Render queue hanging after clicking render

I am experiencing much improved render times with the beta version of multi frame rendering. Approximately 25 seconds for one of my personal projects I was testing it on, for a comp that would have taken 40-50 seconds on previous versions.


However on a particular composition I'm experiencing a significant delay after clicking 'Render' in the render queue, where the render queue is frozen before the render commences. The actual render starts approx 1 min 20 secs after I click the 'render' button.


Please note I'm not experiencing this same delay if I try to render the AE pulse benchmark project, which commences fairly quickly after clicking render.


Further details about the comp in my personal project:


  • It's a large project file with a lot of external media. The media was loading in from a Samsung T3 SSD.
  • I achieved better results (i.e reduced the time it was hanging) when I 'reduced project' to just the composition in question.
  • Another thing worth noting is that the composition in the original project file used expressions where colours of shape layers were tied to a colour picker in a separate comp. Upon 'reducing project', the links to those expressions were cut (28 expression errors) since the reduce project command doesn't include in comps which are only referenced by expressions.
