No worries at all! People use many different methods to share shots here. I tend to use vimeo to share work-in-progress, and then when it’s done vimeo allows you to make the clip downloadable, which puts a download button next to the player (and if you click “Original” when downloading it be the exact file uploaded, so in my case prores files). I also use google drive, which seems to be more and more popular here. It’s nice because, like vimeo, allows you to share file and uses youtube’s player if you don’t want to download!
Edit: Agree with liambrazier about password-protection, that’s one of the things I like about vimeo!
