Plain screen recording for technical buyers

Give me a step-by-step plan I can follow this week, for a short video about [your product], for [your audience]. The technique is plain screen recording for technical buyers: it looks like a user showing a tool, which is what this buyer trusts. How it works: a plain 9:16 screen recording of someone using the product, 30 to 60 seconds, one line of text on top. It is right for: ads for developer tools and products bought by older or technical people. A practitioner's claim from one programme: for technical or older buyers the plainer ad performs better. He also says a paid winner can rarely be planned; keep the bar to run an ad low. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
