Question

Rendering/Exporting using too much CPU?

I'm a super noob, and I don't want to break my fancy computer.

I started with some footage in Premiere Pro, brought it into After Effects, added a green screen key to every clip of the footage, like 10 cameras (one for each, because noob and don't know better), and two layers to be a 3d background, and a light. So, I understand that rendering is going to be a long process. After Effects kept crashing so I took the composition to Media Encoder, chose my format, and pressed start. My computer's CPU use shot up to 3.5/3.3GHz. And I stopped the render after a few minutes and it hadn't rendered at all.

I might be worrying too much, but the footage could take hours to finish rendering and I don't want to leave my CPU that hot for that long.

    Rendering time aside, don't worry about your CPU getting too hot - it has built-in throttling logic to slow down the clock rate if it gets too hot. That's likely not happening either so I wouldn't sweat it.

      That makes me feel better. Thanks.

      But 60 hours for a 1 minute clip. There has to be something I'm doing wrong.

      Well, you are using Raytrace 3D, do you not? It definitely looks that way from your screenshot and the AME preview. In that case this would be normal, since it runs on the CPU inside AME and GPU support is disabled. You have to turn it off or render directly from AE where the GPU may actualyl work.

        If you're just doing a simple key, try Ultra Key in Premiere Pro. It does a great job. You can create the background in AE and just bring that into Premiere.

        If, however, you need to use AE, we will need a lot more information in order to help you.

          Thanks

          I intended to give more information but it posted before I was done and wouldn't let me go back.

          I'm using a custom PC. CPU is Intel i5. 3.3GHz. 16 GB RAM. The program is on SSD Footage is on HDD (idk if that makes a difference).

          I'm not sure what other information you could use. Let me know if you have any suggestions, though.
