My GoPro suggested I need new clubs-shafts - momentarily

[Midpack]

Many of you know this already, I didn't until yesterday. And others have shown it on YouTube. A strange phenom for those who haven't discovered it.

I am relearning golf after a very long layoff, and I took my GoPro to the driving range yesterday. I set it on the fastest frame rate (60 fps), hoping I could slow it down on playback and examine my swing, and it was somewhat useful. I hadn't planned it beforehand but just for fun I started looking frame by frame, and I was ALARMED for a few minutes. At the start of the downswing the shaft is bending back some, makes sense. But just before the clubhead makes contact with the ball, the shaft appears to be significantly curved forward, that makes no sense. W T H ! It's even more exaggerated with my driver, but the graphite shafts are dark and much harder to see with the background, so I used pics with my 5-iron. For a minute I thought maybe I needed different club shafts (mine are stiff)!!!

 

Sorry honey, I'm going to HAVE to buy new clubs. Feel free to use this trick if you wish.

But I Googled (what did we do before) and learned that unless the camera is truly slow-motion capable, there are some crazy distortions that occur - that bear no resemblance to reality. Has to do with rolling shutter, frame rate and/or shutter speed - I am sure some experts here know already know all about the phenomena, where I did not.

Anyway, I still learn something every day...

Yes, that's correct.

We had an old thread we used to refer/merge everything into about this topic, but it didn't transition well from the old software so I'm not going to link it.

@MidpackAfaik:

The camera takes a photo left-right/top-bottom or vice versa. Basically it takes a slim slice. Now if the target is fast enough the target will be in a slightly different position in the next "slice" and thus distortion occurs.

I think it looks okay.

This is to do with scanning rates of cameras. It's the same thing that makes helicopter blades look bent when shot on video.

Yep, no problem. Even though the shaft will, indeed, flex slightly that way at impact. Just not as much as what the camera shows. There 's an old photo of Nicklaus coming into impact where his Driver shaft looks like a banana!
