So let's say I have characters A and B who are chatting about a video that Character A recorded of themselves. In between their chatting, the dialogue of the video can also be heard, for example:
"Hey look at this... why isn't it working?" said Character A.
"You didn't press play," said Character B.
The video started to play, "Hi everyone, my name is Character A and this is..." said Character A in the video, taking the audience through a tour of the house.
"You sound really stupid Character A."
"Yeah well maybe you should do it next time then," said Character A, getting touchy.
So essentially I have treated the video as another character, even though it's a recording of Character A. Are there any format guidelines for this sort of thing? In the case where there is something important in the video, I need the content to come through as well (both audio and visuals), if that makes sense.
