Media upload limit

[Numbered]

I'm sorry for that stupid question. We want to upload 6 MB video in our media for using as a background for landing page. But the media only allow 5MB max

 

Can somebody say where I can increase this limit? My nginx client_max_body_size set to 50M, php values post_max_size and upload_max_filesize set to 51M both. The admin group settings have no any file limits. The public area shows 50MB limit correctly.

Thank you
