Thank you Jim=E2=80=A6

I=E2=80=99m digesting your comments but wanted to follow up.

This current effort is creating custom UHD HDR10 test patterns.  I =
started with some .mp4 files in the HEVC Main 10 BT2020 HDR codec. Files =
that one would use for calibrating a projector or a display.

I have two sets of calibration files I have been playing with=E2=80=A6

1) the calibration file on can find on all Sony UHD HDR BDs.
2) Ryan=E2=80=99s HDR10 test patterns.

Using these test pattern files, once I get beyond a 5-8 layers, I start =
having issues with random noise in the project monitor and sometimes on =
the desktop. Sometimes the program monitor will not even outoput an =
image. I often have to restart to clear the GPU and system ram, and I =
can proceed once again until the problem occurs again.

I then tried replacing the original test pattern video files with image =
layers adjust to the various HDR10 luminance values of the test pattern. =
With this approach, I can get to maybe 20 nested image layers before I =
start having the same issue of the program monitor not rendering an =
image. I can get many more layers with an 8bit source layer, so I=E2=80=99=
m assuming it=E2=80=99s the extra needs of the 10bit layer that is =
jamming things up.

I also noticed when working with the 10bit luminance range, some effects =
like LEVELS will cause the layer to remap to an 8bit luminance range. =
Turning the effect off restores the 10bit mapping. This is what I was =
gonna try in AE to see if AE is more 10bit friendly.

I=E2=80=99m also curious if FCP X or Resolve tend to me more friendly =
with HDR & 10bit?

I will look into pickng up 8x 16GB chips. I did try leaving more memory =
for the system as well as switching between performance and memory =
settings.

I will be working on a small, free project shot with the Sony AX53 and =
Panasonic 981K camcorders in 4K. Not sure if I will try editing in the =
native codec at 3840 x 2160, or I will transcode to HD for editing and =
finishing and call it a day. It=E2=80=99s gonna end up the web anyway.

Last thing I=E2=80=99d love to ask=E2=80=A6 if there is a most stable =
setup for Premiere Pro?  For instance, which version of OS X and which =
version of Premiere.  While I want to keep a SDD of 10.10.5 available, I =
can rebuild an alternate SSD with a better setup and then maybe see =
about letting that become my main setup.  One other benefit of moving up =
to atleast El Capitan, I could run Resolve under OS X instead of =
switching to Win 10.

Thanks again for your feedback.
