Golf Swing Analysis Software?

Q. I am looking at getting software that I can use to analyze my golf swing, as well as my son's batting motion. What is the best software that is reasonably priced for personal use?

A. The best possible software that you can use is the

V1 software.
You can get it for free for the basic modem, but if you want more advanced, you can pay a little bit more money for the premium. If you do the premium, they even have the camcorder use for your swing.

I use v1. I've been using it for 3 years now.
It's great for analyzing my own golf swing or any sport or kind.
It is the program that the Golf Channel uses for the analysis for the golf swing.
They even have models for you to download.(If you are premium). They have swimming, golf, soccer, football, you name it!
as well as baseball.

Get V1 software at

www.v1golf.com

Hope it helped


what should i film in for smoother motion quality?
Q. like less lag.

720 HD 60p
-or-
720 HD 30p

and if you say 30p should I have SteadyShot ON or OFF
none of these answers are answering my question. just answer the question and choose one

A. Hi Mikey:

It looks like you may have upgraded camera gear since you asked about your CyberShot DSC-H9 a couple of years ago, since the H9 doesn't have any 720 HD settings (or HD settings at all!). But since you mention SteadyShot, and not the generic term O.I.S., you must still have a Sony model.

And since you didn't say exactly what kind of motion-footage (there's a difference between shooting a golf swing and shooting a car race -- the first, you might want each frame crisply frozen in time with no blur for analysis; the second, you might want the cars to actually show some motion-blur), I'll assume you are still shooting skateboard videos. Some of this is frame-rate, but mostly it's actually the shutter-speed (the DURATION for each frame, not how many in a second) that helps determine how the footage appears during playback.

And speaking of skateboard shooting, are you shooting POV while on the board? If so, SteadyShot might be useful. If you are shooting others on their boards, your camera should be on a tripod with SteadyShot turned off.

As far as frame-rate, it can be more a matter of taste, as you can see in this "720p30 vs. 720p60" discussion a few years ago on Videomaker.com: http://www.videomaker.com/community/forums/topic/720p30-vs-720p60

But if you are wanting to have smoother slo-mo action of skater stunts, go for 60fps. Just keep in mind the bigger file size (twice as many frames), and for some cameras the compression to handle twice the data (at 60-progressive) will result in more digital artifacts in the final footage. (For typical consumer cameras & camcorders there's got to be a trade-off somewhere.)

And speaking of bigger files and twice-the-frames, what you are calling "lag" might be referring to your computer's playback of the raw footage. Many consumer shooters' computers (especially laptops) are sadly under-powered to handle ANY kind of HD footage without "lagging" or stuttering. This has nothing to do with camera settings, other than decompressing twice the frames as well as the huge HD data might be choking your PC.

But if you have a CMOS sensor camera, and are mistaking "rolling shutter" (a/k/a "Jello effect") for "lag", neither setting will cure that problem: see http://en.wikipedia.org/wiki/Jello_effect

You'll have to make the final judgement, but my best advice: Do like the pro-review mags & websites do & shoot some test footage with the various settings. "Slate" each sequence with a large card or paper sheet with Marx-A-Lot, noting stuff like "720p @30 StdyShot OFF w/ 1/250 shutter". Then you can render each one and decide which one "looks best" to you. Hollywood cameramen have been shooting "camera tests" since the silent movie days.

If you care to discuss what you exactly mean by "less lag", feel free to post another Additional Details update, and we can take it from there. (Also post your camera model # and what computer model you are using.) And if this whole discussion is just "hypothetical" because you are camera-shopping and want to decide between models with different frame-rates, please say so. Clear "context" is important to any technical discussion.

hope this helps,
