Re: multicam stacks everything in a pile

To expand: to make sure all the clips from the same camera come out on the same layer in the multicam editor you need to make sure that in the inspector, basic view, the "Camera Name" field is filled out. You can highlight all the Cam 1 clips at once if I remember right, and type a camera name into that field. Do that before you make the multicam clip, any breaks in a camera get lined up on the same layer.

If you're choosing "use audio for synchronization" which it sounds like you are, the clips obviously need to have fairly decent audio that the waveforms can be matched up.

I don't think the app gives a darn what your keyword collections are or what you've named the files.
