Make it look native
- With the Auto background, Fit uses a soft, darkened blur of your own recording behind it, the look most vertical videos use.
- Content sits a little above centre so captions fit underneath.
- Use the camera's Side by side layout: in vertical video the screen sits above your face.
- Keep text callouts short; vertical screens are narrow.
