Familiarize yourself with the format of television scripts. Read as many samples as you can to learn how to properly format your video news release script.
Write a narrative version of your video news release first. Describe the scenes and use dialogue as though you were writing a short story or a newspaper story about the content of your video news release. This will help you lay out the direction of the final work and polish the content.
Create an outline from your narrative. Make a list of the various camera shots that will make up the final work. Make a list of all the spoken dialogue from your narrative, separating the lines by character.
Launch your scriptwriting software. Build the final script for your video news release using the camera shots and dialogue elements you have already identified. Use standard formatting to identify particular shots and speakers.
