Burnt in timecode on video on/off? Cubase 10.5.12 Catalina

Ive never seen BITC on a Cubase video before (unless it actually is burnt in) this of course isn’t actually burnt in, just superimposed.- and it’s quite a nice feature to have.

But not all the time.

Is there a way of turning it off?

This has only occurred since updating to Cubase 10.5.12 and Catalina - I am making the wild assumption this has something to do with the use of one of the later Quicktime players because I didn’t see it with 10.5 in High sierra
