Here is a clip shot at 120 FPS with a model of the Casio Exilim line that i don't recall the model of:http://www.youtube.com/watch?v=H4SpYKs0MA0

Some of it is slightly lower resolution Samsung and some Casio Exilim EX-F1 the top of the line model in 2009 in the lowest frame rate of high speed function. I think it's 300 FPS. In that Avery Jenkins bit the obliquely downward angled camera is the 512x384 resolution 300 FPS EX-F1 and the level camera is the Samsung with 250 FPS. The video is edited to play at 250 fps.
Indoors too little light filmed with Casio EX-FH20 these are raw data files as produced by the camera so it's not been edited in any other way other than at times clipped for shortness. The resolutions and frame rates vary between the two lowest frame rates. That are 210 FPS at 480x360 and 420 FPS at 224x168. The guy in the videos won masters division Euro Tour in 2010.http://www.mediafire.com/?280v2bo5huc2yzdhttp://www.mediafire.com/?yvocybydfix3w3ehttp://www.mediafire.com/?o41rl4xn23a44p5http://www.mediafire.com/?wwocc1176u2oe5xhttp://www.mediafire.com/?mi7rwgrhw5q741b
With the experience from filming these and myself with four cameras using different FPS/resolution combinations i'd say that 120 fps might be a little overkill for body positions but it will tell timings of the arm pull onset better than 60 FPS. For wrist snap 300 FPS ain't always enough it's a matter of luck if the camera hits the proper spots to show you what's going on. 600 FPS has always been enough for me for wrist snap but seldomly not enough for disc pivot. Any cheap camera has very blocky and details restricting lack of resolution at 600 FPS.
It depends on what you need. Take a close look at 420 FPS 224x168 resolution to determine if you can see enough of it. If not you need a higher resolution. Also take note of the FPS for the things you wanna discover. The worst mistake would be to go overkill for Hollywood stuff or too little for your needs and needing to buy a new camera for more money than a sufficient camera in the first place.
For timings determination it is easier to see the differences in slo mo. In time as the eye is more experienced real time will start to work too. You really need both real time and slo mo.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
