"The image area on the reference grid is defined by its upper left hand reference grid point at location (XOsiz, YOsiz), and its lower right hand reference grid point at location (Xsiz – 1, Ysiz – 1)" (15444-1, 8.2) AFAIK setting the MXF aspect ratio item to the ratio of the image pixel dimensions only works if (a) the pixel aspect ratio is 1 and (b) the video is not interlaced -- see 6.2.1.2 and Annex H at https://pub.smpte.org/doc/st2067-21/20221124-pub/. > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
