This question already has an answer here:

I use Blender as a video editor.

After setting up the video I want to process including correct Start and End frames I click "Properties->Render->Animation".

My CPU usage climbs to a range from 20% to 25%. I am running an i7-3770K @ 3.50 GHz with 32 GB Ram. Blender is working on a physical drive, not an ssd. The i7 has 4 cores. With hyper threading that is 8 Hyper threads. I think Blender is running animation on only one core.

When I try to research this topic I get a mixed message.

I can find performance analysis multi core vs single core. I can find a Microsoft demo how the job queue can be executed parallel on a cloud service.

I can find entries that say the Renderer is multi core the rest is not.

But I can not find the settings to enable my animation to be multi core. I assume this is possible since it looks like it is part of the Renderer .

Is there something definitive like an official source on this?
How do I set up my Renderer so that It utilizes all (or most) of my machine?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ When you say "After setting up the video I want to process" does this mean you are using blender's video editor (VSE) or are you rendering a 3D scene? $\endgroup$ – Ray Mairlot Oct 15 '16 at 16:45
  • $\begingroup$ @RayMairlot Setting up the video means that I drag and drop an avi file onto the Video sequence editor. When that is done I change the endframe to fit the video. Other settings were stored in my preferences. Not sure if that is the VSE Editor or not but it is not a 3D Scene. $\endgroup$ – Johannes Oct 15 '16 at 16:51

It seems like the current VSE targets in the road map do not include multithreading. That may change in the future.

The underlying issue of slow rendering is solved in this thread.
