HDR production: Five concepts, 10 principles

Tuesday, 20 June 2017

It is likely that the next major versions of common NLEs will support HDR. As editors we will be asked about the right HDR workflow. For now it is a matter of picking a standard, following some guidelines and maintaining metadata.

HDR sounds complex, and at a technical level it is. Abstractly, however, it involves just five simple concepts.

First, to acquire the expanded brightness and color palette needed for HDR display, you have to capture and maintain your video in 10-bit or higher formats. Second, you’ll need to color grade your video to fully use the expanded palette. Third, you’ll have to choose and support one or more HDR technologies to reach the broadest number of viewers. Fourth, for several of these technologies, you’ll need to manage color and other metadata through the production workflow to optimize display on your endpoints. Finally, although you’ll be using the same codecs and adaptive bitrate (ABR) formats as before, you’ll have to change a few encoding settings to ensure compatibility with your selected HDR TVs and other devices.
