How these zones are set
These are the same margins Wavemaker uses when it places captions on a vertical video and when it reviews a finished one. Each app draws its buttons down the right edge and its caption, account name and controls along the bottom. The Reels zone also keeps clear of the call-to-action button that ads add. Apps move their buttons from time to time, so treat the box as a margin of safety rather than an exact outline.
For a video, the tool shows the frame one second in. To check another moment, pause there and take a screenshot.
