A great camera to record a golf swing is the Sony DCR-SR220 60GB Hybrid HDD/Memory Stick Camcorder. It has a slow smooth recording feature which is like a poor man's Swingvision, which shows your swing in super slow motion.
It records 3 seconds and plays it back in 12 seconds. It's not as good as Swingvision, obviously, but given it's price point, which is quite affordable, it's pretty good.
The big downside is that you can't record your swing unassisted. 3 seconds is not enough time to hit the record button on the remote and get a full swing recorded by yourself. You'll need a buddy hit the record button and it has to be timed well. It would have been nice if Sony made a delay feature or upped the 3 seconds to 10 seconds.
The fastest shutter speed is 1/8000th which is plenty fast to capture the positions in a golf swing. Today, you may want to upgrade to an HD camera. I think 1/4000th shutter speed would be good enough to capture the swing. Just spend enough money to get a camera that produces a good picture.
2. Tape a swing when you set up your camera to be sure you've been able to record it correctly. Be sure you can see the clubhead throughout the entire swing.
3. Tape drills for b-roll as well as real swings.
4. Some people like to see a golfer's pre-shot routines to see exactly
how they prepare for each shot.
5. There are some positions that you definitely want to include in the video: setup, takeaway, halfway back, the top, delivery, impact and release.
6. If you can incorporate the golfer's swing into your PC or laptop and use some of the computer golf coaching programs that are commercially available, it would make a nice enhancement to the look and feel of the video.
7. Get a camera that is capable of slow-motion capture in order to analyze the swing, or create slow motion while editing- the feature can easily make it able to have the expert provide voice over analysis as it happens.
8. Shoot plenty of close ups for b-roll later.
