2D Video: How Should it be Used?

[kc8kir]

Ok, so we all know the detriments of misaligned and misused 2D video. So how should it be used? Is there a view that would be particularly useful?

My dad had the idea recently to setup a camera on a PVC stand that could take overhead video. This way you could actually watch the clubhead path parallel to ground plane. This view is seen in a lot of golf books, but rarely seen in teaching practice. Would this view be useful, especially for path correction?

In my mind, the components of path and angle of attack can be reasonably observed from overhead video and front video (respectively). Face angle however... that is something else...

Thoughts?

How about putting a camera on the bill of your hat like the tiger woods videos on youtube. The golfer's view is pretty high on my list although I have not tried this yet. For the golfer, his view is most important. Maybe with some good slo mo video you would be able to see what swinging left looks like to the golfer.

Now why would you want to do that? You'd mess up all those people who still stay you have to keep the head absolutely still!

Lol.

I don't think you'd be able to detect the small amounts of change needed for each component on normal video.

I think the best way to use video is to see the real vs. feel of positions that you may want to get to in the overall picture--no need to draw lines.

Yes,definitely good to highlight feel vs real.I think 2D video can still be very useful as long as the camera is positioned correctly and always in the exact same position.Directly front on(caddie view),looking down the line of the hands at address(DTL),around waist height and far enough away to minimize parallax.

I was fortunate to learn from a man named Carl Welty, whom I feel has been ahead of the curve in my experiences (eg., correct ball flight laws, upright lie angles, parallax). Some people refer to him as the pioneer of golf swing video as he has been filming tour players for half a century really. Anyway, one thing that I took from observing him is that he is very specific with his camera angles and heights, and distances for that matter, but he is also very creative. He would often film just the feet of a student to make the student focus on thier footwork. Long Post Short, I use a camera as a training aid for the student to better understand what they are doing, and as a reference for former and future clips. As you all know, it's imperative to make sure all settings are the same for comparison clips. As for the camera from above, it's becoming more common with the new learning centers being built. According to Trackman you can not track angle of attack with a camera (therefore true path is not trackable either) which I would tend to agree with in general.

Sounds like an interesting guy...I am just leery of someone who thinks Sam Snead comes over the top and compares Snead's swing to Craig Stadler.

Just a couple of comments. I bought a nice camcorder a couple years ago. I researched the internet and found some seemingly good instructions as to correct camera placement etc. Problem 1.

Patience. It takes some time to set this up properly. That's just for one position. More time to change the view from say down the line to face on.
I pretty much ran out of patience.

Then there is the challenge of doing this alone. It would help to have two people participating. However, that brings in the inevitable additional opinions thing.

I bought the c-swing software, but used it mostly for the swing library of pro swings.

So now I got a Casio FH-20 at x-mas. It's ease of use coupled with the high frame rates make it more likely that I will actually do something useful with it.
I tried a couple of sample movies at 210 fps and then ran them on c-swing. The program allows you slow down video to a crawl. So if you are starting with slow motion, you can go really, really slow.

My thoughts about how I will use the camera run along the lines of real versus feel. I think I am doing X, but I am doing Y. I think it also will be useful to pick up unconscious things I do in pre-swing routine. It will not
record sound at high speed settings. So I am going to do some hand signals to communicate perfect , miss right etc. I may also try Brian's thought about
putting the camera very low to the ground and capture the driver angle of attack at 1000 fps, i. e. how do you know when you are actually hitting up.

I also want to capture what I do on a clearly bad swing versus a clearly perfect swing based on ball flight results. Would love to capture the out of rhytm kill driver swing that goes wherever it chooses versus the seemingly slow rhytm driver swing that is sweet spotted, and goes farther.

On the other hand, I may once again, not have the patience and relegate the camera to shooting normal pictures. We shall see.
