How do I delete a video?
To delete a video you have uploaded to the site or added from the search until December 28, 2014 (the video section update), click on the pencil icon in the upper-right corner of the video. There is a “Delete” button in an opened window.
To delete videos, added to your list from the search (after the video section update), click on the cross icon in the upper-right corner of the video.
Unfortunately, you cannot delete all videos at once.
