Over here I film a coking show and there was some situation where I had to step inside the frame of the main camera for filming B-ROLL as you notice from the video I had to remove myself from the final film and the easiest way was to use a mask in the editing program. But these kind of shoots need to plan before and you have to take in consideration many aspects and I have to explain to the client the way I have to work and how I'm going to fix, in this case is the classic saying ''will be fix in post''.
