Make your own YouTube uploader form and let anyone upload videos of any size to your YouTube channel. The uploader can send videos even anonymously without a Google account.
It is easy to upload videos to your own YouTube channel but there’s one limitation. Only the owner of the channel can upload videos to their YouTube account and they cannot delegate the task to someone else in the team.
Google Drive has the concept of shared folders. A folder can have multiple collaborators and anyone can upload files to that folder. Wouldn’t it be useful if such a feature were available for YouTube channels as well? You maintain a single YouTube account and multiple people can upload videos to your common account without the owner having to share their Google account credentials with anyone.
