  1. I've got the following .mp4 file :

    MediaInfo screenshot:


    and it has wrong aspect ratio, as you may see, 3.115 : 1
    So I'd like to permanently change it to 2.35 : 1
    (that's how I make it viewed correctly in mpc-hc: Video>Video frame>Override Aspect Ratio>235:100)
    without re-encoding it.

    I've read this post mentioning mp4box.
    I've tried following it but without success.

    Please help.

    1280/544 is 2.35 pixel aspect ratio. So try change the par value to 1:1

    2.35 = 1280/ 544 * 1/1

    Code:
    mp4box -add inputfile.mp4#1:par=1:1 -add inputfile.mp4#2 output.mp4
