SSD disc problem??? Black magic disc speed test
on Nov 13, 2015 at 10:25:05 am

Hello,

Im using mac mini late 2012 2,3gHz, 16giga RAM (1600mhz ddr3) and 500Giga SSD disc (samsung 850 EVO). I can not watch 4k videos on it because I have judder effect no matter what I do. I pasted the video of my BM disc speed. Where is the problem?









thank you!

I have to ask... are the 4K videos stored on the SSD locally or are you watching them from the Internet (e.g., via YouTube) in which case your broadband connection would be the limiting factor?

Also how are you trying to view them? On what screen? the Mac mini doesn't have 4K output???

If you are watching them on an HD display then the 4K is being resized which may slow down playback. (but why would you be watching 4K without a 4K display?)

Clips are stored on my SSD disc. I am trying to open them on FcpX. I have 4k monitor but it is set to 1440p resolution (you are right, Mac mini mini does not have 4k output).

I also tried to downscale video to 1080p (ProRes 422) with "MPEG streamclip" but I get same results.

The video was recorded with DSLR Panasonic GH4 - 3840x2160 25fps

Why didn't you just have FCP X create optimized media for you? Once you have ProRes 422 1080p it doesn't matter that the source was 4K. If other ProRes 422 1080p files play fine than I can't imagine what is wrong with these files other than using MPEG streamclip instead of FCP X or Apple Compressor to convert them. (I've never used MPEG streamclip, I have FCP X optimize my media or I use Compressor)

You might want to repost this in the FCP X forum to get more people who use that program looking at it.

Your Mac mini has the exact same specs as my Mid-2012 MacBook Pro and I edit with FCP X and Motion all the time with this Mac. I don't see why your Mac mini wouldn't be up to the task. Here is what About This Mac says for my MacBook Pro:


Look familiar? It is almost *exactly* the same specs as your Mac mini. In fact your Mac mini has more GPU memory.

A 2.3Ghz Core i7 is fine for FCP X with HD. I'm not sure about 4K. For that I would get the 27" iMac with Retina 5K. ;-)
