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.

i found out that when i play the video via Emby App it's displayed correctly. but when i use the web link it rotates to the side. 

What do you need from me to investigate the issue?

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

With Copilot, I looked through my Embyserver.txt log and found this;

-noautorotate  
-metadata:s:v:0 rotate=-90

This means:

• Emby ignores the original iPhone rotation metadata (because -noautorotate forces ffmpeg not to respect it).

• Emby then adds its own rotation = -90°, which flips the video sideways.

• This only happens in the web player, because it uses HLS transcoding.

• The Emby app uses direct play, where rotation metadata is respected → therefore the video looks correct in the app.

I downloaded ffmpeg on Windows https://www.gyan.dev/ffmpeg/builds/?utm_source=copilot.com 

And ran this command in CMD to change the files from .MOV to .MP4 and h.264 with fixed settings. 

for %i in ("C:\Users\USERNAME\Desktop\*.MOV") do ffmpeg.exe -i "%i" -c:v libx264 -preset fast -crf 18 -c:a aac -movflags +faststart "C:\Users\USERNAME\Desktop\%~ni_fixed.mp4"

This issue has been solved
