So you've successfully created a new Artwork video and are ready to download that file. Nicely done. 🙌🏻
There will be a download button next to each video on your Videos list page. Depending on which browser you are using, clicking that download button may have different results. On Google Chrome, it should, well, download straight to your Downloads folder. However, other browser may just begin streaming the video right from within the browser. Not quite what you had in mind, right? In those instance, you should right-click (or hold down control and click) and choose the "Save File as..." option. Note this option may be named differently depending on your browser. For instance, it's named "Download Linked File as..." on Safari. In the end, you should be able to get that file onto your computer and ready to share.
iOS devices like iPhones and iPads do not allow you to download files from your browser. Instead, you'll want to download from your computer and then transfer your videos to your phone.
