Hey,

So I've edited my own videos on an editing app but cannot find a URL to add the video to my profile. Is there a specific website where I can upload my own video edit and get a link from there to add it to my profile?

Thanks, Sorry I'm asking a lot :D 

Well, YouTube is the safest choice for you and anyone who will check your video. Also mdl supports embedding for youtube videos.
