How to find on Internet Archive

Because the film is public domain, early uploaders in the early 2000s used archaic codecs (DivX, RealMedia, Windows Media Video 9). Today, many of those files are unplayable. The Archive’s "derive" system attempts to re-encode these files into modern formats (H.264), but the process introduces artifacts. In one notable Red River file (Item ID: red_river_1948_vhs ), the famous climactic fistfight between Wayne and Clift is obscured by "macroblocking"—a digital glitch where the screen dissolves into a grid of green and purple squares because the original bitrate was too low to handle the rapid motion.
