Question

aerender.exe not use "Multi-Frame Rendering"

I use After Effects 23.4.0

The problem is, after the latest updates, I won’t say for sure from which one, aerender.exe 

stopped using Multi-Frame Rendering, i.e. render happens as in After effects with the option turned off  "Multi-Frame Rendering". Flag in aerender.exe - mp, does not help.

i.e. rendering does not go several frames in parallel, as it should happen, and how it happens in After effects, sequentially, as with the option "Multi-Frame Rendering" turned off.

Has anyone encountered or noticed this problem?

I think I answered my own question, and maybe yours:

 

"-mfr mfr_flag max_cpu_percent"
where mfr_flag ("ON"|"OFF") specifies if Multi-Frame Rendering should be used, and max_cpu_percent (1-100) specifies the desired maximum CPU percentage power to use during rendering. Because Multi-Frame Rendering has the ability to use 100 percent of your CPU's capability, you may choose to limit the CPU power so other applications can be used. max_cpu_percent will be ignored when the mfr_flag is set to "OFF"

I'm trying to use this with rendergarden, and it's failing. Seems like the right idea, but the command isn't recognized.

I'm sorry, this doesn't answer your question, but-- do you know if there's a flag in the command line that disables MFR on purpose?

    Without any specific info about your system and the contents of your project(s) nobody can tell you anything. For all we know you are simply using a specific effect that is not MFR-enabled and then things switch to single core rendering. You need to be much more specific.

    In the after effects itself, everything works fine, read my post carefully, it stopped working in aerender.exe a few updates ago. What about my system or project? nothing has changed except for the after effects version
