How do I reduce the size of all elements in a Motion project proportionately and simultaneously?

Question

I have created a complex Motion project with many elements.  Does anyone know how to reduce the size of all elements proportionately and simultaneously in order to shrink this down to a corner logo? Thanks

Answer 1

Sure.
In the Layers pane,  IF all of your layers are already in a single Group (if you're really a beginner, then you probably just have the one group), all you need to do is select the Group "layer" containing your design elements and clone it (type - k) -- you'll get a new layer in a new group if it's a top level group of the project called Clone Layer.  (If you have more than one group, select all of them --- however, if there is an FCPX Placeholder-drop-zone-looking-layer with a label like Effect Source or Title Background, don't select that -- you'll need to command-click select just the layers that make up your logo design). [You can alternately select *everything* and command click the layers you do not want to include in the Clone.]
Creating a clone of anything in no way changes that object or objects.  A clone is like a composite viewer for objects/layers -- like a tv screen is to broadcast signals...
Uncheck the Cloned Group (or selected objects - if still selected, unchecking one will uncheck all of the selected layers) to inactivate it (this will not affect the clone visibility.) 
Select the Clone Layer.
Use the Properties > Transform tools to scale and position the clone layer (changing the blend mode to something like hard light, overlay or similar, and adjusting the opacity makes for a nice "watermark" [corner logo]).
HTH (hope it's clear enough!)
