Well like I said, I've tried the Motion effect as well as transform, corner pin, and basic 3D, and none of them allow me to do what I would think is something pretty simple. The issue is the perspective of the camera is such that the area I want to zoom to is not at right angles. Here is a frame grab from one of the shots I'm working with:
I want to zoom into the white space on the page, which I motion-tracked and will superimpose a different image on top of. Ideally, I'd be able to "grab" each of the four corners of the white space and drag them to each corner of the frame, and have the whole clip scale/skew accordingly.
I hope you have After Effects.
You can do it there.
I do have AE. How would I go about doing that?
This should give you a boost:
3D Camera Tracker in After Effects CS6
3D Camera Tracker
The 3D Camera Tracker
Thanks for the links, but I had no problem tracking the area in Mocha. My only issue is zooming to the tracked area over the course of a couple frames. Are there any simple ways to do that in After Effects?

I think I may have misunderstood your situation.
I thought you had a camera move to the open space on the book.
That can be matched with the 3D Camera Tracker.
If what you have is a still, it will be very simple to create
a layer in Ae with the content you intend to add to the empty space,
position it as you like in 3D perspective, and move both the
background image and the insert together,
then bring the insert full frame.
Oh... and thanks for contacting Adobe Forums.
Apply CC Power Pin to the image with the area you want to straighten out. (It is in the Distort folder.)
Check the "unstretch" box
Turn the effect off by clicking off the fx. (I know it sounds wrong, just try it.)
Align your four corner points with the distorted portion of the image.
Turn the effect back on.
That should have gotten you most of the way there.
If your white space is not distorted, like on a page that is perfectly flat, it works a lot better.
Joe Bloe: No problem, this is a helpful forum
Steven: That sounds like a simpler solution, so I want to try that first. However, I am using CS6 so I don't have a "CC Power Pin" effect. I've looked, and there doesn't appear to be any sort of "power pin" effect in CS6. Is there something I'm missing?
If I have the corner pin data for the superimposed image in the comp, is there a way of "locking" the same points to the layer below it (so when I stretch out the image the background is stretched with it)? I will also attemt Joe's 3D perspective idea, but I can't say that I'm great in After Effects so that might make for a fun night
Um, oh? The help file says that the Cycore effects all come with CS6. Are you using a trial? Do any of the CC effects show up?
I am not enough of an After Effects guy to be able to help when things go wrong. I suggest you wander over to their forum and ask about the Cycore effects.
Wow...it's been a long day. I had assumed "CC" meant "Creative Cloud," but it didn't in this case
And it worked!! I had to apply the power pin effect to the foreground and background layers separately, but that was exactly what I needed. Thanks so much to both of you!
Ah! CC and CC. Got it. Completely slipped my mind. Sorry about that.
Glad it worked out for you.
Yep! Maybe it won't be such a long night after all
