Mac Pro For 4k Red Editing
Question: Q: 'Cheapest' 2013 Mac Pro Specs for 4K Video Editing. Hello, If I bought a brand new 2013 Mac Pro, what would the cheapest, minimum specs be in order to edit 4K video without any lag? Would a cheap iMac and a red rocket card be cheaper? I am not doing anything too exciting, just simple video editing and some simple color grading.

I’ve long believed there’s no such thing as “too many pixels.” My desk setup follows that to a tee: I currently use a 27-inch iMac and two external displays, which, when combined, offer me 6656 horizontal pixels of resolution. But this setup, while great, requires a fair bit of head movement—it’s over four feet from the left edge of the left display to the right edge of the right display. Because of this, I’d recently been mulling over 4K displays: They offer many more pixels per inch than your traditional monitor, allowing you to have lots of screen real estate at your disposal without having to fill your desk’s horizontal space with screens. Making such a move can be a pricey proposition, however; even the least-expensive 4K displays are $500 to $600. But then a helpful friend alerted me to a deal on the, a 39-inch Ultra HD TV set with 3840-by-2160 resolution. Amazon has these sets for just $339, and at that price, I thought I’d give it a try. Not for all Macs Before you run off and order a 4K/Ultra HD display of your own, you first need to know if your Mac will support said 4K display.
Checking your Mac’s technical specs on Apple’s website provides the official answer: only the Retina MacBook Pros and Mac Pro are listed as supporting 4K displays. (The MacBook Air and iMac will drive an external display at up to 2560x1600; the Mac mini’s limits aren’t listed, but it’s got an older video card than the iMac, so it’s doubtful it can drive a 4K display.) As I have a 13-inch Retina MacBook Pro, I went ahead and ordered the Seiki TV set. In addition to the TV, I also ordered a mini DisplayPort to HDMI adapter; this adapter is required to get the full 4K resolution from your TV to your Mac. There are many of these adapters out there, and most any one should work fine. I used from Monoprice.com. Initial setup With the TV and adapter in-house, initial setup is relatively simple.
Plug in the TV, connect the HDMI cable to the adapter, then connect the adapter to your Mac. Once everything was powered on, I found I had to do some adjusting to the TV’s settings: it ships with noise reduction on (I disabled it), and with sharpness and brightness values at 50 (I set them both to zero, and increased the contrast).
With these changes, I found the image quite nice—text is sharp and colors (after a few tweaks to color settings) look good. The Seiki's onscreen menus are used to modify the picture settings; I find these values worked well in my setup. For fun, I also tried connecting the display to my 2011-era iMac, and it workedoccasionally. Sometimes when I’d connect, I’d see the full 4K display; other times, I’d see a blue screen on the TV and “no signal.” I wasn’t able to ever make it work reliably, so I’d say if you have an older computer that doesn’t officially support 4K displays, this setup isn’t recommended.
The inexepensive TV I chose will only run at 30Hz at its native 3840x2160 resolution; more expensive sets will run at 60Hz. However, that 30Hz is also the highest level at which the 13” Retina MacBook Pro will drive a 4K display, so I wouldn’t do any better with a more expensive monitor. (The Mac Pro and 15” Retina MacBook Pro can run certain DisplayPort 4K displays at 60Hz, via.) While a 30Hz refresh rate is fine for mostly-static images (like windows and text and photos), it’s not ideal for video; fast-action videos (and video games) will exhibit some ghosting/shadowing. Some people find these issues more distracting than do others; for me, they’re notable enough that I wouldn’t plan on watching a feature-length movie at the 4K resolution setting, though I had no trouble with shorter YouTube clips. Putting it to use So how does one use a massive 39-inch TV as a display? In my case, I’ve put it at the back edge of my desk, about three feet from my eyeballs. It works well at that distance, though if I had a different office layout, I’d consider wall mounting it to move it back a bit further, and allow up/down angle adjustments.
