You can now invite people to work on a video without leaving the editor. Open Share and choose People.
Invite from the editor
The People pane shows who already has access and lets you invite more by email or GitHub username, as Editor, Commenter, or Viewer. Copy their invite link from the list, or remove someone at any time.
Videos that are not in a project
Collaborators join a project, so they see its videos and media. If the video you are sharing is not in a project yet, the pane offers Create a project for this video, which makes a project named after it and moves it in, or Add to an existing project. The invite form appears right after.
This also fixes the red Collab unavailable label and the "Not found" panel that showed for videos outside a project.
Shorter tabs
The Share tabs are now Video, People, Link, Embed, and Article, so they fit on a phone.
