1. A computer memory that is not a transitory signal and that comprises instructions executable by at least one processor to:

  • access first and second brightness metadata pertaining to respective s and second contents;

    responsive to receiving a command to change presentation from the first content to the second content, establish a composite brightness using the first and second metadata;

    present at least one of the contents using the composite brightness at a start time of a transition period;

    during the transition period, present video using a changing brightness that starts at the composite brightness at the start time of the transition period and ends at the second brightness at an end time of the transition period; and

    subsequent to the end time of the transition period, present the second content using the second metadata and not using the first metadata, wherein the first and second brightness metadata include respective first and second peak and average brightness values, and the composite brightness includes a composite peak brightness value derived from the first and second peak brightness values.
