How to identify if videos in a collection are available on elements

Hi All

I created a collection of 150+ videos for a music video, before I realised that not all videos are available through elements. Fortunately many of the videos I selected are available but:

  1. Is there an easy way to identify and segregate videos in my collection that are available through Elements?
  2. Is there an easy way to download video previews for a collection, rather than downloading individually via each video’s product page?
