Zebra

Zebra is a way to indicate overexposure. When the brightness (IRE) of a part of the image exceeds a set threshold, that portion of the image will display as a black-and-white striped pattern. Using zebra, cinematographers can quickly adjust the overexposed areas of the image, ensuring that the image is properly exposed.

Default: [Off]

The default threshold for zebra is set at [95%], but it can be adjusted between [12%] and [99%]. For example, if the zebra threshold is set to [90%], zebra will appear on any part of the image where the brightness exceeds 90%.

Default: [95%]

Notice Similar to the waveform, some camera allow adjusting the Look (LUT) of the SDI output. When the SDI output is LOG and the brightness clipping occurs at 80%, zebra stripes will not appear if the threshold is set above [90%]. In this case, it’s important to monitor the waveform for clipping to prevent overexposure in the image.
Notice It is not recommended to set the zebra stripe threshold too low, as this will cause the zebra stripes to fill most of the image, affecting the ability to judge exposure and other factors such as composition.
