"Compositing Error" is any artifact or impairment induced by or related to poorly implemented VFX/CGI. Can encompass many different types of errors from color and matte shifts on a character/object to extraneous artifacts that are not creatively inherent to a scene.
Compositing Errors impact the Content Quality of the Asset. The member experience is negatively impacted by obvious or poor compositing which can take them out of a seamless viewing experience.
Significantly noticeable VFX inconsistencies including, but not necessarily limited to, distortion around characters/objects, characters/objects appearing slightly transparent and incomplete or overlapping mattes.
How to Prevent:
Review VFX elements at both reference levels as well as with black levels boosted to expose noticeable compositing.
Likely needs a return to VFX to correct potential improper rendering.
Adjust matte or element to be consistent within frame/ shot.
