Changing PAR of MP4 video

[Mephesto]

I always used to do MP4Box.exe -par 1=16:9 "video.mp4" which worked fine in the past but not anymore.

It screwed up the resolution in the header so MediaInfo now reports 720x4294964692 instead of 720x400. I had to delete and re-encode.

What's the new trendy way to do this since MP4Box doesn't work anymore?

[aedipuss]

delete it and use the backup copy of the video you made before messing with it?

or toss it and say oh well, i'll remember to make a backup next time

[Baldrick]

Try remux with something else? Like ffmpeg or avidemux(under video and audio choose copy).

How many threads is this guy going to make about the same exact topic?

With MP4Box you set the PAR, not the DAR.
To set a 720x480 video to 16:9, you need a PAR of (480/720)*(16/9) = 32:27 ≈ 1.185
For other frame sizes you have to tweak the numbers.

GaePussy sealed the fate of this topic with his usual faggotry, so a new one commenced which by the way is not the same as this one. I've re-encoded so the header has been restored but I still need to shift the PAR which MP4Box can't do anymore, hence a new thread.

This one may be closed.

Edit: Wow I see the other one has been closed instead, nice.

I know that. Never did I mention DAR anywhere.

WOW, that has to be a reason for deleting your whole thread!!
I would say if anyone sealed the fate of this thread it was you!!

Evidently you don't....
Does your dumbass mean like this in your very first post ?

All I was trying to do was change the display aspect ratio. How do I fix this?

Well I did try starting a new thread, but since Baldrick locked the wrong one, this'll simply have to be the substitute. Got a problem with me editting the thread to reflect the actual problem? Take a chill pill and quit trolling, bro.

OKey. Back to the topic now.


What mp4box version are you using? Maybe try mp4box 0.5.1 dev from http://gpac.wp.mines-telecom.fr/downloads/gpac-nightly-builds/

Thanks Baldrick, that new MP4Box worked. I'm using r2735, but I'm switching over to that GPAC one now.
