Question

After Effects and Media Encoder take 2 hours to render 30 second 1080p clip

A while ago it took even 8 hours, but that was due to no GPU acceleration. I managed to get the option to show up on AME, but that only lowered it to 2 hours. CPU usage also rockets up to ~90% while doing so. For reference, I'm using a GTX 1060 and an i7-7700HQ. I've tried adding the GTX 1060 to the list of cuda-supported cards, but that hasn't affected the render time at all. Updating the drivers both manually and automatically has also affected nothing. Not sure what could be so intensive in the clip as to make it take this long to render. The clip itself only has an audio spectrum to react to a music file, some glowing text displaying the name of the song, a progress bar and a timer. A picture in the background has a Lumetri color effect put onto it as well. I've also got a clip of rain on a window overlayed on the top to make it look a little nicer. Still very, very confused as to how this could lead to 2 hour or longer render times. I rendered an earlier version of the clip a while ago and it took around 45 minutes. This was without the audio spectrum or rain.

Anyway, I'm really confused and not very smart. Any help would be appreciated. Thanks.

    Try to check the renderer you using! Try to not use the Ray-traced 3D!

    Not sure what you expect. Half the effects you mentioned don't use any form of GPU acceleration and the other half do use GPU acceleration in a way that may compete with AME's own use of GPU functions, hence you eventually will run out of resources and the encoder switch into quirks mode. On top of that the usual limitations of any DynamicLink-based workflow apply like excessive memory consumption. There you have it. Unless you take a massively change your approach to this, it won't change. I.e. it might be smarter to render directly from AE and then encode a H.264 for upload later in AME.

    Alright. I'll definitely try changing my approach, and thanks for the specification on other things!
