Signal Range
Full range vs Video range
Overview
When integrating OmniScope with OpenFX, users can select between two signal modes: Full Range and Video Range. This choice affects how the signal is transmitted and monitored, focusing on the range and integrity of the signal.
Choosing a Signal Mode
Video Range
To ensure accurate monitoring of signal levels within standard broadcasting limits (0-100 IRE), Video Range is recommended. This mode configures the OpenFX plugin to transmit deep blacks and super whites, allowing you to detect whether the signal stays within the 0-100 IRE range without clipping.
Use Case: Choose Video Range when verifying that the signal does not exceed broadcasting levels of 0-100 IRE. This mode is suitable for outputs where maintaining signal integrity within predefined limits is crucial.
Full Range
For scenarios where digital production is the focus and legal range checking is not a concern, Full Range should be selected. This mode does not compress the 0-100 IRE range into 64-960, thereby avoiding the typical broadcast range compression. The signal is clipped to 0-1023 in a 10-bit environment, which means details outside this range cannot be detected post-clipping; however, this approach preserves the quality of the original signal.
Use Case: Utilize Full Range when working in digital environments where you are not confined by standard broadcast signal limits. This mode is ideal for projects that benefit from higher signal quality without the need for compression into a narrower range.
Summary
The selection of the correct signal mode in OpenFX is crucial for achieving optimal output quality and fidelity. Choose Video Range for rigorous adherence to broadcast standards or Full Range for higher quality in digital production settings that do not require legal range monitoring.
