Hi I'm new to this forum. I've been trying to find users on the net with experience with editing 4k video footage, or editing magic lantern hacked raw 5d iii video on the-new imac. I know a Mac Pro is going to be the obvious choice here, but still, I'd be very curious to hear some real world results from users who have done so. I can find very little info in this area. I work primarily as a photographer and sound designer and for these my 2009 i7 imac is still going good for my needs. Recently however, I've begun to blend my sound and visuals with experiential time lapse work and doing the odd bit of video. Working with the latter is why I need to upgrade now, but as I'm not sure how much video work I'll end up doing, I don't want to go with a Mac Pro if I can get away going with the 5k imac (maxed out) I would like to use the Magic Lantern hack on my 5d iii for video work or maybe shoot 4k next year for whatever video work I'll be doing. This May or may not end up been quite little- I would be happy to work with proxies in FCPX and I'll be adding a RAID 5 setup soon. My videos will be all under 10 minutes max. I do however seem to work with three or four layers at a time. Would I better off looking at a 6 core Mac Pro (the most I could afford). Any help is much appreciated.
