Frustrated with Dynamic Link. Does it really just suck?

Hi Vishesh, some good pieces of info can be had here –

AND

AND

The following info is taken from Adobe’s Todd Kopriva in the following thread – https://forums.adobe.com/thread/734343?start=40&tstart=0
When you assign RAM to background processes for Render Multiple Frames Simultaneously multiprocessing, you choose from a small number of options in the RAM Allocation Per Background CPU menu. But you’re not limited to the values in this menu. They are just presets. You can change these presets in the text preferences file.

For example, you could change the value for “MP – Allocation Per Background Process Preset V” to “4.000000” instead of “3.000000” to create a preset value of 4GB. Then, you could assign 4GB to each background process.

Here are the relevant lines of the text preferences file:

[“MP – CS5 – 4”]
“MP – Allocation Per Background Process” = “1.500000”
“MP – Allocation Per Background Process Preset I” = “0.750000”
“MP – Allocation Per Background Process Preset II” = “1.000000”
“MP – Allocation Per Background Process Preset III” = “1.500000”
“MP – Allocation Per Background Process Preset IV” = “2.000000”
“MP – Allocation Per Background Process Preset V” = “3.000000”

For information about the preferences file, including its location, see this page:
https://help.adobe.com/en_US/aftereffects/cs/using/WS37cb61f8f3397d86-1 64c9f19127035dd253-8000.html

Keep in mind that Adobe doesn’t officially support making changes to the text preferences file, so be sure to be careful about making changes, be sure to make a backup before you make changes, et cetera.

Todd’s post provides info on how to change the Prefs File to increase the RAM Allocation for background processes. Take note that the list maxes out at five items. Thus, when editing the Prefs File, at the specified location, do not add to the list but rather change the values of the existing list to reflect your desired values.

These are good stuff to know but you should take note that the recommended settings for optimal performance may change in the future.

Roland and Walter, Thanks for sharing the information about rendering process. I learned a lot today.
Thanks a lot!

I’d like to touch on the following which I posted in a related thread just a while ago – to help make this thread more complete.

The following AE Team’s blog post is a good read on the topic. – https://blogs.adobe.com/aftereffects/2010/03/performance-tip-dont-oversched.html

The best take-away message IMO is the following – “After Effects is a multithreaded application that can also use other forms of multiprocessing beyond just Render Multiple Frames Simultaneously multiprocessing”. Seeing that you are having issues with RMFS, deselect MP (aka Render Multiple Frames Simultaneously) in AE’s prefs dialog. Set aside some RAM for other applications. Such a setting will allow AE to manage its multi-threaded/multiple processing architecture on-the-fly.

If you have sufficient RAM, and the plugins you use support MP, then you should have similar, not necessarily better or worse, experience to having MP selected in the prefs dialog.

At issue is the conventional wisdom among AE users that multi-processing or working with multiple processors is only available via the Render Multiple Frames Simultaneously (RMFS) setting. This is of course incorrect.

Hopefully, folks that face issues with RMFS failing to take off will now find it reasonable and even correct, to simply switch off RMFS and to proceed with their work productively based on their project requirements and hardware.

[Roland R. Kahlenberg] “Hopefully, folks that face issues with RMFS failing to take off will now find it reasonable and even correct, to simply switch off RMFS and to proceed with their work productively based on their project requirements and hardware.”

Yes, well-stated!

A lot of people focus on the wrong render metrics: CPU load or memory usage. The only metric that matters is render time.

A shorter render time with excess free system resources is far, far better than a longer render time on the same system due to overscheduled processors (fully loaded CPU) or RAM starvation (fully used memory).

The trick in optimizing render times is to eliminate bottlenecks, not to create them for the sake of “better” CPU or RAM metrics.
