My description of being displayed in a small rectangle was trying to say this. I'm struggling to describe the problem in the correct terminology so please bear with me. Here is ffprobe info: Original .ts file recorded by my Humax: Stream #0:0[0x931]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv), 704x576 [SAR 16:11 DAR 16:9], max. 15000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc 1280x720 .mp4 exported from OpenShot: Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720, 14925 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default) The OpenShot export parameters used DAR 16:9 and Pixel Ratio (which I assume is the same as SAR) of 64:45, although it doesn't set the DAR or SAR in the file metadata (I did this subsequently with ffnpeg). I realise that the original .ts video is actually letterboxed, although the vertical side bars are pretty narrow. I've always assumed that letterboxing referred to the top and bottom horizontal bars and was just a side effect of playing a widescreen movie in a 16:9 or 4:3 display. I also did wonder how the how this original movie played with the correct (at least correct looking) AR when the DAR is set to 16:9 - the measured AR on my computer screen is more like 24:10. So it occurred to me - has this video been letterboxed to play in an AR of 16:9 when its real AR is greater? -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
