I don't really know how to describe it, so here's an example of what I am trying to do:

http://www.youtube.com/user/hbmcreations#p/u/3/yd7DQ61hJbw


I tried making a solid where I use a keyframed mask to reveal it, but it got tedious trying to match up a new solid in 3D space every time I wanted to change direction. I know some Trapcode plug-ins might be helpful, but I don't have any plug-ins outside of Video Copilot stuff. It seems like it should be fairly easy and straight-forward, but I've used AE for over three years and am stuck on something so simple. Any suggestions?

Go and check out videocopilot.net - Andrew Kramer has a free plug in and tutorials there that will show exactly how the You Tuber did it and more :)

I've looked up videocopilot already with no luck. Would you happen to have a specific link or plug-in name?

Thanks for the response, btw.

It isn't a plug in it is a set of presets called Sure Target that allows you to move between the 3D targets in the fashion shown there. Andrew has a bunch of free tutorials on the site and the Sure Target presets are free as well. Much of the other stuff on You Tube vid is lifted straight from the Sure Target tutorials, but the actual wipe itself is probably the simplest part - I think it is just nested in the target layers themselves.

Ok, I've used Sure Target before. For me, the camera movement is simple, it's just the wipe that I'm having trouble with.

Hi Daniel

Have confess I didn't look at the whole thing that closely the first time. It looks to me like he's built all the black solids and framed images in 3D space using the camera before he started and then mapped out the move between targets using SureTarget.

So the actual position and orientation fo each of those targets is actually dictated by the way the black solids track through 3D space.

It's neat and i don't iamgine there are many shortcuts - you just have to create a bunch of black solids and startlinking them at 90 degrees in various directions in 3D space and place your targets along the same path....

Thanks for that. That's what I started doing. It actually isn't as bad as I thought, though once in a while the bars just don't want to align. But so far, so good. Maybe I'll post the final product when it's done.
