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.

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

CinemaDNG is not always compressed. I have a BlackMagic camera that records uncompressed CinemaDNG. Also, DJI has gotten around some of this by putting the recorder in the body of the drone, making it technically not part of the camera.

However, the oft-repeated claim that Red's patent applies only to internal raw recording does not hold up when you consider that Apple and Atomos have to pay extortion for ProRes Raw, which is used in EXTERNAL recorders.

It's also only available bundled with ProRes, although it's almost certain there's also some backroom RED RAW-racket deal going on too.

Well, that's DJI's decision.

Except that they do offer exactly that. No need to be so condescending. https://www.dji.com/lightcut

There's certainly no requirement to use that (it's literally a separate app from the DJIFly app you use the control the drone), and I do know as I fly a DJI mini drone. What's worse is that I don't think it actually works how you've assumed. The drone has no internet connection itself, the software is instead pulling the files down over wifi, which is something the standard software supports if the drone is close eno…

Holy irony man

Yes, based on my experience with the device I can extrapolate how that software could work. What experience did you base your assertions on? Nothing at all? Right.

I don't know enough to offer any real sources, but I'll share that I've found ChatGPT very useful for learning stuff like this - really solidly documented and established science/engineering. I asked* "When making a wireless transmission what is the signal loss at 20km for 2.4Ghz?" and it gave an excellent explanation of free space path loss, stepped through the calculations, and gave the correct answer. I've had it…

> but I'll share that I've found ChatGPT very useful for learning stuff like this I get your point, but no way I use ChatGPT. Other than all the ideological issues I have with it, I just can't trust it. > and gave the correct answer. Are you saying that because you believe it did, or because you already knew the answer? I don't trust ChatGPT, so I don't want to learn anything it says. And I don't need it for stuff I…

Because there are other ways (simple Google search, asking an EE friend, etc) of validating the answer. Often I'm looking to learn a concept so it isn't like I'm using it to solve a bunch of things. Just validate my learning. It is easily as good as having one of my EE friends explain the concept to me.

They're cloud based, aren't they? So regardless of what they're doing with the data, it's true that they're (figuratively) beaming it back, although parent is admittedly implying more. I accept that chinese authorities generally have access to anything they want to in the country, so I would buy that they have access to drone data.

They're not cloud based as far as I would define it. I have one and fly mostly on areas where there is no internet signal. The drone beams back video to your phone and unless you're syncing the cache videos with their cloud nothing its stored other than flight meta data. You can avoid even that by using a totally offline controller/phone.

How does the drone communicate with the phone?

I got all excited thinking of the potential of keeping this at the bottom of someone's pack given it's low weight, until I remembered how much I despise people flying drones on top of my head whenever I'm out in the outdoors, looking for a peaceful place to connect with nature.

Exactly how I feel. For me, I think the best use case for drones, if I were to get one someday, is for shooting sports/events where the prop noise would be drowned out by an already noisy environment. Like motocross, or a basketball game, or a car meet. There's no way I'm taking out a buzzy drone when out on a quiet hike or at a typical campground. Just kills the calmness.

You’re not legally allowed to fly a drone over people without authorization.

DJI is fully compliant with China's policy of civil-military fusion. Anyone flying anywhere sensitive should not use them. They're beaming back home whatever they want, and China is using both tech and data to give an asymmetric advantage to allies like Russia in the Ukraine war.

How do Ukrainian operators avoid exposing their own positions? Do they install custom firmware on their drone?

jailbreaks.

If I claim to see the drone even if it's very far away, can anyone dispute that?

Hand me the controls and tell me if I'm steering it left, right, up, or down. If you can, congrats! You can see it. If not...

Oh damn, when I took my eye off the drone I lost it!

Yup. They could not get competitive so they had some politicos pimping for them and can now feed on taxpayer's money.

The empire is collapsing so might as well rip the last remaining scraps of wealth off the walls before it goes all belly up. I would do the same if I were in their position.

The US isn't an empire and it is not collapsing... Don't believe everything you hear on social media.
