So i've been working on a project and wanted to render it out. I already had a very similar project rendered before all that which didn't prove difficult for my pc at all. AE estimated 20 minutes for my current project when suddenly (the video was approximately half way rendered) only one frame every 2 seconds was rendered (before it were about 3 per second). The estimated time went up until after one hour it estimated 1 h 50 min.
I cannot understand it since there are no changes in the project at the point where it slowed down. It was exactly what was rendered just a moment ago. I haven't opened any new applications during the rendering. Also i've checked my task manager and all the other things required barely any CPU or RAM. I've never had problems with extreme slow rendering before.
