It's super fun to just go out and fly but want to get better at actually doing some video stuff. My videos now look like I'm having a seizure.
Like they’re shaky? Mavic air video should very smooth with minimal effort. Unless you are jerking the controls around. You want to barely touch the controls when you are panning, changing direction, etc. also check out autonomous flight modes like “point of interest” “waypoints” “follow me” etc. The drone will basically fly itself based on how you set it up. That will take your shaky seizure hands out of the equation.
Lastly, if you want good looking drone video, it’s all about time of day. Within an hour or 2 of sunrise and sunset. A lot of dynamic range during these times which, with a little editing in post, can make your drone footage look amazing with bright brights and dark darks. Flying in bright sun or solid gray clouds in the middle of the day will never produce a great image no matter your flying expertise.
Also lastly, if you want really great images/video you’ll need some way to edit/color correct them. I use Adobe Lightroom for photos and adobe premiere pro or after effects for video. There are a lot of cheap (maybe some free?) options out there for editing/color correction.
