After Effects not using CPU even when simple video conversion.

Hello everyone.

 

I'm very new to this forum and this is my first post. the reason i'm here is because I am confused about something which I hope someone could solve my problem.

 

When I export the video (which is 4K in this example) from Premier Pro, it utilize the cpu well and it takes 4 minutes to convert the video to H.264 format and anything default matching the source footage.

 

now if I do the same with Adobe Encoder, it behaves the same and utilize the cpu well and takes almost same time to convert,

 

but the problem is if I use the same video in after effects, create new composition from the source file and do nothing else but just export it to Media Encoder and every settings is the same as with previous example. It takes more time almost 20 minutes and it is using CPU 40% to 50%.

Can someone please guide me telling, what is wrong with the After Effects?

 

I have read many forums telling that AE is more complex and it has to do computations, but my concern is that, Im not using any effects or else, am jut converting the video, and isn't it logical that the same video should take the same time to convert?  or at lease it should utilize the full CPU, because if its only converting the video file, it should only depend on CPU.

 

my PC is (in my thinking) capable to handle this kind of job,  i have build it myself with following components.

 

Asus X99 gaming mothorboard.

intel i7 6800k CPU

Samsung 500GB Evo M.2 SSD on PCI x slot.

EVGA GTX1050 ti  GPU

windows 7 64bit ultimate

After Effects CC 2017

Premiere Prp CC 2017

Media Encoder CC 2017

 

also note that it is not about 4K video or anything. This problem is there even if I use any video file of any resolution or size, The difference and AE not utilizing full CPU.

 

please help. Thanks
