Two-Column or AV Scripts are as their name implies: as script split into two columns: the first for everything visual, and the second for everything audible. AV Scripts are typically only used for multi-camera productions as well as advertisements, corporate and instructional videos.
What are three key things to remember about formatting an AV script?
1. The Header
The header of each page should begin with the page number followed by a period, and then any relevant information to the client. This information can include titles, slugs, names, dates and so on. I also recommend listing the version of the script in the header and keeping an archive of old versions, in case a client wants to return to a previous AV script.
The columns, as stated earlier, are split into two categories: audio and video, audio on the right and video on the left. Each column should begin with an "AUDIO" and "VIDEO" video above them, and the shots and corresponding audio should always be aligned horizontally.
The video column should contain the shot size, the subject, action or blocking notes, special camera movements and other descriptions for each shot. The audio column should contain any dialogue (with the characters speaking it), music and sound effects. All text other than dialogue should be written in capital letters.
