I am using MM (2012) Build 16.4.3528.0331

Clip I am working on is just 22 seconds long

I'd like to trim a few seconds from the end of the clip (it's black for too long after the transition fading from video to black.

In any event almost all options in the Video Tools - Edit  (including split, set start point, set end point) are grayed out and cannot be clicked.

OS Windows 10.  

Thanks for your assistance.
