My suggestion is to just keep working on it. I started putting together year-end videos in 2010 just as a video "hunting journal" for myself. I have expanded that to short YouTube videos as well. I was working with pretty limited equipment over the past few seasons. First I didn't have a digital camera so I couldn't upload anything from my camcorder (that was early 2000's). Then I got sick of my camera arm because I was focusing too much on that and not hunting. For the past few years I have been using a Kodak Sport handheld camera (about the size of an iPhone), but that was limited in what it could do. I broke down and bought a Tactacam about 2 years ago. That changed a lot. It is so much easier to hunt and still get video because it mounts directly to your bow or gun. This year I have upgraded to a Canon t6 camera and just bought a Muddy micro camera mount. I am hoping that the combination of those two will greatly impact my quality.
As far as editing, that is a monster in it's own right. There are so many different softwares out there. If you are just starting, I would suggest the simplest, Windows Movie Maker. It is a user friendly platform and great for learning. I personally use Adobe Premiere Pro now. I also majored in Broadcasting in college and used Adobe Premiere for my classes, so it had a lot less learning curve for me.
Just keep plugging away and my last piece of advice - shoot way more video than you think you should. You can cut it down when you edit it. It's better to have too much than too little.
