Media scriptwriting: give every scene a job
A usable script shows what changes, who needs to know and how the audience will see or hear it.
State the premise
Write the protagonist, obstacle and possible outcome before polishing dialogue. In factual work, use a verifiable question and explanatory arc instead. Outline scenes by purpose: introduce, demonstrate, challenge or resolve. If two scenes do the same work, test whether one can go.
Write for the medium
In video, do not narrate what the image already shows. In audio, supply context a listener cannot see. Make changes of place audible or visible. Read aloud and time the draft without rushing. Label verified facts, quotations and reconstructions so production cannot confuse them.
Revise with a reader
Give a draft to someone unfamiliar with the subject. Ask what they understood, where they hesitated and what they expected next. Fix structure before adjectives. Track versions and requested changes. A documentary revision also has to preserve accuracy and the rights of people filmed.
Try it
Outline six scenes for a four-minute video. Beside each, name its question and required evidence. Remove one scene and test whether the story becomes clearer.
Before publishing
Label reconstructions; invented dialogue cannot be presented as documentary testimony.
