Re: RAM Previews Very Short

if you are working hd, 7 seconds of full res hd is about right... hd frames are big, a 1080 frame is about 6mb, at 30 fps that's about 180mb per second, so 1.26gb for 7 seconds. ae is 32-bit, so the most ram it can use for a single process is 4gb (3gb for a foreground process on osx). ram previews are only a portion of that, about 40%. 40% of 3gb is 1.2gb....

use the resolution/down sampling drop down at the bottom of the preview window to to get longer previews.

to make it easier, you can set the shift-ram preview options to down sample and skip frames to increase preview duration in the time controls panel. so to see longer previews you'd hit shift-zero, to see full quality, or current settings, you'd hit zero.
