In TwentyThree we do not only host the videos but also the full design of a video website and video player. This means you can upload any asset file or other graphics under Site Designer → Files.

To upload a file you can either use the Upload file button to select a file you have stored locally − or you can drag in files directly to the browser window and drop the chosen files on top of the file list. A file that has been uploaded will always be available for download.
