Aspect ratio SAR and DAR missing in exported MP4 file container data
When encoding MP4 files from Media Encoder or Premiere Pro the exported file is missing the SAR and DAR values.
This can be easily check with ffprobe and this command:
ffprobe -v error -showformat -showstreams file.mp4
codeclongname=H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
As you can see above the encoded file shows N/A values instead of the expected SAR value 1:1 and DAR value 16:9.
I have of course tested with other source files and mp4 files from other vendors and they provide these values in the mp4 files they create.
Is this perhaps a bug or missing feature?
Hope for a resolution in the near future :-)
