The colour artifacts are due to the Quad-Bayer sensor design and could only be improved with better RAW debayering algorithms in post. This is not a bug but a hardware characteristic and I wouldn't expect this to be fixable in a firmware update. I shoot in 50MP exclusively except for Pano mode...

I don't have the Mavic 2 Pro. The exposure behaviours we see only seem to start happening since around the Mini 3 Pro. To confirm, you only need to watch the highlights when you toggle Auto ISO. On recent drones the recovered highlights are usually obvious. On the Air 3S, there is also a...

Any particular point in the video you'd want to refer to?. Edit: found it (~7:20), this aligns with my observation, thanks. Many modern cameras (particularly phones) employ the same trick. They seem to be based on/inspired by the Dual Conversion Gain technology from OmniVision.

Yes, Auto ISO mode applies some HDR-style post-processing to the video feed which isn't done if the same ISO/shutter speed are set manually. It's easy to see for yourself by toggling it. You should observe an immediate difference in the highlights rendered. This is a known fact about the Neo...

In recent history, DJI's drones have always been favouring high ISO and high shutter speed rather than sticking to as low ISO as possible and lowering the shutter speed to compensate. I'd always found that puzzling. The recommendation that most people give is to disregard the drone's poor...

I don't have the Mavic 2 but it should be found in Settings->Battery section in the DJI Go app. Yes, 40-60% is the ideal charge percentage between a semi-ready to go battery and minimum loss of capacity over time. At 40% you can still do a quick 5 minutes flight for scouting even on the spur of...

Lithium-based batteries can be stored at 100% charge for a short period but you will observe reduced capacity due to the build-up of internal resistance over time. Depending on the environment temperature you might lose as much as 20% capacity per year at 25C. We can probably reason that...

You are mistaking perspective with field of view (please do some research on this). Yes, cropping this image to 1/4 of its original dimension will provide exactly the same field of view as zooming in by 2x.

I found that with Goggles firmware 1000 and Mavic firmware 700 the Head Tracking functions no longer works**. Could anyone please check/confirm?. **I have not had time to test flight it to see if it only doesn't work whilst stationary.

I can confirm that this issue has been fixed. The HDMI video is displayed to all edges of the screen with no scaling.

I believe you were referring to this thread: How to: avoid GEO System-induced forced landing and crashes :) . I think the set of coincidences can be reduced to: * A dynamic NFZ is added during flight (such as from the result of a TFR), or * The aircraft has taken off before the GEO System has...

The tilting is not very smooth to me, but the amount of tilt otherwise looks normal. Due to the inherent noise in the gyroscope & accelerometer, some amount of integration time is required which makes the gimbal's correction lags behind the actual camera's tilt. A shorter integration time makes...

It's not a physical limitation of the gimbal. The gimbal uses a pair of gyroscope & accelerometer to know its orientation in space. I expect that all current consumer-grade gyroscopes will behave the same. What you've been seeing is called 'bias' as the gyroscope's output is inherently noisy...

I do agree that the 8-bit colour depth doesn't make it very malleable in post, not to mention that not everyone is keen on doing so. That said, my post does give a few (subjective) reasons why I went with 0 colour and 0 contrast which is to not make the 8-bit depth worse than it already is. Some...

I've done a fair amount of research on the best video settings for the Mavic and concluded that 2.7K@30fps D-Log +1, 0, 0 is best in terms of sharpness. You can find proof of it in my post: Mavic Pro: why DJI doesn't fix this huge flickering/compression problem? . There is some flickering issue...
