Current total image brightness would be a useful value if fed the output of Motion Heat Map as it would correspond to intensity of motion. Can this be determined in VDMX natively? People in the VDMX Facebook group are suggesting creating a Vuo plug-in is the best way to get this value but I’d welcome any additional advice.
I don’t think there is a good way to do this natively in VDMX, but we have discussed the idea of a plugin for stuff like this.
A few years ago I made this tutorial on using Max alongside VDMX and my example case was something similar to this, using the jit.3m object to compute the minimum, mean, and maximum brightness values of each incoming video frame,
