Simple Render suddenly takes hours to render?!
on Jun 23, 2015 at 9:20:41 pm

I have a 2011 IMAC Pro. I have always had pretty good render times. It has been a month or two since i opened up after effects at home, but a simple particle world fire animation with a 150x150 texture size is taking me 3 hours to render. sure it is a 3 minute video, but it looks like a 30 minute render tops. Any tips?....besides getting another computer!

try cleaning out your disk / memory caches and export it to a separate Hard Drive than the one the file is saved too. Sometimes that works for me.

If you have an SSD in there, try saving it to that.

Hi Derek, Should the Conformed Media caches on the same Hard drive?
thanks

...and it depends on what you're doing, too. Remove Grain, for example, slows down AE renders to glacial speeds.

What are your system specs and multiprocessing settings? Are you accidentally working in a Ray-traced 3D comp instead of a Classic 3D comp?

Hi Walter, don't know if your question is addressed to me or to Richard but as I have sometimes the same problem your advice would be welcome. I've already changed the location of cache file and nothing else. Here are the infos you ask for:

System


Video Card and Disk and drivers


Media disk cache settings in AE CC2014 latest update


Memory and multiprocessing settings


I haven't tested yet the change of the effect of the cache location. But yesterday I had a rather heavy project to render and it took 6 hours! Even for a retired banker this is a bit long !!!!LOL!
You can watch the vidéo here:
Thanks in advance for your recommendations

Claude

Maybe try reserving a little more RAM for other applications.

I took out some parts, cleared my ae memory and my render times were much better thanks. I don't know how i forgot to clear the memory.

[Richard Garabedain] "I took out some parts, cleared my ae memory and my render times were much better thanks. I don't know how i forgot to clear the memory."

You should not have to manually purge memory before starting a render. In fact, if you're previewing at the same resolution as you are rendering, NOT clearing memory should speed up your final renders as Ae will hold final frames in its green-line RAM cache.
