Aren't you double posting the same question? There's more system info here but no project info. It sounds like you're using the space bar to preview. That's the wrong way to do it. Use the Preview Panel and click the ram preview button (far right) or use the 0 on the Numeric Keypad or use Composition>Preview>Ram Preview from the menu.
Your open GL card won't help with anything but Ray Traced rendering in CS6.
Well, project info:
1920 x 1080, 24fps, HDTV 1080 24 Preset.
One clip filmed with Nikon D800 (1080p@24), 16 seconds long
Added two shapes (very thin lines), one text, one "Solid Layer" for vignetting, and then Nul for tracker which is for the lines and text.
All the Effects are in the videoclip: Sharpen, Levels, Broadcast Colors, SA Color Finesse 3, Unsharp Mask
I've used Numpad 0 almost all the time for preview. But is the space bar preview for previewing AFTER numpad 0 RAM-preview, because the RAM preview makes the green line over the composition. But if the most of the preview is done by NumPad 0, what's the meaning of the space button -preview in the After Effects when it seems to be a wrong way to preview.
Is there any way to improve this preview? More RAM, faster CPU?
Is there something I should upgrade or change in my hardware?
- Add a SSD for cache?
- Better and faster disks for my footage?
- Faster and better CPU? (maybe two CPUs, Xeons?)
The RAM-preview for 16 seconds long clip with pretty few effects (roughly 3 effects and three solids) takes about 4,5 mins to complete. I find this bit too slow because this might be a major problem if I do a longer videos where I need to use After Effects more. Especially if I use dynamic link, that would be a major problem.
What kind of hardware would be perfect for After Effects?
This had happened to me, I had decided to fool with the settings for a small amount of time, I had the preview open so with the preview area open (on the side) under the play button you will find a skip button thing, (it is beside frame rate and resolution) click that then set it to zero. That fixed it for me. I hope it helps!
