My new GoPro Hero 9 can shoot at 120 fps which makes for some great slow-motion video. I set it up in front of our bird bath this morning and let it run for about half an hour. It took no time at all to find a bird in the frame, crop the footage in time and size and then reduce the speed to 20%. Here are the results.
It's fuzzy because the camera was too far from the bath. Here's a still from the raw footage to give you an idea of the shot.
For some screwy reason, the GoPro doesn't come with an adapter for a standard camera tripod, or if it does, I'm looking right past it. In any case, the solution is to move the camera closer so the bath almost fills the screen. I'm betting those results will be most satisfactory.
