For those of you who compete and record your matches, I'm curious to know what kind of video gear (camera, camera mounting system, supporting software, etc) you use? Based on your experience, what would you say the minimum camera specs should be (frame rate, resolution, other features)? Anything in particular to avoid? Is everyone just running GoPro cameras? Anyone try some of the smaller wearable cameras? I'm not looking to become an "influencer" on social media. I just want something good enough to capture what I did, so that I can review my actions and improve my technique. I assume that I want a head mounted rig rather than a chest/body mounted system.
