Exporting MKV loses aspect ratio about lossless-cut HOT 2 CLOSED

BTW comparing input/output in MediaInfo, there are many more differences between input and output:

Unfortunately this issue is one of many related to lost metadata, and I don't know how to fix it. Most likely it's a bug in ffmpeg. I will add this issue to #1027 and I'll close this to keep issues down.

Export files and doesn't change aspect ratios and have the black bars removed.

FYI removing black bars will probably never be possible in losslesscut because it requires re-encoding.

As for the aspect ratio, I think similar to this issue #1336 - I think some metadata (e.g. aspect ratio) gets lost when exporting.

I opened the input file (Episode S05E02-03.mkv) in IINA and it looks like this:

seems VLC parses the file differently because it shows it wider:

if I export using losslesscut and open in VLC I can confirm I also see the 4/3 aspect ratio.
