Sev, Andrew Embury (http://yellowlab.tv/) , and I were working on a project using Redshift. For some reason, depth passes from Redshift are true depth passes—i.e. there's no info for focus. The depth is basically colored solely based on distance to camera.
Unfortunately, that means that keeping something in focus inside of After Effects is rather tedious since you can't just select a single grey value and be set. Instead, you have to keyframe the entire sequence so that your focus point is maintained. If you could tell Frischluft (http://www.frischluft.com/lenscare/) or Camera Lens Blur to stick to a point, then you could at least track a spot to keep in focus. Unfortunately, the focus selectors aren't keyframeable. So instead, I built my own workaround, as you'll see in this tutorial.
