For Video, on PC, consider Divinci (free version) and or Premier Pro, (not free) I would recommend the subscription model, for Photoshop and Premier, should be 19.99 a month.
First and foremost, go to youtube and search for video editing (drones or any video).
As a still photographer for over 40 years, and digital users since 1999, I can assure you Video editing is a totally different experience.
Also, you should also try using the "free" video editing that DJIGO4 offers. You can make pretty nice videos with this toolset, for a start. DJIgo4 does most of the work, you just pick the clips you want. Not a bad starting place.
