Now you can import videos from Google+ to YouTube. This feature was announced by Google in the YouTube Help Forum.
If you are a Google+ user who has uploaded quite a number of videos to share with your circles, you can now import these videos to YouTube. If you have merged your YouTube channel with Google+, you will see a new import option in the upper right corner on the YouTube upload page. When you click on the “import” button a new window appears which shows all the available Google+ videos which can be imported.
You can import the videos one at a time or in bulk. YouTube gives you the chance to edit these titles as well as other attributes. You can also set the imported videos to private.
Google has also shared a video explaining how the new feature works. Brands and marketers who are active on both Google+ and YouTube will find this a more convenient way to get video especially auto-uploaded ones stored in Google+.
