The project includes a lot of text and fade ins and outs and looks perfect in the playback.
How are you playing it back in AE? Are you doing a proper RAM Preview by hitting the zero key on the numeric keypad?
But once I render and playback with Quicktime the video does not look the same. The animations are very jumpy.
A similar question applies: how are you playing back the rendered AE file? Can you elaborate on the term, "jumpy"?
What's the frame rate of your AE comp? What's the media container and codec of the completed render?
Baswed on your description, I'd say the most likely answer to your delemma would be this:
I have been using the Standard RAM Preview on after effects. The settings that I have it on are 29.97 fps, Skip 0 and resolution auto. The playback in AE would never completely reach real time though. I am sure that is common though with a laptop speed. I exported with those settings and then played it back and all of the keyframes that looked smooth in AE were not as smooth and were a lot quicker when I played back with Quicktime Player. I wasn't sure if it was the export settings so I re-exported with a 9 sec fps, since that seemed to be the speed of the playback in AE. When I played that one back in Quicktime the keyframes jumped even faster. My question is do you think that my keyframes are too quick or is it my export settings? This is my second time using After Effects for a project and is the second time that it appeared correct on the screen, but when I exported it didn't seem to be as smooth.
If it matters, I am using a Macbook Pro Retina Mid 2012, 251 GB with Yosemite OSX.
Also, my AE comp is 29.97, but i have four other comps in that one and they're 23.97 fps. Those comps are the one's that jump the most. Is this the problem?

Open the Info panel, and then do your RAM Preview. If you're just clicking on the "Forward" icon, it's not a proper RAM Preview.
And y0u really need to look at that FAQ link.

It seems like that would be the likely culprit. Is there a specific reason those comps (which are, I assume, nested inside the 29.97 one?) are 23.976? Do they contain 23.976fps footage? Mixing of comps, video and different frame rates can often cause juddery playback after rendering, as the interpolation of the frame rates to the master render frame rate happens without any interaction on the user's part. But AE gives many different options (and techniques, everyone has their own) to assist with getting the frame rates and speeds more aligned so the final frame rate is perfect for them all. It takes a little planning, that's all.
Let me know, I'll be glad to help if this is the issue.
