Video Track Timebase

Is it possible to set video track to musical timebase? When I make tempo changes before the video starts - it slides away because it’s fixed to the time, not the bar! And I want it to be at exact bar. Any ideas?
I’m on 10.5.

Can you find the timebase icon on the track or in the track control setings -then yes, otherwise obviously no.


The Toggle Timebase button is not available for Video track.

Now that was simple…
