Well that depends if the filmer is the editor as well, man.
I've cut out rollaway before. Who needs it.
Oh I can roll on my board.. I can real switch roll away too. I'm a good filmer.
and I have seen people do it
Fading from one clip to another is just another way of doing it
Some people gradually have the camera look to the floor or to the sky
but really what you're doing is cutting out the rollaway for an easy video transition.
Stop hatin. Yoloolololol lol
