I need to concatenate several mp4 files that were taken with a cell phone,
where some of them are landscape and others portrait. By simply concatenate
them, the ones that are portrait end up rotated by 90 degrees in the final
output.
To solve this problem, I decided to rotate the portrait ones one by one
before concatenating them. However, when I concatenate landscape together
with rotated portrait, I get the following error messages:
How did you rotate them?
Did you remove the rotation metadata?
Were the rotated video's reencoded?
