Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I was going to post this on the Golf Talk thread, but I thought it might be interesting for other amateur videographers or applications.
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 for players)!!! Sorry DW, I HAVE to buy new clubs.
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...
