While your video is being transcoded, you'll see a red 'Processing' to the right of its title on the My Vids page. 

Also, if you go into the Edit Page, you'll see a message on top of the video that tells you it's not ready yet. 

However, you will be able to grab your embed code in the meantime, so you can start placing it on your site while you wait to customize it. 

Please note this process may take up to 30 minutes for some files.
