Vidyard provides the ability to push your videos to YouTube. This can help to ensure that your videos have as much visibility as possible to the public and suits some video strategies.
After you have pushed a video to YouTube, you see a message on your company's Twitter with a notification of the video being added to YouTube. This may or may not be something that you wish to have set.
This is not a function that Vidyard provides and is caused by a connection you have between your YouTube channel and Twitter accounts.
You will need to adjust the 'Share your public activity to connected accounts' settings within YouTube.
Once logged into your channel, this can be found under Account Settings > Connected Accounts.
Ensure that Upload a video is unchecked if you do not want to have information tweeted about new videos.
