Adding a cupcake or sensor over footage in FCP

[Michael Lynch]

One way is to import your cupcake image or create a black box via Effects>video generators>Shapes . Place your shape, cupcake whatever, on the track above the main footage, size an position accordingly via the motion tab.

Here’s where it gets a bit tricky – you’ll need to keyframe the position of the shape to follow her movements via the center function within the basic motion area of the motion tab. If she doesn’t move much it will be easy, if she moves a lot – more keyframing for you.

Someone may have an easier way, but this will work Let me know if you need more info.

Just duplicate your layers (Option+shift). Crop down to the offending area (Motion tab>crop>l,r,t,b). Add a filter such as blur or whatever you want. Render and done. Since the cropped video is identical it will always the cropped area will always follow the layer below. Easier than keyframing.
