I am still using a Sony HD Handy Cam or a GroPro for action work.
I dont dare get a more expensive camera due to accidents with the camera falling over. It seems like I go though a tripod every year due to crashing down in the wind.
The old Sony takes a beating though and keeps going.
Another YouTuber once told me to get Filmora Wondershare and I love it. Works for me and it was affordable.
