You and I have paralleled each other both in commercial piloting, drone flying, and photography. For many years, I shot with a Hasselblad 500C, and at one time owned a photo processing lab. When my interest in drones surfaced, I learned that my aviation skills did very little to prepare me for drone flying. Likewise, my photography skills helped only with basic composition and exposure. The learning curve for cinematography was ultimately steeper than the flying part, and I struggled initially. Once over "the hump", things became easier.
I would, for now, forget about Dlog. Start with the standard camera settings. They will give you amazingly good results and images without doing any color grading gymnastics. Dlog is a format designed specifically for those who want to perform serious color grading, but if you initially record in dlog, the images will be "flat" color-wise. You won't be color-grading for quite some time, if ever.
As an example, let me paste a link of a video that I pasted together of my local town. It was shot with no color grading, and before I tamed the gimble and pan settings. It was also cut short at the end when flying critters attacked my drone. It's also too long, and was rendered in 1028 resolution (-It was shot in ultra HD, but reduced so that it would play on older computers). -Lots of mistakes (-I used the wrong kind of dissolves), but I use it as an example of what you can do without being proficient.
Amazon Drive
To edit, I used a video program called Resolve 15 Beta. It's a free download, and can do virtually everything that the pay programs do. It's also well-supported on YouTube, so you can view how-to clips there. I have it installed on a laptop with 4 GB memory, and it runs adequately. The program will be overwhelming at first, but when you begin to break it down into pieces (-Resolve lets you do that) it'll slowly come together. The gurus on YouTube talk too much lingo at first, and it took me lots of practice to understand what they were rattling off.
Oh, and another good program to just view your videos is VLC Media player. It's also free.
