Will videos created with client.videos.create(videoCreationPayload) be deleted automatically when upload is missing?

I wonder how to handle video elements that has been created beforehand where the upload has been aborted (user leaves site, or aborts himself).

As i understand: to create private videos you would create a video container with public: false, and then use the videoId to do the upload associated with the given videoId. Now when the user e.g. leaves the site, the upload never finishes, leaving a video container which has no content. How can I keep those video containers clean (delete those video containers, where no upload has been done)
