Hi @SamiyyahKNew ...
Are you asking how to add multiple videos to your Studio library at one time? If so, there is no way to do this from an end-user perspective...as far as I know. The only way to add videos (either ones you've created yourself or links from YouTube/Vimeo) are one at a time.
Sorry I don't have better news for you, but I hope this helps to answer your question.
