    Which Mac to buy?

    Hello All!

    I am looking to purchase a Mac which will give me smooth full screen at full resolution editing of 4K video in Media Composer and have tested out simply adding 4K and HD (1920 x 1080) footage into the timeline and viewed them at fullscreen but on both the machines below, I get choppy playback. For reference, the videos when played in Quicktime, play perfectly at fullscreen. Would anyone possibly have any recommendations for which Mac I should be looking at, to get the smooth fullscreen or if something else might be the problem?
    Thanks for any help you can provide!!! Stefan
    Notes:
    - I tested the 4K video via AMA (choppy playback) and imported the 4K clip at the 1:1 default setting (extremely choppy). Testing on both machines below yielded the same results for me.

    Re: Which Mac to buy?

    I think Job's point is valid.  To try and play uncompressed 4K from a single USB 3 drive seems like a pipe dream.

    And keep in mind even if QuickTime plays it back, that's all QuickTime has to do...Avid has to be able to do many, many more things than just play a clip in a simple interface.

    Perhaps some sort of RAID would provide you the throughput you need with the CPU you have?

    Re: Which Mac to buy?

    So for testing purposes, if I save the 4K clip on the local disk, and try playing it in MC on either of the two Mac machines mentioned above, should it play smoothly? Or does having a RAID drive allow for quicker access than the local disk?

     

    Or would I just need to get the maxed out $10,000 Mac Pro to acheive what I'm looking for?

    Re: Which Mac to buy?

    Jobs comment was actually spot on. Depends on what is on the timeline and  the effects etc.... But you can certainly test the software using the trial version and see how that goes.  I can probably get some concrete data for you but may take a da or so as our hardware team is at NAB. I'll check with them on the 2 Mac versions and see what they say. I do know 4k on USB3 isn't really going to work.

    Re: Which Mac to buy?

    Let me be more clear. Can someone please tell me what Mac machine and external storage I need to buy to get smooth full screen editing of 4K footage using the Media Composer 8 which I own? My budget is $15,000.

    Thank you.

    So for testing purposes......

    1. Download these two apps so you will know the speed of the drives that you have                                                              a. BMD      https://itunes.apple.com/us/app/blackmagic-disk-speed-test/id425264550?mt=12                                               b. AJA       https://www.aja.com/en/products/aja-system-test

    2.  Know the speed it takes to use certain footage. And no 4K is not on this chart, but if your "drive speed" is below these numbers there is a good chance 4K will struggle to play.   (attached)

    3. Getting a maxed out $10,000 nMP would be the most expensive "test" available! Read here about nMP's and the 2011 GPU's and such    http://forums.macrumors.com/forumdisplay.php?f=1  (use the search engine)

    4. When "testing", use multicam playback as a template using a. R3D  b. Alexa  and c. GH4    In the end you will know where your system stands or crawls. Smile

     

    PS: It should/will not take $15,000 to play 4K on a Mac. Just a little thought, research and the right configuration.

    Re: Which Mac to buy?

    What is the source of the 4K and 1080p footage, in other words, from which camera does it come from and what format and codec does it come in?

     

    I ask, as I was able to play back 4K RED footage via transcoding to the DNxHR HQX in Media Composer 8.3.

    Playing one clip back seemed to take 93 MB/s in MC, which can be done with an external USB 3.0 drive.

     

    Also what MC version do you use, what project settings did you use and how did you transcode the footage to Uncompressed (which is probably overkill depending on the source)?

    how old is this forum software?

    Thank you.

    You were very clear in your original post. There are a couple of ways to approach your work flow. 

    The 5,1 cMP (classic Macpro) and the 2013 (there is no 2015 nMP,yet) 6,1 nMP (new Macpro)

    Attached is a chart comparing the speed of PCIe and TB2. Hopefully someone will chime in with an nMP stating practice not theory.

    Re: Which Mac to buy?

    Try using one of the DNxHR codec settings rather than 1:1 when bringing in your 4K material.  As you haven't yet stated what the source is, I'm going to guess that it's fairly compressed which would explain why your USB 3 drive speed is not the limiting factor.  If that's the case, you're unlikely to lose any resolution using a DNxHR codec.  You can try the different flavors of DNxHR to see which one(s) work best, then depending on your results, you'll know what kind of throughput you'll need from external drives.  A single USB 3 drive is going to struggle above 130-180 MB/s.  Note that the internal flash memory on the new Macs are crazy fast but of limited capacity, so external storage is probably a necessity for longer projects.  If you want to do 4K, conisder a Thunderbolt RAID.  If you want to edit in 4K consider a Mac Pro or a iMac Retina, not a laptop.

    Must think of something clever to go here...

    Re: Which Mac to buy?

    Thank you for all the info everyone. I purchased a G-tech 6TB Raid with thunderbolt connection to try out, and I definitely noticed great improvement both with AMA and DNxHR HQX transcoded 4K playback vs storing on the USB 3.0, but is there a way to save to and run bin media from my internal drive just to test the video playback performance that way? The "filter out" button is unchecked, but my internal drive is grayed out and I can't select it as a drive to transcode or import to. I'm i missing something here?

    Thanks
