Track mask hack with FCPX 10.6

Hi everyone, this is a simple hack to track mask inside FCPX:

- put the clip with the object to track in the timeline
- track the object that you want to mask
- Overimpose/connect a solid white layer, same length of the object's clip
- change the anchor point of the solid layer: center the layer on the center of the tracked obj
- draw the mask on the solid layer
- apply the tracker at the solid layer
- change the composite mode of the solid layer in "stencil alpha"
- make a compound clip with the solid layer and the objects clip

enjoy

ok, so that's a way to track any mask .... (like a Draw Mask) (So far tracking works with effects  Mask only.)

Great trick.
