Someone has to sign off on what the video says: an SOP, a policy, a safety step, a manual. You need to show where each line came from.

You want a whiteboard video fast and won't check it line by line against the document.

You are studying your own notes and want a quick overview to watch or listen to.

You want a summary, a quiz or a script in text. It does not make the video.
