iOS app uploading videos with reduced size?

I’m having an issue with the nextcloud iOS app, I turned on auto upload and files started going up as expected - however - images are being converted to .jpg and videos are uploading at only 720p instead of 4k which the original is. I have been through the settings on the web access and the app and there is no setting that indicates it reduces the video size so significantly. I have ā€˜Most Compatible’ turned off.

Can anyone point me in the right direction to upload originals or is this a bug in the app?
