This sounds more complicated than it actually is in a practical situation, where the entire process is usually done in a single day. For example, if there is a story about a drug recall, you have a few different things to do. First, you need to get as much governmental information as possible as well as information from the company selling the drugs. If you can, you will do quick interviews with both representatives from the FDA and the company.
Then you will get footage of the drug being manufactured from the company. You will go ahead and get your own location footage of places, such as the company’s headquarters and pharmacies where it might be sold. The additional interviews should be things like users of the drug who may be worried or drug store owners that are going to be financially affected.
Now, you will finish a voice over that tells the story similar to a news feature, giving audio blank spots for interview clips. Once the VO is recorded, go ahead and edit them all together into a few minute spot. The video is then given to the producer of the live news program and then is run during the live news cast.
