Output to the render of After Effects CC 2018 in the Media Encoder СС 2018

When outputting to the Media Encoder SS 2018 from After Effects CC 2018, the Media Encoder SS 2018 loads files for a very long time and the render takes place twice as long. With the connection to Premiere Pro CC 2018, there are no such problems. Why is this happening. Sorry this is machine translation.@
