You can find a number of free hour long training videos for indoor cycling on youtube.com like this one. Shot with a Go-Pro HD camera mounted on the handlebars or the rider’s helmet, they can compliment your catalog of more professionally produced videos.
My experience is that helmet mounted cameras are great when used in moderation and on smaller screens. The amount of side to side motion is unsettling to many people, resulting in feelings that resemble sea-sickness 🙁
If you were looking for video for use in a Spinning class, shown on a large screen with a projector, I suggest you look into the very stable videos from Virtual Active (rock solid) and Epic Planet. If you have an Amazon Prime Membership you can stream dozens of free training videos.
