The Media Library is your central store of every video in Storista — synced, uploaded, and tagged. Uploading within a widget adds the video to that widget and to the Media Library simultaneously. Use the Media Library to upload and tag in bulk before deciding where videos appear; upload within a widget when you are building a specific placement.

Open "Media Library" in the sidebar and click "Upload files"

On the widget page, click the "Add content" button then click "Upload files"
