After Effects is rendering absurdly slow
I am having problems rendering my project. At half resolution which I was doing for drafts, the render time was around an hour. Now that I am trying to render out the final version at full resolution, it is estimating 31 HOURS and taking OVER 2 MINUTES PER FRAME. I have tried every variation of render settings but cannot seem to get it to speed up. I was somehow able to get it to an acceptable speed this morning with a render time of 6 hours, but AE crashed halfway through, and now I can’t get it back to a sane number. I’m exporting a PNG sequence, so at least I can continue the render where I left off. Any ideas as to why my render is taking soooooo long? It doesn’t make sense that rendering at full resolution rather than half would make the render time jump that significantly.

Some information about your system and your project would be very helpful.
Without any other information, I’d guess that you’re either overscheduling your processors or starving them of RAM. If you’re using multiprocessing, I’d suggest you either turn it down, or turn it off entirely.

In addition to Walter’s advice I would see if OpenGl is on- turn it off.

My project had a lot of comps and high res assets. I think the longer render times it was estimating were a result of After Effects hitting a particularly processor intensive part of the animation. I cut the motion blur samples by half and just let it render and the time slowly crept down until it finished eventually around 4 or so hours total. I had already tried every render setting, rendering multiple frames on and off, allocating more and less memory, opengl on and off, etc. In the end, I think it is just time for a new machine.
