Rotate videos from script and Mux video+ audio!!

[Cauptain]

Hi all, how do u do guys?

Once again, need a help.

I have 91 videos that look like this.



I need you to stay that way.



I can do this in FFMPEG one at a time, but I don't know how to create a script to make all inside the folder.

All my videos are separated into files (video + audio) and I don't know how to mux to mp4.

They look like this: video test1.mp4 + video test1.aac.

Is there a script to mix all 91 videos after rotate all?

resume:

Script 1: Rotate all video files from folder
Script 2: Mux to MP4 all rotated videos with aac files

Thanks,


Claudio

Feel free to elaborate on this batch job

if not exist rotated md rotated
for %%g in (*.mp4) do (
ffmpeg -i "%%g" -i "%%~ng.aac" -c:v libx264 -vf "transpose=1" -c:a copy "rotated\%%~ng_rotated.mp4"
)

as a side note:
In case the player support it, one could use:

ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=90 output.mp4

to rotate the clip without reencoding and loosing quality, if I read https://www.ffmpeg.org/ffmpeg-all.html#rotate correctly.

It appears MPC-HC is used as player.

My version - rather old 1.7.10 - doesn't support the rotation flag (metadata).

WOW!! Too easy using this method Selur. Really easy.

Working in all players on my PC.
