TV News works a little differently. Let’s talk about a reporters’s package.
1) You need the anchor to introduce the package.
2) You need the reporter to write and deliver the package.
3) You need the photographer to shoot the video for the package.
4) You need a video editor to edit the package.(sometimes the photographer does this)
5) You need a producer to determine when and how the package will be played.
6 You need an engineer to be sure the package is played at the right time.
7 You need a director to tell the engineer when the package should be played.
8) You need a graphic artist to design and produce any graphics that will be used in the package.
9) You need a person to type and play the “supers” for the package (these are the name and their title that often appear near the bottom of the screen).
10) You need someone to run the telemprompter for the anchor
11, 12, 13 — You need three camera people in the studio to operate the cameras in the studios that shoot the anchor.
And there’s probably at least one more person I’ve forgotten or don’t know about, since it’s been a long time since I’ve worked in TV.
TV newscasts aren’t rehearsed. But it takes a lot to produce them.
It’s actually less than that, especially in smaller markets. Now an anchor, who may or may not be the reporter, introduces the package which may or may not have been produced, shot and edited by the reporter himself.
In small markets, the anchor is often the producer as well. Graphics are done by a separate person, but anchors can now operate teleprompters themselves and in larger markets, studio cameras can be computer controlled (I know of at least one top 15 market affiliate that does this with regularity).
