Details
- Description
- "Luminance shift" refers to a change in luminance within a shot or scene, where no on-screen motivation supports the change.
Luminance shifts impact the technical and content quality of the asset. Customer experience will be negatively affected if the luminance of the piece shifts so greatly that it is either too bright or too dark to gather plot-pertinent information.
This may be creative intent, although context clues should point to this.
Any video created from this asset will contain luminance shifts. - Definition
- Used in Checks, the system shall review the content for luminance shifts within the same shot. Optionally, the system may report timecodes of where luminance shifts occur.
Used in reports, the system shall report the timecodes of where luminance shifts occur. - References
