| Luminance Shift/Flicker | |
| Display Text | Luminance Shift/Flicker |
| Description | "Luminance Shift/ Flicker" refers to a change/multiple changes in the brightness levels within a shot/scene. |
| Impact | Luminance shift/flicker can distract from the creative on-screen action, and in severe instances, potentially obscure plot pertinent elements. |
| Severity Assessment Guidance | |
| FYI | Source of luminance shifting can reasonably be attributed to an on screen element or is understood based on contextual cues (e.g. strobe lights in a nightclub or character turns away from a practical light source). |
| Issue | Changes in luminance are not reasonably discernible as creative and distract from on screen action. |
| Blocker | N/A |
| Solutions | |
| How to Prevent | Review for luminance consistency across shots. Apply luminance changes uniformly within each shot and across similar shots whenever possible to minimize abrupt shifts. |
| How to Fix |
Confirm if creative intent or best possible. Otherwise, affected shots must be regraded to maintain consistent brightness and minimize unnecessary shifting mid-shot. If abrupt luminance changes are occurring within a DolbyVision trim pass, confirm that your metadata cut points are lining up with your actual cut points. Re-export metadata with inconsistencies corrected. |
