I get this error constantly, and it seems completely randomly.
Purging every time I have to do a RAM preview for a client is ridiculous.
Also it seems that sometimes the length of my ram previews get shorter and shorter.
On a brand new MAC with 8gig ram I should be able to preview more than 4 seconds on a SD comp.
No footage involved just PSD and AI, and AE solids, shapes etc.
I just quit and relaunched AE now I can preview the full 10 secs.
It’s very hard to pin down what is causing it.
Thank You
