When you tweet a Vidyard video, your followers can watch the video right in their Twitter feed (no need to navigate to a different page)! It's good to keep in mind we display the thumbnail image of your player on the Twitter feed (learn more about how to change the thumbnail of a player).
The video that you share must have been uploaded to Vidyard directly (not a YouTube import, for example), and not be secured by access codes, request managers or IP whitelists.
Also note that Twitter caches the thumbnail and metadata from your tweet for 7 days. Any changes made after you post will only be reflected after that time.
