How do I save my downloaded video to my desktop of my Mac?

I want to download the video to my desktop so I can drag and drop the video to my powerpoint (Keynote) presentation. How do I do that  from my downloaded video which is now located on Televzr?

If you want to download the video directly to your desktop, while you can not do it, the video is downloaded to the default folder.
If you want to drag the video to your desktop, just transfer it.
