I am trying to share a video that I made with a teacher's public playlist. How would I do that?
First, your teacher should add you as collaborator of the playlist. Then (from Collaborate on playlists - Youtube Help):
Contribute videos to a playlist
Once you’ve been invited to contribute to a playlist, you can add videos or remove videos that you added in the past.
- Use the link you got from the playlist owner to go the playlist page.
- Follow the on-screen instructions to confirm that you want to be a contributor. The playlist will be automatically saved.
To add videos from your computer or a mobile device, use one of these options:
- On the playlist page, select Add Video and paste in a video URL, choose a video from your uploads, or search for a video on YouTube.
- Go to a video you want to add and select the Add to menu from that video.
After you add a video, your name will appear next to the video in the playlist. All collaborators will get a notification when new videos are added to the playlist.
