megapixel HELIOS - Mastering Content for Display Luminance

HELIOS LED Processing Platform - USER GUIDE
100
Content should always be intentionally mastered at a MaxL matching the nal display's nit level. In the real world, however, it is
quite common for content to be delivered at a default of 1000L. Below are a series of images showing how correct vs incorrect
metadata can greatly increase or decrease detail and delity. Note the detail of the buildings outside the window are lost. This is
due to a Display MaxL of 100 with Content MaxL defaulting to 100L due to a lack of metadata in the video signal. The actual
content was mastered for 1000L, so all levels above 100L will lose detail.

In the second image, the Content MaxL has been overridden to 1000 nits to match how the actual content le was
mastered. Notice the signicant increase in detail in the buildings outside the window.
