This is the file function handle this video duration generate this format %H:%I:%S

JoomlaFolder/administrator/components/com_easysocial/includes/video/video.php

But it will not convert the hour to minute automatically, it needs to customize the code in order to achieve this.

However, I am really sorry but unfortunately this is beyond the scope of our support and we would not be able to assist you on this.

Thanks for understanding.
