I have some video footage that contains some "private parts" that my director would like me to gently blur. I recall a tutorial on this--I think it was blurring the face of someone in witness protection--but I just don't remember the actual techniques. Rotobrush perhaps? Some guidance here would be most appreciated before I launch off re-inventing what is probably a well-established wheel

Hmmm, maybe duplicating the footage and applying a camera lens blur or something, and drawing a mask around the desired area, and probably keyframing the position, or if you have CC 2015, then tracking the mask.
"It's all around us Neo, temporary constructs of time....."
track the private parts area, link track data to a Solid layer that has a feathered mask drawn to create a shape that covers the area you need to blur, then use that layer as a track matte on a Adjustment layer that has a blur effect applied to it.
