When working with large projects inside of After Effects, I often come across a problem with RAM previews. When I hit the RAM preview button, AE kind of freezes up for about 30 seconds or so while showing a white bar filling up with blue under the comp window. After the 30 seconds, AE starts to render the frames and everything goes at normal speed from there. This is just really inconvenient and annoying when I need to preview with sound. Is there some sort of memory setting I should change? Shortening the work area doesn’t help.
