770 would have been able to run 60fps fine?

    If you're playing it back in finder or just quicktime, just downloaded off the card then mine does that too. It's something to do with the cineform codec I think. Once you process the video through GoPro studio or FCPx it plays fine, so no worries.

    If I had to guess I'd say no hardware acceleration for CineForm.

    Even if I copy it to my SSD and try playing back it still stutters, weird how it's fine at 30fps just not 60, I've tried importing into GoPro Studio, iMovie and also playing back via Quicktime/VLC but still the same :(

    You need to run it through GoPro studio, ie convert it in there. Can't remember the exact process but just follow the steps. it's not a hard drive speed issue.

    Weird, step 1 in native form (and from finder) play choppy but when I convert into edit mode (step 2) it plays fine, any idea why this is?

    I don't like using GoPro Studio as it's really limited, I don't like how you can't combine all the clips into one like you can in iMovie.
