Every time without fail After Effects crashes when I try to change my render settings. When I'm in Render Queue > Output Module > Click Lossless > Under Video Output > Format Options button. When I try to click the Format Options Button to change from animation quality to like h.256, After Effects Crashes. Below is the Alert message it gives me when it crashes. I have a late 2013 13" macbook pro with retina. I've purged all memory and disk cache as well and still it crashes every time. I can't have 10 second videos being 300 MB so any suggestions?
First, make sure your AE is up-to-date.
Second, you should be rendering your compressed files from the Adobe Media Encoder. H.264 from the render cue and QuickTime is a mess. Don't even try. Apple really found that up.
