摘要： A system and a method are for comparing video content with different attributes. The method includes determining for a first rendition of video content a first value for each of a plurality of video attributes of the first rendition of the video content; determining for a second rendition of the video content a second value for each of the video attributes of the second rendition of the video content, the video attributes of the first and second renditions including parameters associated with a playout of the video content; identifying a first one of the video attributes for which the first value is different from the second value; determining scaling or adjustment parameters for matching or normalizing the first and second values of the first video attribute; generating a transformed rendition of at least the first rendition having an adjusted value for the first video attribute so that the video attributes of a transformed first rendition match the video attributes of the second rendition or a transformed second rendition; and performing a comparative analysis between the transformed first rendition and the second rendition or the transformed second rendition to identify frames in which a comparative performance metric indicates an error or issue in the first rendition or the second rendition.
