iOS 16.4 Beta: How to automatically dim videos when flash is detected

In iOS 16.4 and iPad 16.4, currently in beta, Apple has added an accessibility option to darken videos when a flash or strobe effect is detected. Here's how to enable the feature on your device.

When watching videos on your iPhone or iPad, the content may sometimes include a rapid flash or strobe effect. In this case, a key issue is user security.

Some people with photosensitive epilepsy may be affected by strobing lights, which may trigger seizures. This effect can also produce undesirable sensations, such as visual impairment, in the general population.

With this in mind, Apple has added a new option to its accessibility feature set to automatically reduce the brightness of a video if it includes trigger light effects.

The following steps show you how to enable this feature. Note that you must have iOS 16.4 (currently in beta) installed on your device to see this option. You can check if your device is up to date by going to Settings -> General -> Software Update.

1. Open the "Settings" app.
2. Scroll down the menu and click Accessibility.
3. Under the Vision section, tap Motion.
4. Switch the switch next to Dim Flashing Lights to the green ON position.

Everything here belongs to it. The next time you play a video and iOS detects a lighting effect, the screen will automatically dim to reduce the chance of a negative reaction.
