The true name in the camera industry is rolling shutter. If you want to do research on it use rolling shutter. Jell-o effect is a youtube name that has been used to describe the effect when the camera is running in video mode.

I could go into a long description of what rolling shutter is, but the web does a MUCH better job.

I saw some slow motion video of my golf swing and I noticed my golf shaft was looking like a rubber band. In the pic below, I'm using a 5 iron, with a Dynamic Gold, True Temper S300 shaft, that has been spined. My ball flight is a bit inconsistent at times, but more often than not, I hit a low to medium-low- trajectory. Is this level of shaft flex normal or should I be playing something stiffer?

We've discussed this in the past. It's how the camera shutter works. It reads from the top down, so the ones farther down are taken a fraction of a second later, which allowed the shaft to move that much farther forward.

In other words, your clubs aren't actually flexed like that.

Thanks for the reply.

Does it matter that this is a screen shot from actual video footage as opposed to a basic camera pic? I've looked at many online videos of the pros and I never see THIS level of shaft flex in their clubs, below is a freeze frame pic of Tiger also hitting a 5 iron.

The higher the shutter speed, the less distortion you will tend to get. If a camera only needs to shoot 60 FPS, it could take 1/60th of a second to read from top to bottom. That's an eternity.

And you can see even in the Tiger picture his shaft is flexed forward. If anything the shaft would be flexed slightly the other way.

I want to make sure that we're talking about the same thing. I understand what you're saying about the "distortion" issue and the FPS, my question is wouldn't a stiffer flex shaft show less distortion on camera?

You bastard.......if only for playing golf in December in warm weather.

Aside from possible camera tricks, a club bent that far forward at impact may suggest the possibility of casting and releasing the energy and speed well before impact............

Have you had your driver clubhead speed accurately measured?  Tempo matters, but you probably wont require X-stiff unless you are 110+.....

If it was a casting issue, the shaft angle would've been lost a lot earlier in the downswing...  The hands are already at the ball with lag still visible. Clubhead speed is between 107-111

Lookin' solid Iziah....

The shaft is still bent forward well before impact.  Maybe that's what separates us AMs from the pro's?.....maybe it's due to the camera......maybe it's a slight timing issue with the release?  Pro's miss big too.....if you see a pro with a shaft bent that far forward, that shot may have ended up in the trees.

this is ultimately what you want to strive for....

A club that is bent severely leading to the ball.......and lagging/ whipping it's way to a straight shaft at impact= big power. An early release will send the ball offline and lose distance.

Do you hook the ball?

That is definitely an ideal looking shaft at impact....is that Jack? I may need to sample some different shafts and pay my instructor a visit, thanks for your input

Informative video.  I had no idea that shaft was actually straight.  So I guess we've found yet another difference between us and the pros:  better cameras.

Erik was right its the shutter speed of the camera.  In those photos the camera had a low shutter speed.  Watch some youtube videos of pros with the high speed cameras you won't see that.  It's an illusion not really happening and nothing wrong with the shaft or the swing to cause it. Also if you are hitting the s300 low an x100 woiuld go even lower so that wouldn't help your ball flight.

No.

A slower swing speed would show less distortion.

    • He's not and GEARS doesn't really measure toward your midline. It's measured at the joint. That's not why his use of "midline" is bad (part of the reason is that your "midline" is twisted, the top of your sternum can be pointed at a different place than the belt buckle, and your shoulders protract and retract, too. I think he's just trying to use midline to say which way the arm is moving. But they have terms for that — adduction and abduction — so whatever.
    • They weren't necessarily short - I don't remember the exact specifics of all of it, but some of them were missing a little left or right or both. Day 1 they were landing on the edge and kicking on, where day 2 they were just missing and kicking down into the bunkers and did it a lot. I think all told I actually went into bunkers on 8 holes. Some of them were not good shots. Like a few examples, on 8, the pin was in the back. I hit it solidly, but pulled it and it went long, over the bunker into long grass. I had the ball in sandy earth with long grass around it and about a foot below my feet. That next shot I tried to do what I could but it went into the bunker in front of me. Into a footprint. That one I dug out of the footprint, but still in the bunker. Got that one out of the bunker, but into the fringe grass in front of me. Chipped that one on a bit hard and two putts later made a 7. Another was on 14. The flag was on the little finger of green front left. I tried to play a little past it and a little right. Shoved it maybe 10 yards right of where I wanted to and the carry over the bunker gets longer the further right you go and that one hit the grass between the green and the bunker and came back down into the sand, left it in there and didn't get up and down on the next one. I think carrywise it carried about as far as I was planning on it doing so. Another was on 6, leaked my drive a little right into the fairway bunker. Hit a nearly good shot from there that went a little left and a little short and kicked into the bunker front left. That was a strike thing and just a hard shot. Did similar on 18. Drive in the right bunker, slightly heavy second that hit the bank between green and bunker again and kicked back into the sand. I think the tiredness manifested more as not squaring the face up so well and less as slowing down.
    • Depends on how short you were coming up on these shots. A bit more wind? Also, maybe you were swinging at 2-3 mph slower the next day.  I think the biggest thing is not adjusting. Like making assuming your stock shot is not enough and taking 1 club up. Not sure what type of adjustments you were making in your decision making. 
    • No one should measure a joint mobility away from that joint. If you go to physical therapy, they are not measuring your knee mobility based on your midline. It is based at the joint. Shoulder mobility should be measured in reference to the shoulder joint. 
    • He's using a driver swing, while I used the iron swing. Bryson goes from about 65° B to 15° B, hence the 50°. If you bend your right elbow, you're going to pull your hands across your chest some. Conversely, if you abduct your right arm and hold onto a grip with your left arm, you can see how extending the right elbow as we do in the golf swing during the downswing will "pull" the right shoulder/humerus forward (adducting it, as going from 65° to 15° of abduction is). Even people who pull their right shoulder WAY too far around them eventually get it "back in front" when their right arm/elbow extends. So, such a motion shows up as shoulder adduction even though the movement that causes it is just widening the trail elbow. The left hand on the grip almost "pulls" the hands forward as the left arm can't stretch much (there's some shoulder protraction, but that's almost maxed out at P4). Oh, I downloaded it and watched it (and commented there) before he blocked me. It's what led to him posting the comment in the "update" above. 😄  Single shoulder range of 75°, and that's going out well into the follow-through. 50° Max range up to impact. Manavian's video is bad. He keeps saying "midline" which is just a horrible way to look at it. He also kept saying that the club was moving that amount — also wrong. Adding left and right together is really freaking dumb. Another golf instructor said "That's like saying the player has 100 degrees of knee bend (adding left knee bend to right knee bend) 🤦‍♂️" (similar to what the biomechanist said about squatting). Also, see my post above about elbow bend. That's why Plummer’s alignment stick demo is so intellectually dishonest. A golfer can't get anywhere near that position on the left with his left hand on the alignment stick (quoted below).
