These are two sources of kitesurfing videos – internet and sports shops. Try keying in the word kitesurfing in your search engine, and you will find hundreds of websites dedicated to the sport the world over. As you browse through these sites, you will see the different features that they post.
Each of these websites contains videos of some sort – exhibitions, instructions, and on some instances, accidents. While these may encourage others to try the sport, there are some who find it discouraging. But I guess the purpose is not to discourage. It is only to make people aware of the dangers that this sport may bring, and that everyone must observe the safety rules that this sport entails.
As years passed, and as the popularity of the sport spread, producers and kitesurfers are releasing better, more dynamic and glossy videos. With new technology, video cameras take better, more precise shots. Worth mentioning is the editing aspect of these videos. Advances in technology allow better editing and dubbing. So aside from just the graphic parts of the video, music is sometimes included to make it more interesting.
There are many kitesurfing videos that you can watch. Whether wave riding or freestyle, there is one to inspire you and teach you as you learn this new sport. Here's a word of caution though.
Don't try to do freestyling or other more difficult stunts for the first time without the help of an expert.
