I am a little jealous of that Mavic 3 pro. The weather here has been pretty crappy for the past few weeks, but there is usually sometime during the day that I can get a drone up.
I have 5 batteries including a couple extra capacity batteries for the Mini 4 Pro and the Mini 3. That usually gives me more than enough capacity to spend the day getting some good video and pictures.
My first drone is a BWine that is fun but has an oddball chipset so video does not render very well.
I was once having some difficulty getting video to render properly. I scoured the forums and could not find much helpful advice. I started using a conversion program that made it possible to use with it with my preferred nonlinear editor at that time. It turned out that Microsoft did not include the proper CODEC with Windows 10. They were holding people up for a $.99 add on from the Microsoft Store... This was totally cheesy and their part.
I would not have minded paying the $.99 but I was irritated that it took quite a bit of troubleshooting to figure out the source of the problem. I am guessing that there is probably a solution for your BWine, but with your Mavic 3 pro it would probably be a waste of time to figure out.
I have several drones that take fairly good video, I also have a tiny camera and transmitter that I can attach to almost any drone. But none of my setups have gimbals that are as good as what are found in most DJI drones.
The Mavic is one beefy little machine.
I bought it as investment to try to get paying gigs.
The codec thing on the Bwine is common thing as I found.
I have to say it’s got a lot of functionality and fast.
