Luminance - Loss of Detail in Highlights

Description:

Loss of Detail in Highlights is the adverse effect in which the images or section of image's highlights exceed the maximum reproducible video level, and appear to solidify in value. 

Impact:

Image quality is degraded by the loss of detail, negatively impacting the customer experience and technical soundness of program, although sometimes creative intent.

Severity Structure:

FYI

N/A

Issue

Substantial portions of the image have minimal detail due to the image luminance levels clipping at peak.

How to Prevent:                          

Set base black levels at 100 IRE.

Verify that the timing is consistent across multiple shots.

Solution:

Please review and verify if creative intent, otherwise may be a conformance issue, Full/Legal Range conversion issue, or the color timing did not render in the sequence to derive the master.
