I want to take videos of DD hitting in game situations. Will be behind the fence. I know nothing about video cameras and have limited $$. Would like to be able to do frame by frame comparisons. I need help.
Whatever you choose, you will need something small enough to get the lens in the middle of the fence opening. This will help you keep fence out of the shot. GoPro is our prefered camera. They range somewhere between $200 to about $500. The Hero 4 Silver, is the one we are currently recommending to customers. Here is the setup we suggest with this camera: LynkSpyder Configuration for the GoPro Hero 4
Check out Casio I film using 30-120 fps or 30-240 fps I like the high speed video. You have to film manually with the Casio unlike the Go Pro which I belive you can operate by a app
I use a GoPro Hero 3+ Black, and, like everyone else says, these cameras work well. But there are other options that might be less expensive. If you have a smartphone, I'd see what you capture with it first if you are concerned with just one hitter as opposed to a whole game.
For comparing swings, as L.J. mentioned, the frame rate is key. Faster frame rates make smooth slow motion video, or at least give you more frames to choose from when stopping video for your comparison. 120 fps (frames per second) is good, but 240 fps is better. If you end up camera shopping, that's a feature you probably want to keep in mind to break down at bats. If you try a smartphone, select a high frame rate option for video if you can.
