Emby automatically rotates uploaded video

[Nitro_Zeus 11]

I have some videos recorded on my phone while standing vertically. And when I play the video on Emby, it's horizontal. So the video gets turned on its side, and I think it's because it was shot on an iPhone while held vertically. What can I do to fix this so Emby does not change my video

I tried playing the video on a computer and another phone. And it's tilted to the side on both devices.

Hi, the video probably contains rotation information that tells us that it should be rotated when played.
