Join Richard Harrington for an in-depth discussion in this video Saving RAM previews, part of After Effects Guru: Faster Previews and Rendering.
Let's say you've gone through a composition, and you've successfully RAM previewed it. Sure, if you're using the performance disk cache, those frames can be stored on your hard drive for easy access when the client walks back in, or if you want to make a few tweaks and jump between comps. But what happens if you want to share that with somebody who's not in the office? Or maybe you're very happy with it, you want to save that draft quality or even close to final quality preview as a movie that can be posted or easily shared. Well, fortunately, After Effects has the ability to sort of, retro-actively invoke a render and store those frames.
Lets switch here to the composition that has been RAM previewed. This particular comp has been entirely previewed at full quality with all frames and everything looks pretty good. I want to save that. If I click on the composition menu, you'll see the option to save a RAM preview. The shortcut is control+zero on your numeric keypad. In order to use that shortcut, it won't work if you have got the project panel selected, but if you have the composition window or the timeline active, pressing control or command+zero on the numeric keypad will bring up the ability to save this.
And note, it's not quite as full featured here, you're only going to have a choice of saving it as an AVI on a Windows machine or a movie file on a Mac. But when you click save, all of those frames that you have written to date just get written to a file on disk. It essentially invokes a really quick render in the render queue. And it's able to reuse what you already had stored. This really comes in handy as a quick way of getting things out. So in this case here, let's do the Shift RAM Preview and that's already done through with this file.
It's done every other frame at half quality. Well, if I choose Composition, Save RAM Preview. It adds it in and writes the file pretty quickly. Let's take a quick look at that file and see which one it wrote. There it is and if I press play I see that it doesn't actually have any duration. It's only one frame. Important gotcha there, you need to realize. While in After Effects, we had used to Shift RAM Preview to invoke a draft quality preview.
The real RAM preview had only written one frame to disk. So when I have chose to save that, the Save RAM Preview uses the original RAM preview option. Not the alternative Shift RAM Preview. So make sure the one you actually want to save is loaded, which is going to be the RAM Preview, which you invoke by clicking on the Preview button without a modifier key.
