After Effects background rendering isn’t always necessary but it can make your life a lot easier. And with Adobe Media Encoder, which is included in the Adobe Suite, you can do it in no time.
How it works
The way that Adobe Media Encoder can read your After Effects project file is because of Adobe’s “Dynamic Link.” The dynamic link essentially connects programs in the Adobe suite together, so if you wanted to put the After Effects file that your working on into that edit of yours in Adobe Premier you can do this without rendering anything out. The goal of this is to cut out the render time and extra render files that would come up by bringing these files into each other.
To render your After Effects file in Media Encoder all you have to do is drag and drop your After Effects project file inside of Media Encoder. Simple as that. You can pick and choose how you want to encode it and how many different ways you want to encode it. It will render it in the background and you are free to do whatever you want back in After Effects with a somewhat minimal performance hit. Keep in mind that this is just a background render so it isn’t going to render faster than it would straight out of After Effects, in fact it will take significantly longer – How much longer depends on what else you are doing in After Effects or any other program. The Adobe Suite programs communicate with each other and depending on what you are doing in After Effects the Dynamic Link between them will allocate either more or less memory to the background render of Media Encoder and attempt to give you a smooth experience in AE (or other adobe programs) while still rendering. So basically the background render is low priority memory wise and the dynamic link will give you more power in After Effects to do what you’re doing which will in turn make your background render take much longer.
