I have a comp that has been RAM Previewed and consequently, the entire status bar above the timeline is green.
However if I take my playhead and drag through the timeline, the screen updates very very slowly (perhaps 1~2fps). But I can RAM Preview at full speed.
Any ideas? I thought once it's cached, and you aren't changing any parameters, it should scrub through because it's all loaded in RAM, yes? I swear I've done this a billion times in the past.
48GB Mac with 10GB free for other stuff. 200GB HDD Global Cache (although nothing in the status bar is blue. It's all green)
You may be using a specific plug-in/ effect/ feature that continually requests temporal information. Could be by design, could be intentional. also, naturally, expressions will get in the way of cacheing operations many times...
Yup! Expressions is what's killing it. I have several LinesCreator 3D lines which uses copious amount of code to do its magic.
Shake 'n Bake those expressions!
If you post the expressions that are causing the slowdown to the Expressions forum here we may be able to help. Sometimes it's easy to get a loop going that has to go back and re-calculate every frame for the next one. These are render killers.
