After Effects 2024 slow rendering even when comp is fully cached to ram?

Just wondering if something is going on and whether I'm missing something here. My comp caches to ram pretty quickly and 'pre-renders' in AE. However, when I hit render on a sequence from the queue - in this instance a PNG / JPG sequence - it takes ~25minutes to write out 360 frames.

 

The PNGs are about 5Mb each. The footage is FHD. I swear in older versions of AE this would have exported out in minutes due to it being cached already. I can't understand why it's taking so long.

 

Anyone have any ideas? 

 

Thanks in advance!

Scroll down to "Don't use PNGs".

 

The article also gets into writing a frame from a cached render versus rendered from scratch.

How does the render time compare if you queue the Comp up again but use TIFF instead of PNG?

Wow, yes, the TIFFs are pretty much instant whereas the PNGs take way longer Jordan366164316x0e_0-1717486681615.png

I just don't remember it being this slow before!

just tried JPEG too and they're a similar speed to writing the TIFFs (6 seconds)
