Customize your video library to have it match your site or just make it stand out. To begin, click Settings > Branding.
Choose the On-Demand option. As you make changes, save them at the bottom, then preview those changes using the 'Your page' option in the top left.
Once you land on 'Your page,' click On-Demand Videos and Courses.
You'll see all customizations here. Pro tip: leave this tab open and refresh it as you make changes in the customization page.
