Unlike images, you are not able to upload video files into Creator Studio - however, you can still add videos to your Experiences using either our Embed Widget, HTML Widget, or YouTube Widget.
Before doing so, you will need to upload/host your videos using any video hosting platform that is available to you (i.e. YouTube, Vimeo, Brightcove, any internal servers, etc.).
If you are using YouTube, you can easily search for your video using that Widget and add it to your Experience. You can also login to your YouTube account to pull in any private or unlisted videos that you may want to use.
If you are not using YouTube, then you will want to get the URL for the video or the embed code for the video and add it to your Experience via the Embed Widget (for URLs) or the HTML Widget (for embed codes) accordingly.
