To keep download file sizes down we're now just hosting all our videos on Vimeo so that you can preview them and download the ones you want to share:

If you're sharing to Facebook or other social media platforms it's best to download the video then upload the file directly to your post (if you just post the Vimeo link it won't play the video on Facebook).
