Hi @severino_gervac ...
Unfortunately, to my knownledge, there is no current way on the front-end UI (user interface) of Canvas Studio to download media (audio/video) in a batch process. Further, when you do download media individually, you can only download media that you have created yourself or files you have uploaded. You cannot download YouTube or Vimeo videos that you have added to your Studio library, for example. Sorry that I don't have better news for you, but I hope this helps to answer your question.
