Video Analysis Software for Tennis Strokes?

[Chas Tennis]

I have a Casio Ex FH100 high speed video camera. At 240 fps it shows my strokes very well with little motion blur.

How I'm viewing videos now.I use the free version of Quicktime to do frame-by-frame analysis. To measure an angle I put a clear piece of plastic on the screen, trace the angle with a Sharpie and then measure with a protractor. I could also trace the motion of a body part or point on the racket in a series of frames.

I would like to get some software to improve analyzing the high speed videos. I would use the software only for analysis of my strokes and maybe also a few friends, so cost is a consideration.

A few desirable capabilities for the software-

1) Side-by-side: my stroke and a pro stroke. Or before & after my strokes.

2) Add text notes to saved videos.

3) Add marker points to body parts or racket. Lines for arm position, etc.

4) Show superimposed marker positions for several frames, i.e., elbow angle or racket position.

5) Lighten or darken video.

6) Edit videos.

7) Please supply others that you think are useful.

If anyone has some experience, good or bad, with sports analysis software as applied to tennis please reply.

If the software that you are now using replaced some other, what were some of the strong points of each?

That software is available, but it is very expensive.

dartfish .........

^Yeah, our club pro just started utilizing Dartfish. Did a free trail with it and it's pretty cool, but the big thing is that you need a pro/coach that can analysis your strokes appropriately. Just looking at it yourself, if you're not sure what you're looking for, it's basically useless.

The pro charges $60/hr for the Dartfish lesson. I haven't gone through the full run, but if I do, I'll report the experience.

Free Kinovea Sports Software for Stroke Analysis

Started using this morning and this free open-source software from Kinovea does a nice job for the functions on my list and more.

(FYI, After I downloaded for my computer I had to also download from Microsoft both .NET Framework 4 and the earlier NET 2.0 as discussed in a Kinovea forum - http://www.kinovea.org/en/forum/viewtopic.php?id=250)

I paid the $2400 for dartfish and loved it. Then I lost my hard drive and my laptop got stolen and they only give you 2 licenses. So I switched to kinovea (like he said its free) and I like it. They are constantly improving it too. There are a few things I would like to see changed but if you ever need some tips on how to use it go to my blog below and email me.
