| I can comment on some of this. A hot GPU will help most in Pr if you stack GPU accelerated effects, and for the encoding / export of H.264. Ae hasn’t gotten around to using the GPU on too many effects yet. You didn’t say what codec your source footage was. Long-GOP codecs will stress your CPUs more as the footage is more compressed. If you layer several highly compressed Long-GOP clips, you can expect playback performance to suffer. I’ve not noticed much difference in OSX versions as far as Premiere performance, up to El Capitan, 10.11.6. Newer OSes seem to boot faster than the previous ones. SSDs boot faster than spinning disks, too. Your MacPro5.1 should hold 128 GB of RAM. I recently upgraded to that model from a 3,1 with a max of 32GB RAM, and I was having to purge the RAM frequently, as the RAM would fill up and start dropping frames like crazy. Now, with 128 GB of RAM on my 5,1, with Ae running simultaneously, I’ve so far not maxed out all the RAM, and have only gone as far as like 24GB left (which is what my settings reserve for other apps). I have the hottest GPU for Mac, the Nvidia Titan, and the combo of the RAM and the GPU has made a substantial difference in terms of render times and real-time playback (vs. the old 3,1 lesser equipped with RAM and Nvidia K5000 GPU) of the sources I receive from clients, which is a variety of AVCHD, AVC-Intra, Sony MXF, Sony XD-Cam, ProRes, etc. I often edit with 4K and UHD sources, and most often finish at 1080 HD. It might not be wrong to infer that UHD HDR will use more RAM. A lot of producers / shooters have been seduced by 4K, and buy cameras with a crappy Long-GOP codec that slows the native post process. That said, I can generally play back 4K without dropping frames that isn’t in a RAW format. I rarely have more than three or four video streams playing simultaneously in Pr. > On Feb 28, 2018, at 12:55 PM, email blanca <AE-List@media-motion.tv> wrote: > > Greetings… > > Re: [AE] Premiere with UHD HDR10 material. > > Can anyone comment on editing 3840 x 2160 HDR 10 material in Premiere? > > I am trying to build some test patterns and I am finding once I reach a certain number of layers, I lose the ability of the GPU to render the program monitor. > > I’m running a 5,1 MacPro 64GB ram, 3.43 Ghz 12 cores, nVidia GTS 980 Ti 6GB, 10.10.5 and CC Premiere Pro 2017. > > I wondered if I might get different results upgrading to 10.11.x or 10.12.x, or switching to a better GPU? > > I can send sequences to Media Encoder and they are rendering fine to HEVC Main 10 bt 2020 HDR. > > I’m gonna try AE to see if it might work out better. > > Thanks in advance. > > RJ > mactunes > > +---End of message---+ > To unsubscribe send any message to <ae-list-off@media-motion.tv> |
