You can add videos to your Playlist video player from the Video tab in your dashboard. Just check the 'add to playlist' checkbox when you upload or edit a video.
If you want to remove a video from your playlist, click ‘Edit’ on that specific video, uncheck that box, and click 'Save'.
You can now add or remove up to 50 videos at once to your playlist with our new beta video interface. See more information here: How can I bulk upload and bulk edit videos?
