Streaming 1080p/60fps up to 20km wirelessly is mind boggling to me. What kind of tech is used to make that happen? seems like it'd require a lot of power.

Transmitting long distances lives on a kind of spectrum. On the one end you have MOAR PWER and on the other end you have signals analysis and robust codecs (? I'm not sure "codec" is right. Maybe encoding? Can someone answer this?) that allow for lost information. The signals analysis will clean the incoming signal and the codec/encoding will allow for robust recreation of the captured data. Most wireless transmissio…

I've had the original Mini since it came out. Other than damaging a prop from it hitting a blade of grass on landing it is in perfect shape. Yes, they are so fragile I landed very smoothly in the grass and soft grass is enough to damage the props! I don't fly it as much as I used to. These new ones are certainly an engineering marvel with how much they have added and still kept it under 249g. The big one to me though…

Another gripe about DJI for video use is that they rip you off for a "license" to use CinemaDNG... which is an open, license-free codec.

Perhaps but I fly my Mini 2 regularly, and people have a hard time finding it in the sky even when I point it out to them at 100ft. At 200ft it might as well not exist. They are so small and light, they just don't put out the dBs like bigger drones.

Being able to spot a small white object in the sky and hearing it are very different things. I put drone operators on the same level as those who hike with speakers blaring. No one is being hurt, no laws being broken. Just inconsiderate considering a large part of the experience for most in nature is the serenity.

Isn’t this because they have to pay Red for their ridiculous patent of compressed raw video?

Light drones are great, but how far away are we from quiet consumer drones? I'd love to not have every hike ruined by some wannabe videographer.

Should't be too far away, the commercial drones of Zipline are supposed to be super quiet. Here is video demonstrating the tech: https://youtu.be/DOWDNBu9DkU?si=_x9vSAygUSHq4ZQw&t=832
