Thanks Boyersj. I think I need to get a good tri pod (to sit the camera on) and maybe a better camera. All I have right now is this old nikon coolpix 16mp camera, but it does record video. I think I need a much better camera.
I had been searching for the best (and cheapest) camera for videoing me and my buddies play. In the end it turned out I had the perfect solution in my pocket the whole time, my smartphone. I have an LG G4 which has one of the better cameras among smartphones, but it does an excellent job even though I use the lesser, front camera, rather than the much better rear camera (using the front, with the way I mount it, is just easier and the quality is still excellent).
I bought an adaptor for about $5 to hold the phone and give it a standard tripod screw mount. After that you can use a tripod or any number of other mounting options. I use a couple of things I had lying around from one of those gopro type cameras. My phone takes a 32Gb micro SD card. The video files seem to have a 4 Gb limit and that gives me about 45 minutes of video. But then all I have to do is hit the record button again and it starts with a new 4 Gb file. For power, I just use one of those power banks with USB connectors, plugged into my phone while it is videoing. I've never run out of juice, and when I am done the phone is generally still fully charged.
So, you may already have that better camera you think you need. My sense is that all smartphones have pretty good cameras for this application.
I'm planning a lesson with Scott Lee next time he is in my area, and he told me he videos the lesson and gives you DVD(s) of it, so I will be interested to see how his video set-up compares to mine. I've thought about posting video and asking for suggestion, but aside from the embarrassment factor (I'm not very good) I figure that since I am planning the lesson I should be patient and wait for that, rather than possibly getting off track with online advice.
