Ah, sorry.
The 3 videos I had started from to make the BD Render were not
1440x1080, this size was just set in the BD Render window. The three
project's files were:

sad_woman.mxf (a DNxHR render of mine from a h264/mp4):
$ ffprobe -hide_banner sad_woman.mxf
[dnxhd @ 0x60dc04c06140] frame size changed: 1920x1088 -> 1920x1080
Input #0, mxf, from 'sad_woman.mxf':

PS: I am also curious where the ".m2t.ts" came from, but I just don't
remember the time when it appeared.
