Hi Iggy, try this. Google "air brushing for beginners" and click on the first one at the top of the list,this might be of some help,by the way it is not a video. I use one,so I would say you will pick it up quite easily. Is it a double action one you have?. Using one is like scrolling, practise ETC ETC ETC lol. Hope this helps in some way Iggy.Good luck.
