To maintain this type of non-obvious editing you need to be consistent with certain visual elements of your clips so you do not interrupt the narrative flow of your video. Make sure that when selecting clips, or choosing which ones should be paired up, that you do not violate the “180 degree rule.” This rule states that everything should happen on a 180-degree strait line, and you should never jump to the other side of that line as a viewer. This means that if someone is on the left side of the screen watching a television that is on the right side, the next scene should not have him or her suddenly on the right side of the screen watching a television on the left side. It is great to have slight changes in angles when mixing the shots together, but nothing as dramatic as completely changing their position on the screen.
