+ "luma" gets its name from how it uses a grayscale "map" file. As the luma
+ value varies over time, a threshold filter is applied to the map to
+ determine what parts of frame A vs. frame B to show. It reads PGM files up
+ to 16 bits! Alternatively, it can use the first frame from any producer that
+ outputs yuv, but it will be limited to the luma gamut of 220 values. This
+ performs field-based rendering unless the A frame property "progressive" or
+ "consumer_progressive" or the transition property "progressive" is set to 1.
+bugs: Assumes lower field first output.
