Xiaomi Mi 8 selfie vertical video upload resolution problem-to youtube. Orientation problem.

I didn't really try to recording video with my smartphone before. And especially use with selfie camera.
But nowadays I'm thinking about recording video because it seems to me that not many people (in my country) trying to read article from the internet--especially like my blog--because I don't lure people.


Anyway, after record video with front camera, I think video quality wasn't bad. Actually it was quite nicer than I expected.


So I tried to uploaded to youtube but video resolution was reduced to 480p.
I think it has some problem with vertical video resolution, Mi 8 recorded vertical mode in slight different(or proper) way--like photo with portrait setting. 


but as you can see, video quality isn't good because it's jut 480p video.
So I googled about it and it looks like nowadays youtube will recognise 1080p video very well if uploaded video file is 1080p.

I uploaded it again(and again) with different filename--because if it's same filename, it became duplicate video. But it was same 480p video.

And I realised that video is vertical video so I googled about it--with keyword like this - 'youtube vertical video quality'.
Last year, youtube properly work with vertical video--without black bars.



Xiaomi Mi 8 portrait video is like photo's--based on orientation info.

And it seems to me that if it's 1080p vertical video, youtube properly work. So why my video wasn't uploaded it as 1080p video.
So it must be problem with my video file.

And I remembering some playback issue with PotPlayer which is video player in Windows 10. Last time, it did rotate whole screen to play this vertical--portrait video.


Screenshot of vertical-portrait video's media information in VLC player.

As you can see in the photo.
Video resolution is 1920x1080. If it's portrait video, it should be 1080x1920, right?
So how this can play as portrait mode?

You can see next highlight item in the photo. Orientation is 'Bottom right'. I don't' know what it refer to the 'Bottom right' is but I know this orientation thing when I was trying to editing the photos.
Sometime, this orientation things make mess when I am trying to editing it or uploading it to photo sharing websites.


So I had to use open source software Shotcut for just export to mp4 file. After that, I can upload to 1080p which you can see from below:





I'm not quite sure where should I report this issue. Xiaomi Mi 8's video shouldn't record like that--don't use orientation setting or something. Or youtube should properly recognise orientation setting in video files.

Or I didn't use properly like need some setting in portrait video mode (there has no other settings though) or something.
