I use Wistia which is excellent. https://wistia.com/
Best bits for me are
– Project organisation (top level project name – make your own subsections – all flexible)
– multiple client login with tracking of sessions (did they watch it? All of it? .. etc)
– url links to access videos for clients who can’t handle login/password (!)
– Commenting made easy (auto adds the timecode where they want to make a comment “remove this shot” etc)
– Viewable online or downloadable
It’s a pay-for service, but has a free trial.
Otherwise Vimeo gets the free thumbs up.
