Hi everyone, I am new here and I apologize if I posted my question in a wrong section, but this is the best that I could find. I have a small adult paysite and I am planing to open mobile version on subdomain. In my members area all videos are HD in MP4 format, video file sizes are small (20MB-800MB), do I need to convert in some another format or is MP4 good to be played on all mobile phones and devices? Please advice me, I don't have any experience with the mobile phones. Thank you!
