In all reality, videos will not help that much. You can get a very basic base of knowledge but in all reality, they are about useless. Your best bet is to find a local range with a coach or find a friend that is proficient with archery gear to help you learn. A video can't see you misplacing an anchor point or not properly holding your bow arm or the many different other things that can make a shot less than desirable. Archery can be easy to learn, but it is still a very complex set of motions all formed into one fluid action. There are also many differences between Traditional style archery and compound.
I agree that having a good coach is the ideal option for striving to shoot better in archery. I have been shooting archery rather regularly for about a year now. I have received some good coaching and advice during that time. However, the bulk of my practice time is by myself. Consequently, I felt a quality instructional video might be a nice resource to mentally refresh optimal shooting techniques from time to time to try to ensure that I get the most out of my practice time.
Along the same lines of trying to maximize my solo practice time, I used my digital camera to record myself shooting. It was more difficult than I thought to spot problems since everything happens so quickly, but I was still able to spot two problems with my technique. Just trying to think of new ways to keep improving.
Hunting is not usually a pursuit where instant gratification abounds. It takes a lot of time, practice, resources and patience to be a successful hunter. So when someone decides that an area they hunted only once without taking an animal is worthless and devoid of game, I don't quite understand it. These people usually jump from game management unit to game management unit; trying a new one every year.
Now don't get me wrong, there are people that just enjoy scouting and hunting...
