Collections contain several videos that are meant to be viewed together. This is how you would go about creating a playlist in Uscreen.
Before creating a collection, upload all the videos you want to add to the collection under the video section. Make sure you've set thumbnails and all the regular details you would normally set for a video too.
NOTE: If you don't want the videos within your collection to appear in the catalog as standalone videos, don't publish those specific videos. You'll still be able to add them to collections without them being published. That way you don't have to worry about videos being watched out of context or potentially confusing your users who want to access your collection and land on the standalone video first.
Navigate to Content > Collections and click Add New. Fill out the details of the collection and Save your changes.
Next scroll down to the Playlist card and add the videos that will be part of the collection.
Lastly, head to the Thumbnails card and give your collection a category in the Organize card, then Save your changes.
If you're ready for it to appear on your catalog, you can head to Publication and publish it. Once you have your collection published, the playlist can be displayed in two different layouts: sidebar or thumbnails. To learn more, check our help guide explaining how to set each layout.
