Topic: Golf Video Analysis
I have researched and shopped for golf video swing analysis software and can find nothing for under $1,000 that compares to Kinovea. With a few tweaks, I think that Kinovea will be better than the $5,000 packages. Here are my thoughts on how this might be achieved:
1. I would like to build a push button panel that emulates keyboard shortcuts. This would allow me to practice in front of the camera without having to run back to the computer after each swing to watch the video. To do this, there will need to be keyboard shortcuts that switch from capture to replay, a feature that is not currently available. I think that most ofl the other keyboard shortcuts (slow motion, step by step, etc) I need are in the software the now. This is not an original idea. Golf-Tec uses a push button panel like this on its golf teaching software/hardware package.
For anyone who may be interested, the Hagstrom Electronics KE-USB36 keyboard emulator along with 2 inch push buttons that are available on Amazon would allow the keyboard shortcuts to be run by pushing the buttons with the butt end of the golf club.
2. It would be nice if a captured video would move instantly to the replay screen so that there would be no need to go through the steps of selecting and opening the video file to replay it. Using the push buttons described above, you would push one button to record the swing. Then you could push a different button to switch to replay and the video would be there ready to go, thereby eliminating the need to run back to the computer to do this.
3. Having one button to replay two screens (front and back views) would be icing on the cake.
4. The Sony PS3 Eyecams are ideal for the golf swing - they are extremely cheap and capture 75 fps, which is good enough to eliminate blur. CodeLaboratories makes a driver that runs these cameras on Windows. The driver for one camera is free, and it costs $20 to buy two camera support. Kinovea supports the PS3 Eye but the dual camera support is not quite right. You have to load one PS3 Eye before plugging in the second one; otherwise the software thinks there is only one camera.
5. A swing "trigger" would be ideal. Foresight sells a swing trigger, but it costs $4,000. It is a box that starts the video when you begin your backswing and stops the video when the swing ends. There must be a way to achieve this through software, but I don't have a clue how.
I am a tinkerer and am illiterate on software coding. So please accept these thoughts in that spirit. Thanks in advance for any thoughts that anyone is able to offer.
