A reduced-motion preference can limit interface animation, automatic scrolling or other movement where the app supports it. It does not normally rewrite the motion inside a film or live programme. Treat menu accessibility settings and video picture-processing controls as separate parts of the viewing experience.
Identify the unwanted movement
A rotating hero banner, animated poster row and motion interpolation inside a film have different causes. Use an interface setting for the first group and television picture controls for the second. Disabling one should not be assumed to affect the other, especially when a browser and external player are involved.
Look for pause controls
An automatically moving carousel should offer a usable way to pause where implemented. Keyboard focus and pointer hover can also affect movement in some interfaces. Test the actual page rather than relying on a system preference being honoured by every third-party application. A stable poster grid can be easier to browse than a constantly shifting row.
Keep choices visible
On shared devices, explain when reduced motion or autoplay preferences are changed. A viewer should be able to browse without unexpected movement while still choosing a programme deliberately. If an app ignores the preference, report the specific animated element and version instead of describing the media stream itself as faulty.
