If you turn MP on make sure that the ACTUAL Cores used plus the Cores for other apps add up to your total cores, allocate memory in even numbers, and leave plenty of memory for other apps (at least 4 GB). Most folks that have problems starve CPU's by trying to throw too much memory at them.
No not like that.
Installed CPUs: 16
CPU's reserved for other applications: 0 -- This is really bad
Ram allocation per background CPU 6GB -- Too much
Actual CPUs that will be used: 8 -- That's only half of what's available.
Adjust your settings to assign at least 2, 4 would be better for other applications and reduce the Ram allocation per background CPU to 4 or 2 gb so so that the total CPUs add up to 16
Installed = 16
Other apps = 4
Ram = 2
Actual CPU = 12
In all likelihood your current settings will either render slower than your system would with MP turned off or the renders will get fouled up. Also, MP rendering will not work well for compressed formats like H.264 or MPEG and do not use Quicktime H.264 for anything because it's no longer supported or being developed by Apple and it was a mess to start with. MOST legacy codecs do not support MP rendering very well at all. It's not Adobe's fault, it is the fault of the codec. MP rendering works best for image sequences.
I usually need to output to h 264 because 90% of my clients need small file size good image quality for web use.
I will try your proposed settings and test render to a png sequence on a video template I use daily, see if it makes a difference and post an update here
The settings you proposed had the same exact rendering times as my settings.
That's because you are rendering to H.264 which does not use Multi Processing. I would use the Adobe Media Encoder for rendering that format and pick one of the presets. It's a better render, you'll get higher quality, and you will be able to work with AE on other parts of your project while you are rendering.
AME does not use MP as far as I understand.
Rendering through AE via MP completes at 1/4 the time it takes AME to finish the exact same render. In some cases even faster.
I use a script called background renderer if I want to keep on working in AE while rendering with several instances of AE renderer at the same time.
Thank you for your suggestions.
I just exported using your settings and an image sequence instead of an h 264 mp4 file, and rendering time increased by 30%.
