1. A method comprising:
receiving a video source stream captured by a video handling device;
authoring a video segment of the received video source stream, the video segment having a first stream associated with a first electro-optical transfer function with at least one portion correctly authored for a lower quality display and at least one portion incorrectly authored relative to a first electro-optical transfer function for a lower quality display;
displaying a single frame of the video segment comprising the at least one portion correctly authored and the at least one portion incorrectly authored, wherein the at least one portion incorrectly authored produces undesired visual artifacts due to an inadequate luminosity or chromacity range;
embedding at least one indicator into the at least one portion incorrectly authored within a frame of the video segment, wherein the indicator notifies a viewer that the at least one portion incorrectly authored is not playing at its full bit depth in accordance with the video source stream; and
enhancing the first stream by adding a bit pattern of a second stream to produce an enhanced stream, wherein the enhanced stream is associated with a second electro-optical transfer function having a higher quality than the first electro-optical transfer function, wherein the second stream includes compensating data for correcting errors associated with the first stream.
