1. A computer-implemented compositing method, comprising:

  • receiving, by a processor, first data from a first source having a first dynamic range and an associated first electro-optical transfer function (EOTF);

    receiving, by the processor, second data, from a second source different than the first source, having a second dynamic range that is lower than the first dynamic range and an associated second electro-optical transfer function;

    converting, by the processor, the first data to a converted first data having a third dynamic range and an associated third electro-optical transfer function that matches at least a segment of the second electro-optical transfer function;

    assembling, by the processor, a video frame from the converted first data and the second data, andrendering, by the processor, an output frame based on the assembled video frame.
