DAVINCI RESOLVE FOR MAC - CERTIFIED CONFIGURATION GUIDE
With the increasing use of digital cameras, many
colorists want to grade UHD, 4K-DCI or higher
resolutions in real time. While some cameras provide
UHD or 4K or higher capture resolutions they usually
store the images as compressed data as this takes
less storage space and bandwidth.
However for grading, the compressed data needs to
be decompressed to the full RGB per pixel bit depth
which will use four or more times the processing
power of a HD image for the same real time grading
performance. The GPU RAM therefore becomes a
very important factor when dealing with UHD and
4K-DCI timelines.
A 2012 Mac Pro with a current model GPU and 3GB
or more of GPU RAM can play UHD and 4KDCI
resolution images using a HD resolution timeline
and displayed on a HD monitor. After you have
completed your grade simply change the timeline
resolution for a UHD or 4K-DCI render.
You can also grade and display UHD/4K-DCI images
if you connect a PCIe expander to your Mac Pro,
with extra image processing GPUs, and use either
the DeckLink 4K Extreme or UltraStudio 4K video
I/O card to connect to your 4K-DCI grading monitor.
However with this current MacPro real time playback
is not always achieveable.
There are many potential speed limits within this 4K
pipeline so depending on the clip codec, CPU speed
and number of cores, system RAM, the number of
GPUs, their core count and GPU RAM, motherboard
slot speed, disk speed, etc. each of these can affect
the full 4K playback grade and display in real time.
For facilities that require full UHD or 4K-DCI
playback, grading and monitoring in real time we
currently recommend consideration of the fastest
Linux or Windows configurations we list in the
respective configuration guides or a short wait for
the new Mac Pro.
