Statistics plugin for Davinci Resolve

The Statistics Plugin for Davinci Resolve* is delivering frame statistic values, respecting different delivery standards such as BT.709 SDR or BT.2020 HDR.

SDR values can be influenced by setting a power function (gamma) and defining a peak brightness level.

It creates an information window (overlay or GUI) for the following values:

Average Picture Level

Average Red

Average Green

Average Blue

Max Level

Min Level

 

Explanation for Options

Calculate Mode

normalize (legal range): When this option is activated, the Statistics plugin for Davinci Resolve performs a normalization of legal range values. In other words, values of the legal range of video are expanded (0…1). This option is useful for situations where the Project settings require full range but you want to analyze what’s going on in the legal range of the signal.

If switching to legal range causes values above maximum (e.g. above 100% or 10000 nit), then you either have a situation where you should not use the normalize button or you’re exceeding the legal range, which might lead to clipping your delivery format.

EOTF: The EOTF selector currently supports SDR (gamma value), HDR (PQ/ST.2084) and Picture Level (%).
For SDR, you have the choice of choosing a gamma value like 2.2 or 2.4 (default) and a peak brightness of your mastering display.

 

 

The calculations are similar to CEA 861-3 while MaxFALL and MaxCLL correspond to Average Picture Level and Max Level in the plugin.

*Note: This Plugin is made for Davinci Resolve 14 running on a Windows System with a CUDA-enabled (NVIDIA) GPU. We intend to deliver a Mac and a Linux-Version with OpenCL support after we can see that there’s reasonable commercial interest in this plug-in. Please don’t purchase this plug-in if you don’t have a Windows PC with a NVIDIA graphics card and Davinci Resolve 14 or later installed.
