If you have a video hosted on a third party website, such as YouTube, you can embed it into your OLR listing.
Click the Share button on your YouTube video, then click embed. Below the embed code click "use old embed code." This can be copied and pasted into your OLR listing on the Upload Manager.
Go to My Listings > Manage Listings on OLR. Click on the camera icon to the right of your listing. On the Videos tab select Embed Video Code. Paste the code and click Upload Video.
The Video will now be available when viewing your listing.
