- Description
- Negative Stain is an artifact that appears as the inverse of an expected on screen appearance.
Similar to a pixel error, the appearance is typically unintended and can act as a distraction pulling attention away from the focus of the programme. - Definition
- Used in Checks, the system shall review content for negative stains. Optionally the system may report timecodes at which the error exists and the position in the frame of the error.
Used in Reports, the system reports timecodes at which error exists and the position in the frame of the error. - References
