Acknowledging that HDR monitoring for every display on-set for the entire length of a production is prohibitively expensive for most productions, Netflix proposes three alternatives:
CAMERA TESTS (E.G. HAIR & MAKEUP TESTS)
Camera tests for hair and makeup are typically the first time images are evaluated and sent through the entire production pipeline. Some productions choose to monitor in HDR during the test shoot day or at a picture finishing facility immediately afterward. Then, they continue with on-set SDR monitoring during production. This is usually the lowest cost approach to HDR monitoring.
LIMITED RUN HDR MONITORING ON-SET
In a Limited Run workflow, the HDR reference monitor is only on-set for certain weeks of the production schedule (ideally the first two weeks of production). This helps key stakeholders gain a better understanding of how the final image will be displayed in HDR. Once these stakeholders are comfortable with the format, they can stop using the HDR display and continue the remainder of the production using SDR monitors.
ONE HDR MONITOR ON-SET
Rather than make every monitor on-set HDR, this approach uses a single HDR reference monitor for the full run of production. Regular access to said monitor can help key stakeholders continually guide how their creative decisions will be manifested in HDR. The other monitors on-set, such as those in the “video village”, receive an SDR signal.
