Re: [FFmpeg-user] DAR/SAR
Sorry, I just saw that you already ran an ffprobe. If you run ffprobe again and look for Stream #0:0, does yours report the DAR as 4:3? If so, perhaps you were looking at Stream #0:2 when you were seeing the DAR 17:25. If not, then perhaps there's something else going on with your build. If that's the case, let us know which version you're running (usually reported at the top of ffprobe/ffmpeg output) On Tue, Feb 28, 2023 at 5:34 PM Steve Zemlicka wrote: > if you run ffprobe [filename], you'll notice that it does indicate 4:3 for > stream#0:0 > Stream #0:0[0x1](eng): Video: h264 (High) (avc1 / 0x31637661), > yuv420p(progressive), 640x480, 792 kb/s, SAR 1:1 DAR 4:3, 23.98 fps, 23.98 > tbr, 23981 tbn (default) > > When dealing with aspect ratios, it's always good to do a ffprobe to > examine the details of how ffmpeg will interpret/recognize the files.

if you run ffprobe [filename], you'll notice that it does indicate 4:3 for stream#0:0 Stream #0:0[0x1](eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(progressive), 640x480, 792 kb/s, SAR 1:1 DAR 4:3, 23.98 fps, 23.98 tbr, 23981 tbn (default) When dealing with aspect ratios, it's always good to do a ffprobe to examine the details of how ffmpeg will interpret/recognize the files.

Re: [FFmpeg-user] Video stretched wide
It seems the issue must stem from the source having two SAR/DAR values as follows: Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, smpte170m, progressive), 720x480 [SAR 8:9 DAR 4:3], SAR 1:1 DAR 3:2, 29.97 fps, 29.97 tbr, 1k tbn (default) Adding "-aspect 4:3" to the ffmpeg command was sufficient to output a result consistent with the source.

[FFmpeg-user] MKV to MP4 subtitle issue
The question I have is similar to the following post: https://superuser.com/questions/932730/ffmpeg-mkv-to-mp4-conversion-loses-subtitles I am using ffmpeg version n5.1.2. I have an mkv that has two subtitle tracks. I am trying to convert it to mp4. mkvmerge -i input.mkv File 'input.mkv': container: Matroska Track ID 0: video (HEVC/H.265/MPEG-H) Track ID 1: audio (E-AC-3) Track ID 2: subtitles (HDMV PGS) Track ID 3: subtitles (HDMV PGS) Chapters: 10 entries I believe Track ID 2 is for foreign dialog only and is the one I would prefer to use. I also prefer to use hardsubs but would take hard or soft subs at this point. I've tried a number of approaches with little success. The closest I've gotten is to issue the subtitle=input.mkv option. ffmpeg -i input.mkv -c:v hecv_nvenc -crf 26 -preset fast -c:a aac -b:a 128k subtitles=input.mkv output.mp4 I expected this to burn the subs to the video but oddly enough, it seemed to make an mp4 with a subtitle track to toggle. Unfortunately the subtitles are just the chapter names and not the actual subtitles. I've also tried to manually select different subtitle tracks by using "subtitles=input.mkv:si=1" as per http://ffmpeg.org/ffmpeg-filters.html#subtitles. Unfortunately this results in an error: "Unable to find a suitable output format for 'subtitles=input.mkv:si1'" followed by: "subtitles=input.mkv:si=1: Invalid argument" I've also tried several other options including "-c:s copy" which didn't work due to the nature of the original subtitles (PGS) I suspect. Am I doing something wrong or missing something? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
