Some good advice already..........Audio is just as important as video,without good audio your footage will suck.It is definately way harder than it looks, animals rarely follow "the script", you will find that you will have to hunt twice as hard to get the same opportunities you would hunting w/o camera/cameraman in tow. Strive to be staedy at all times.......there is nothing more frustrating to watch than jerky unstable footage, a good camera arm and fluid head is a must. Think of zoom as a transition change, in other words don't go in and out as the animal comes in, zoom close when it is close to the tree and zoom back out after the shot............I will disagree the shot is not the most important part of the hunt, laying down a good visual and audio story is THE most important part of videoing a hunt (unless you are putting together a kill shot video)........LEARN your camera and it's manual functions INTIMATELY. you might have the best camera in the world,but if you can't operate it properly your footage will still suck,use manual controls as much as possible because shooting outdoor video the settings are constantly changing...............I have a blog on my website that might be helpful : http://www.pronghornproduction.com/tapingyourownhunts.htm.

Good luck
