ffmpeg - rotate mov video 90° clockwise?

[varekai]

I couldn't find an ffmpeg thread so I'll post my question here.
If there is a thread for ffmpeg I'll edit this post and move it there.
Here goes...
I have some 1280x720 iPhone 6 mov videos I'm trying the rotate 90° clockwise.
iPhone is not getting the format rotation right, you'll never know how it will end up!
I hate Quicktime, used to have it installed but refuse to install it again.

The ffmpeg settings below works alright but the bitrate gets very low and the aspect ratio is way off.
I would like to keep the quality as close as possible.
This is what works for getting the rotation right from 1280x720 to 720x1280:

ffmpeg -i input.mov -c:a copy output.mov

What do I need to add for keeping the rest of the input file intact? Is it possible to do with ffmpeg?
I've searched high and low and tested more than a dozen different rotation ffmpeg settings and they all come out wrong.
Except for the one above but it doesn't get it all right unfortunally.
Any help would be highly appreciated!

Thanks...

use -vf transpose=1

[sneaker_ger]

If you need to use the transpose filter (because your player doesn't obey simple rotation flags) then ffmpeg will completely re-encode the video. It doesn't really try to make it exactly as the source. If you want higher quality you need to lower -crf (or increase -b:v ).

Thanks for replying! Appreciate that!

Let me try to explain and I'm sorry for not giving the right conditions...

The input.mov is right in the sense it's showing the person in the movie upright but streched like "fat and short".
You guys got me thinking... perhaps I'm not having the right approach?
Maybe it's only the aspect ratio 1280x720 that is the culprit?

I have tried this before and it doesn't work.
ffmpeg -i input.mov -vf transpose=1 output.mov
It shows the person right "slim and tall" but tilted 90° clockwise, and size is about 7.8MB and bitrate a lot lower, 2455kb/s.

This works but not correct all the way? It's almost exactly the same 32.9mb size and same bitrate 10.7mb/s.
ffmpeg -i input.mov -aspect 720:1280 -c copy output.mov
It plays fine with right "slim and tall" 720:1280 AR but in preview it's still shows 1280x720 and is tilted 90° clockwise.
Also aspect ratio looks strange 0.562?

I have some 1280x720 iPhone 6 mov videos I'm trying the rotate 90° clockwise.
I have tried this before and it doesn't work.
ffmpeg -i input.mov -vf transpose=1 output.mov
It shows the person right "slim and tall" but tilted 90° clockwise
So do you or do you not want to rotate the picture? :confused:
What is (full text) MediaInfo of input file?


0.562 ~= 9/16, i.e. the inverse of the common 16/9. So maybe it's players fault for wrongfully applying AR before/after rotation. Or file is wrong. Either way it could be fixed by re-encoding to non-rotated file with 1:1 sar. Maybe you can upload the actual sample?

[varekai]

Sorry, but I had the wrong approach, I apologize.
It looks like that a aspect ratio correction is what I need.
MPC-HC plays input.mov correct "slim and tall" but tilted 90° counter clockwise.
MPC-HC plays output.mov upright like PotPlayer but "fat and short" tilted 90° counter clockwise.
I'm so confused right now! :confused::confused::confused:

Not sure what's the issue, but I have used this in the past

ffmpeg -i wrong.mp4 -c copy -metadata:s:v:0 rotate=0 right.mp4

where rotate is an absolute value.

Thanks for replying!
I believe the issue is about wrong aspect ratio.

Haha... That's exactly how the input.mov looks like, but without the clowns & beers & basketball... :D

[sneaker_ger]

Can you try
ffmpeg -i input.mov -vf null -c:a copy output.mov
?

[varekai]

Thanks!
This works OK! But video is unfortunately compressed to a lower bitrate; 2452kb/s.

[sneaker_ger]

Like said: you need lower -crf for higher quality.

ffmpeg -i input.mov -vf null -c:v libx264 -crf 18 -c:a copy output.mov

Ahh, I forgot...
I get this message:
Past duration 0.649986 too large 17152kB time=00:00:25.65 bitrate=5476.2kbits/s speed=1.65x
Doesn' look like an error though.
Thanks all for sorting things out for me in my efforts to use ffmpeg.
Learned at lot, more to learn, lots of fun! :D
