As a creator of Panopto recordings, if you navigate to your Canvas Course and click the Panopto recordings tool, you will see a menu for creating new recordings. Recordings and webcasts are automatically uploaded and published to the associated Canvas course Panopto folder. After you have created a recording, it uploads automatically.
When finished uploading, refresh the Canvas browser window and you should see your recording. You now have additional options to edit, delete, or move the recording to another course folder.
