TelemetryTV's playlist editor makes it easy for you to create a playlist for a vertically oriented screen.
Here's how to set it up step by step:
From the Playlist section, go to the playlist you would like to create for a vertical screen (or create a new playlist).
Click on the "Configuration" tab at the top of the page.
Under "Aspect Ratio", click the drop-down and select "Portrait"
Click the "Playlists" tab to go back to the editor. Your playlist is now in portrait mode and you can start creating!
💡 Pro tip: You can also use the "Custom" aspect ratio option to create a playlist layout of any aspect ratio. This is especially useful for video walls. Click here to learn more.
