Display modes and Picture in Picture
Updated
Display modes
The zoom button in the player cycles how video fills the screen:
- Fit — the whole frame is visible, with bars if the aspect ratio differs.
- Fill — the video fills the screen, cropping edges as needed.
- Safe — a middle ground that fills the screen while keeping more of the frame than Fill.
All three modes are available on iPhone, iPad, and Apple TV. On Mac, video always uses Fit, so there's no zoom button. On iPhone, the button appears in landscape.
