( changing mkv display doesn't change it )
So, I have this file with the following media info:
Code: Select all
Width : 670 pixels
Height : 574 pixels
Display aspect ratio : 5:3
Original display aspect ratio : 5:3
edit*
These are PAL res which are/are not upscaled.

There are two places in an MKV file that the aspect ratio can be found - one of the headers (which you're trying to edit) and in the video stream itself. They're supposed to match.
Which one is used depends on your player - some read the stream, others look at the header. Which is why they should match....

You're editing the header only, correct? Because MakeMKV isn't going to change what's in the video stream, and I don't think mkvtoolnix does that, either.
However, if I edit the headers of something I've encoded, ...
If you're
re-encoding the video, then it is important that the encoding program gets the correct aspect ratio. I've found that handbrake gets the correct aspect ratio even when the header value is screwed up, because it reads the video stream. It then sets the header on the output file to match what it encoded.
