Earlier quoted context omitted.
I really wanted to like the Touch Bar for scrubbing, but then I hooked up the external monitor and the Bluetooth magic keyboard and... To this day I can not figure out why Apple doesn’t sell an external Touch Bar of some kind, for use by the actual professional video editors out there.
Have you tried a trackball?
To be clear, I’m an amateur at video and I do know there are lots of dedicated tools from scrubber dials to keyboards.
The part I can’t figure out is why Apple has this “pro” tech for which the most obvious and most hyped use-case is video editing, but they don’t sell any version of it a professional video editor could actually use.
