I use the free GoPro Studio software and learned a few video edit tricks (like slo-mo) watching youtube how-to's. Some don't like GoPro stuff but how else do you film the hunt and get to hunt? It is fun stuff plus when I get alzheimer's I can relive every hunt like it never happened.
I think, depending our long I want to monkey with it, the videos take me a couple hours to finish. Go to free music sites to get royalty free music for the videos. If I just simple edit (no special effects) and splice the videos together, edit time is prolly about 30 min for a 15 min video. Upload to youtube can take some time. It can get slow and fails sometimes. Hope this helps. Thanks for watching!
