MPC-BE Rotate - but how to make the change stick?

[vhwul62]

I have a few, very old, videos. I tried converting with VLC, but the results were a drama.
Went through the steps on https://www.howtogeek.com/14751/rotate-a-video-on-windows/
However, persons were 'blown up' as VLC did not keep the original 4:3 size
Also VLC went in some endless loop when converting, asking to overwrite the original. Had to 'kill' VLC.


I figured out that in MPC-BE with alt-1 one can change the orientation.
Results look okay. But I have not found a way to make this change 'stick', i.e. when I relaunch the file (.avi) it will still be sideways, it is not saved/converted.

Maybe it is not possible with MPC-BE?

I do not want to spend much time on it: it involves just 3-4 files. If it requires installing this and that whatever, I let it rest.

Thanks.

The avi container does not allow quick and easy rotation.
mp4 and mov can. If the codecs in your avi allow a simple remux to mp4 or mov, then you can also rotate the video without recoding it.
Post a mediainfo report (text mode) of your avi file here and we'll see.

And MPC-BE is not a video editor. It is a player.

Thanks for the replies and very sorry for the delay.

There were some 3-4 videos (.AVI) only and I just now discovered that one of them -was- already rotated and converted to mkv many years ago but was stored in another folder.
Frankly, I have no idea how I did this. Maybe I used TMPGenc Mastering Works for it.

I tried the VLC method again just now and it worked out fine this time.
It beats me why it did not work in the first time(s) ... Output then was resized to width of the player instead of keeping 4:3 size.
(Followed the same steps, but maybe I forgot to click on 'Save' at some point, I don't know)

Anyway, it is solved now.
Thanks again for replying.
