Build the judgement before the automation.
The first video teaches you things no amount of planning will. Where your process breaks, how long editing really takes, what you sound like, what the upload screen actually asks for. None of that is knowable in advance.
Choose a subject you could explain to a friend without research. The goal of video one is to complete the loop, not to make your best work — the ambitious idea deserves a creator who has already been through this once.
Set a hard scope: one question, three to five minutes, one location, no graphics you cannot make in an hour. Scope is what turns a first video into a published video instead of an abandoned folder.
You still need the non-negotiables even at this size: check anything you state as fact, have permission for any music, footage or person you include, and disclose AI where a viewer could be misled about something real.
Publishing is a decision with a checklist, not a mood. Title, thumbnail, description, visibility, the altered-content question, and one last watch of your own export before it goes public.
