@Andrew In my opinion the BT 601 PAL tag (mediainfo) is wrong, in fact the file is described as YUV, NTSC 8-bit, and these are data taken directly from the file, while the primaries is a metadata that can also be wrong. I tried ffprobe and it confirms smtpe170m i.e. NTSC. @Phyllis Test with ffprobe. Mediainfo is not 100% accurate!
