How to Do It
Decide what the caption should explain
Use captions for step names, product labels, speaker names, quick notes, warnings, or context that viewers need while watching.
Place text where it is easy to read
Add the caption away from important faces, buttons, subtitles, or visual details that should remain visible.
Set timing for each note
Make sure captions appear long enough to read and disappear when the video moves to the next idea.
Preview on the expected screen size
A caption that looks fine on a large monitor may be too small on a phone, so preview before export.
