Comment (by idest):

 > Do you think otherwise? Why?
 I do, the reason is this: if you change aspect ratio with a command like
 this:

 {{{
 ffmpeg -i in.mp4 -aspect 11:3 -vcodec copy out.mp4
 }}}

 , and then analyze the resulting video with ffprobe:

 {{{
 ffprobe -show_format -show_streams out.mp4
 }}}
 , you'll notice that the "sample_aspect_ratio" and "display_aspect_ratio"
 values, which are related to aspect ratio, are shown in the [STREAM]
 (video stream metadata) section, not in the [FORMAT] (container level)
 one.
