I have nested and enabled. I find that there are more steps you have not mentioned. I am only able to enable camera 1 and should probably be able to see all cameras. Additionally, I have followed your instructions and simply still do not have a multi-cam edit.
Other tutorials talk about changing the view to a multi-cam edit, but in my version of CC I do not have that option as far as I can tell.
What are the additional steps to convert a normal sequence containing multiple cameras from a normal edit into a multi-cam edit?
