+      Keying is the process of compositing MLT output over a live SDI input.
+      The alpha channel of the MLT video controls the transparent areas, and
+      the keyer supports alpha-blending. You can not control the compositing
+      rectangle. Rather, the entire MLT output overlays the entire video
+      input. Therefore, you must use MLT's compositing services to control
+      the size and position. The value 1 enables the internal keyer, the
+      value 2 enables the external keyer, and the value 0 disables it.
