Simplifying roto work with planar tracking

- Now one of the most useful things…that we can do with the player tracker is…we can use it to simplify some tricky roto work.…So we've seen our clip here,…and let's just set our range between frames 13 and 57.…And we'll zoom into that range on the timeline.…And we'll take a look at what we're going to be doing.…So, I want to create a mask around our boy's face here.…And we've got a couple of problems that should be…immediately obvious.…And they're both related to the fact that he turns around.…You see here.…

So, the first problem is that it's going to be quite tricky…to get a nice consistent shape going on the…front side of the face.…Because as he rotates around,…that front side of the face sort of rotates into this…one small line.…And the other issue we've got is because we have…new areas that weren't visible before.…So we've got the nose and the shape of…the lips and the mouth in profile.…So let's see how much of this we can handle automatically,…and how much we're going to have to do manually.…So let's pick our X-spline tool and we'll create a spline…
