Saving Mp4 video from within safari

Hi,

I have a link to a video that plays within safari, however, instead of watching it through safari i would like to download the video so i can watch it offline/ and have it permenantly.

I have tried right clicking on the video when it plays but couldn't find 'Save as' or anything similar.

I was wondering how is it possible to download this video?

Here is the link if it helps, its a golf program -

Many thanks for any help and suggestions.

Tom
