Start with what you want to say
Before writing the introduction, finish this sentence: “After watching, I want someone to understand…” Keep the answer to one clear idea. It gives you something to return to when your script starts to wander.
A short video does not have to cover every detail. It needs a clear purpose and enough context for someone to follow it.
Write a line. Say it out loud.
Read your first few lines as if one person were sitting across from you. Notice where you run out of breath, add an extra word, or replace a phrase without thinking. Those changes are useful editing notes.
Write down the version you actually said. Keep contractions and the words you normally use. A sentence can be grammatically tidy and still feel awkward when spoken.
If it is hard to say,
it is worth rewriting.
Give each sentence one job
A sentence that introduces an idea, explains the background, adds an exception, and gives a conclusion is doing too much. Split it into a short sequence instead.
For example, “Our application enables users to create screen recordings while simultaneously consulting a script” can become “Record your screen. Keep your script close to the camera. Walk people through what you are doing.”
Mark the pauses you want
Break your text into small groups of thought. Leave space between an introduction, an explanation, and the next action. The page should help you see where an idea ends.
You do not have to fill every second. A short pause can give a viewer time to look at the screen or absorb an important point. Let your script make room for that.
Finish with the next step
Decide what the viewer should do next. It might be to try one feature, watch another example, or simply remember the central idea. Write that ending before adding another paragraph.
Then read the whole script once more. If it sounds like something you would never say in a conversation, simplify it. The goal is a script you can use while staying present on camera.
