Can't rotate movie (crop tool shaded)

Just moved to iMovie 10 from an old version.

I don't seem to be able to rotate any of my movies. I can select the clip, go to Adjust, but from there the Crop tool is shaded so I can't rotate.

I can select all of the other icons (except the shaking camera). Wondering what I am missing...

This holds for both new and old events, held on my internal and external libraries.

Using OS 10.9.1 and iMovie 10.0.1

Thank you-
