Dim flashing video shared in a meeting or webinar
Participants with photosensitivity can can be unprepared for flashing and strobing effects in a video shared by others in a meeting or webinar. When you enable video dimming in your personal settings, the Zoom app can recognize these effects and automatically dim the incoming video, reducing the impact of those video effects on the viewer.
Enabling this setting has no effect on others’ view of the shared video, and others are unaware if this is enabled by anyone else in the meeting or webinar.

What to expect when flashing images or visual patterns are detected
When starting to view shared content, the shared video will be unaltered and shown to you with 0% opacity.
When flashing images or visual patterns, such as stripes, are detected in the shared video you are receiving, the entire shared screen will dim to 75% and remain dimmed until 4 seconds of safe, non-flashing video content is detected.
