It would probably make more sense to render a Quicktime file from AE and then quickly convert it in AME. The rest we can't realyl know since we have no info on the details of your project, your system etc..
CPU: intel i7-4770 3.40GHz
graphic: NVIDIA GeForce GTX 650 2GB
What project details do you need?
I've been working on the same computer before, but used older versions, and it worked normally. I have never worked with AME, since I always exported directly in AE, but where could I go wrong?
As Mylenium says, try rendering a QuickTime (with the Photo-JPEG codec or the PNG codec) and then use that file in the Adobe Media Encoder. That way you are rendering in AE as you remember doing, but can use AME's superior H.264 encoding.
does your composition include Ray – traced rendering? If it does that is the source of an incredible slowdown in rendering.
No "Ray traced rendering" in my composition. Tried everything you guys suggested but nothing worked, so now I'm just exporting everything through the night. Thanks anyway
