Calidad de audio Deberias mejorar la calidad del audio, ya que si lo comparo con Youtube, el audio queda un poco distorsionado, y si es audio MP3, a veces suena como M4A, tambien la calidad del audio pasa de 160K a 128K

HTML5 Video Feature It'll be nice if most of the videos are HTML5 supportive like YouTube did, like switch Flash to HTML5 in your account options if you want.

More email domains for registration I think it would be a good idea for VidLii to allow more email domains during the registration process. Currently they only support gmail and a few others. When I registered, I wanted to use my secure email address at tutanota.com, but unfortunately I had to use my old gmail address that I do not check as often in order to complete registration. Please consider expanding the list of acceptable email domains!

How about giving the users an option To self-host Vidlii similar to platforms like Peertube and LBRY so that just in the case that something bad might happen to the website, and you're unable to host it people can just create instances of Vidlii and bring it back to life.

Custom Thumbnails Really loving this site! Would be awesome if we had the option to choose custom thumbnails rather than just having one default thumbnail when uploading a video.
