Serious golfers use Tapatalk.
![]() Just wondering if this is normal or is my shaft kicking forward to soon in my swing? My ball flight is where I want it and goes as straight as I could hope for about 80% of the time. However, I'm thinking if my shaft is kicking forward too soon in my swing then I could be losing distance off the tee. Not that I think I'm some crazy power hitter, but it just looks odd that my clubhead is getting near my legs when my wrists are still cocked parallel to the ground and haven't released at all yet. Shaft in the swing is Diamana Blueboard Stiff on my R11. |

What you are seeing is an artifact due the digital camera and how it takes pictures. That shaft bend is not what it really looks like. I copied this from another forum:
*** Jello Effect. High speed video cameras that use a rolling shutter are known to produce some distortion, the Jello Effect, because different parts of the frame are captured at different times. For example, the top elements may be exposed earlier than the bottom elements. Still, each element/pixel of the sensor is exposed for just the shutter speed of, say, 1/5,000 sec. Cameras that use a global shutter capture all areas of the frame at the same time and do not exhibit Jello Effect. Some or all of the Casio cameras are CMOS cameras and probably have some degree of image distortion depending on how the sensor array is readout. Getting information on the distortions produced by particular models of cameras is more difficult than finding descriptions of the Jello Effect, rolling shutter or global shutter on the internet. I recently purchased a Casio FH100 and wanted to know how much it distorted my images. To check this, the camera at 240 fps viewed a rotating disc with a thin straight white bar across the diameter. The bar extended across the camera's field of view. At 550 RPM or 3300 degrees per second, the straight bar appeared considerably curved. The curve caused the end of the bar at the bottom of the frame to appear roughly 7 degrees ahead of where it would have been if the image of the bar had remained straight. The arm/golf club does not rotate around the shoulder as fast as the tested bar. A 100 MPH golf club head located 5 ft from the shoulder rotates about 1700 degrees per second. The test bar rotated at about 3300 d/s and a golf club rotates at about 1700 d/s so the bar was twice as fast as the golf club. I would expect the club bending to be about half that of the test bar if the shoulder were in the middle of the frame and the golf club head at the bottom – club head leads by 3.5 degrees. That's for a Casio FH100 at 240 fps. This was a quick preliminary test and first estimates. Both club bending and camera artifacts are probably present in your swing picture but I believe that most of your extreme curve is from the camera. As suggested by others this can be checked easily by turning the camera upside down, repeating the video, and then comparing the direction of club bending with the camera upside down to bending with the camera right side up. If the images show the same bending then the club is bending. If the bend reverses then it is an artifact produced by the camera. *** |

I just asked if this was normal. If there was another thread about it feel free to merge. Your comment didn't really answer my question though. |
