I tried about four different free software packages and beat my head against this for weeks. They just did not work out for me because they were either far to simple or far too complicated. I know my way around a computer alright and have dabbled in editing in my life (but not much), so had a basic idea of what I wanted the software to do but zero experience actually doing this. I needed software that did not take a computer scientist or a master's degree in video editing to use. It had to toe the line between being far too simple and not capable enough, but not overly complicated and tedious to use with a thousand features I would not use.
I settled on Filmora9 and after weeks of soul searching, went ahead and purchased it for $60. Here is a Youtube video for beginners that shows the basics of what the software can do and how to do it. I created riding video about 20 minutes long from about 75 minutes of raw video, spliced it together, separated the wind noise sound, added titles and such, and overlaid music tracks with the video. It took me 3-4 hours to create my first video. What is great is you can really mess things up and it does not ruin the project...just undo back to before you destroyed your work (I did that several times).
It does take some time but is so intuitive that you catch on quickly. It also has an export feature to create all kinds of formats of video, even 4k, and a feature that conditions it for uploading to Youtube if you have a channel. Or you can dumb it down for smaller file sizes, etc...
