Question

APE2021 - low usage of CPU then exporting.

I know that APE depends mostly on CPU, especially when encoding however I’ve noticed that utilization of my CPU is quite low. I don’t understand why Premiere is not using all resources of my CPU. Looks that disks are not limiting the exporting process.

Exporting of 5min clip takes 3h on Intel 9900k. It is 4K project and I’m using 2 pass encoding but still that is very long time and at the same time utilization of CPU is low.

 

Any advices on it?

When I use default preset, even with scaling to different resolution than project, CPU usage is almost 100% and encoding time around 2x longer than duration of the clip.

I know that is the main reason for that very long export time. It is “Render at Maximum Depth” especially in combination with “Shadow/Highlight” effect.

 I used it purposely to limit colour bending which I see in my videos (after export). Obviously I knew that it will increase render time but I still don’t know why usage of CPU is so low then those option is selected.

I can only only make random guesses why those settings slow it down so much.  I wonder what other NLEs might do with those output settings.

What I see does not make sense.   How much RAM do you have?   Are the source footage, project settings and output settings matched?  Is there additional audio?  How complex it the project's timeline?

>What I see does not make sense.   

 

I don’t like it at all, especially that Hardware Acceleration (on Intel) also doesn’t work on my computer. I created another topic about. I’m already tired asking Adobe Support to solve that problem. Now this....

 

 

>How much RAM do you have?

 

32Gb. You can see memory usage in the video in my first post (Task Manager)

 

>Are the source footage, project settings and output settings matched?

 

Yes, they are the same. However, I would expect higher CPU usage even if they were different.

 

>Is there additional audio?

 

Yes. Just single track (music).

 

>How complex it the project's timeline?

 

I would say it is relatively simple. I used:

- contrast: 75

- Image Control/Saturation: 115

- Image Control/Hue: 5

- Shadow/Highlight//Highlight amount:10

- Shadow/Highlight//Midtone Contrast:10

What is the source of the clips?

 

For reference, I use a couple different cameras shooting 4K.  My computer is a laptop with an i7, 16 GB of RAM and an SSD.   I've used a couple versions of Premiere Elements on this computer and a few more versions on a previous and similar computer.   I expect output render times to be up to about twice the length of the video.   

 

My experience is that there is nothing wrong with the software.  Something else is causing your to take hours instead of minutes.
