This video was uploaded as a HDR (High Dynamic Range) video. As a result, those viewing this video on a SDR (Standard Dynamic Range) display may experience issues with color accuracy or brightness (i.e. darker than expected). This depends on how good (or bad) YouTube tonemaps the HDR video to SDR. From the Ultra HD Blu-ray release of "South Park: Bigger, Longer & Uncut" (1999). This is seen at the end of the film. There is a short scene that plays after the Paramount logo that I've cut out of this video.
