With interest in adding high dynamic range (HDR) to feature and TV content running high, global standards body Society of Motion Picture and Television Engineers opened its annual Technical Conference & Exhibition on Monday with the release of a 50-page HDR study group report that it hopes will help standards bodies and stakeholders to find some commonality and sidestep a potential format war.
High dynamic range is a term used to describe a wider range between the whitest whites and blackest blacks in an image, and is viewed by many in Hollywood’s technical community as a feature that will create a more noticeable different to consumers, compared with resolution (Ultra HD or 4K) or high frame rates.
But with numerous companies and organizations using the term HDR in different ways, there’s concern that this could confuse consumers and possibly even start a format war.
The SMPTE report includes definitions, guidelines and other information. Importantly, it raises “red flags” by identifying key areas that require consensus, including brightness levels, compression and distribution, said SMPTE standards director Howard Lukk.
