This is by design.
I checked 2017 and shows the same behaviour.
Want to hover scrub the selected clip just select another clip.
Or ctrl+shift+A will deselect.
Thanks for the clarification Ann!
It seems a weird choice if by design tho right? Surely the benefit of Hover to Scrub was supposed to be a quicker/slicker way to mark in and out points. But from what I can see, I can only mark in an out points while scrubbing on a selected clip (only achievable with the click and drag workaround) so if I can only scrub deselected clips then I can't mark in and out points quickly.
There's definitely potential to develop the Hover Scrubbing feature into something really useful for choosing selects faster!
When hover scrubbing on a non selected clip use I and O shortcut to mark in and outpoint.
Ah that's interesting! That function doesn't work for me. I have remapped the mark in and out to different keys within the Premiere keyboard shortcuts panel. I wonder if that is part of the problem I am seeing. I have to select a clip and move it before I can set in/out with keyboard shorts
If you hoverscrub do you see a very thin blue line (opposite to a thicker blue line when selected) under the clip?
