I tried to render two little movie clips I dropped into the timeline to learn how to do video editing in Blender 2.8 and after a minute my computer box started beeping (which it's done once before when I tried mining Monero and it overheated and shutdown).

How can I limit how much damage Blender is doing to my box?

  • $\begingroup$ Hm, VSE rendering was always a single-threaded task, I doubt they change it for 2.8. Any way, you can limit CPU threads in Render tab by switching from Auto to desired number. $\endgroup$ – Serge L Dec 16 '18 at 11:51
  • $\begingroup$ Please would you explain where that setting is, I don't see it in my properties. $\endgroup$ – Richard Dec 16 '18 at 15:17
  • $\begingroup$ It is in Performance rollout, see "Threads" section here: docs.blender.org/manual/en/latest/render/cycles/settings/scene/… $\endgroup$ – Serge L Dec 16 '18 at 15:47
  • $\begingroup$ That's for an older Blender, and a completely different default rendering engine. $\endgroup$ – Richard Dec 17 '18 at 5:56
  • $\begingroup$ But even if I switch from Cycles to EVEE and fix 1 thread my fan still goes wild and the computer beeps. Which doesn't happen when I render video & music with multiple intense VSTs in Reaper, so I don't think it's a computer problem. $\endgroup$ – Richard Dec 17 '18 at 6:04
