PQ Calc

PQ Calc offers a quick and easy way to convert values along the SMPTE ST 2084 (PQ) electro-optical transfer function (EOTF).

The app is bi-directional and will convert the luminance level (nit) to the digital level in Full, SMPTE, or SDI-Full range and vice versa.  Calculations are available in float, percent, 8bit, 10bit, 12bit, and 16bit.  

To use, enter a value in either the "Level" field or the "Nits" field and choose your range.  The application will then populate the other fields simultaneously-- it's that simple!
