![Mavic 2 Pro Sharpest Settings & Best Focus Method [4K]](/img/1.gif)
Thank you for your explanation Re: the Hasselblad sensor. Your the first person I’ve come across that has made it easy for me to understand. So I don’t think that DJI is ripping us off.
Thanks I really appreciate it.
This is the best video about this subject I've seen so far and probably the only one with all the right info. So thanks very much! I know now I'll use FULL FOV for most "cinematic" and creative videos but probably the HQ setting for eg. roof inspection. Correct me if I'm wrong please.
I am wondering how the heck you know this stuff, I guessing you didn’t have a RUclips video to watch. Brilliant video
Thanks :).
Thanks for the fantastic explanation of what goes on “under the hood” I am not particularly technical but understood it first time round and would happily watch more if you’re thinking of making them. Take care and catch you later. Peter
peter hughes Thanks :)
Always enjoy the technical aspects explained simply and the great graphics. Thanks
james R. Thanks :)
Hopefully this will reduce some of the hysteria over Mavic 2Pro. Although if I'm not mistaken the P4P uses the same processor, produces a better 4K video, and thus I'm guessing that the processor (which is the same in the P4P and the Mavic 2pro) can down scale by doing sampling. My guess it that, like some of the Sony pocket cameras with the same sensor, it's an issue with overheating that caused DJI to use another method to down scale the full FOV mode in the Mavic 2pro.
@Lon Denard, yes, there's quite a bit of hysteria going about. And I've just read a note someone recieved from dji support that says that in fact they don't do line skipping or pixel binning, but that the image processor in the P4P and the M2P are not the same, and that is why the images are not equal. They say the M2P does do full sensor sub sampling. The M2P is still a major upgrade from the M1P, and the best drone of its size currently, so there's really not much room to complain.
Appreciate these details as I now have a good understanding which will help me decide how to shoot with the M2P based on my needs...Thank you
Donald Race thanks.
Outstanding info. I thought I knew all about this stuff and you still taught me a few new things. Excellent technical data that is perfect for a geek like me.
Absolutely a perfect explanation.
Interesting details...thanks for explanation 👍🏻
Having a pixel binning (side-by-side/above-and-below averaging) option would still be great for colour range and noise reduction - even through the output resolution would be 2772 by 1847. Given that its CMOS sensor, boosting the gain would mean better signal to noise for low light capture too. To get that extra available light gathering capability from the camera one has to use the 'hyperlapse' (RAW) option for moving images.
Fantastic explanation! Thank you!
Your content is simply the best, no bullshit and educational.. I really appreciate your channel and hope you are able to build it up !! You are more deserving that half of the twats that get on here spouting the same bullshit..
Thanks for the video. Be careful, the FOV of 55 and 75 degrees are DIAGONAL values (and not horizontal values, as shown on the diagrams).
regards,
Andre
Great spot thanks for the comment
Bit depth has a much larger role in sampling significantly more data from thicker colour information.
Wow. Someone who knows what they are talking about. So much misinformation out there on this topic. Thank you. One questions I have though, is there a point as it gets darker, that using the full sensor outweighs the negatives of the lower quality down sampling sense less noise gets introduced?
Excellent explanation! A couple of questions. 1. Can you use 10bit h265 in either FOV or HQ modes? 2. Can you do a comparison with the MP-2 vs Phantom Pro 2.0 image quality. I see some side by side comparisons and they're supposed to have the 'same' 1" sony sensor however, the Phantom's video images, to my eye, look noticeably superior! Can you explain why this might be the case? Thanks!
thanks bro
so, big question is, how do they do it on p4p, they could use same processor and call it day. i really doubt it makes such big difference in cots etc. they attentionally downgrade video in m2p (optical resolution wise in full fov 4k mode), to keep phantom series at their place.
Nice 👍 !!
what is the mavic 2 pro's camera focal length in comparison to full frame lens in 4K and 4K HQ?
Thanks, I didn't know using the full 20MP sensor will give a poorer video.
Crazy.
It's Only Me not always as I said it’s down to how you process it, in things like the Panasonic GH5 and all the larger mirrorless cameras that do proper sampling it can bring some massive advantages but on those they have massive amounts of processing and in-house hardware to do this, DJI are at the whim of Ambarella and while the M2 uses the H3 we believe it’s still got its limits.
Do you know what the pixel sizes are for the mavic pro and the mavic 2 pro?
Fantastic explanation. Thank you. Would mind say if you know where the Crystalsky update is for the Mavic 2? Thanks 🙏
harvey19750 currently I don’t know it’s coming but no time scale given sadly.
Thanks for the explanation. It's a pity that not the full 1" sensor can be properly utilized while filming video. Looks like it's the processor to blame because it cannot super sample and downscale in a lossless way. BTW, in the HQ mode does it only corp the image, or does the equivalent focal length change as well?
When you use a crop of the sensor you change the focal length, that's why the field of views are different in the two different modes.
Would it require less processing power to do a 1:1 output of 5k video?
Maybe dji should just let us film in either 4k or 5k...
Yes much better but as all can See they are crippling down the sensor reading half of 4k res in fov mode and leaving us with a narrow fov on normale 4k readout
Great explanation!!! But what about low light conditions? When I am right you should use the entire sensor, Or?
Savier Laumen technically yea larger sensors would help but again it’s down to how it’s processed, they can do some cleaver things with larger sensor data though with dynamic range like change the gain on each line to increase overall but again there are downsides and upsides to everything. The biggest issue is the onboard processing and while the M2 appears to use the H3 from Anbarella this is massively limited compared to what you have in cameras like the Panasonic GH5
Oké, how do they do it on the Inspire2?
Hi Mad , all very clear, thanks for the explanation.....
but I do not understand ... why in HQ mode the image is zoomed ?? this is not clear to me and I do not understand, if in HQ you use the central portion of the sensor, in order to get a native 4K I think you should leave the same size, in your example (at the minute 6'40 ") the image does not it is enlarged, in reality in HQ a zoom is performed of the image that inevitably technically modifies the image and does not create a condition for a correct comparison between FULL and HQ.
Do you know why this happens?
Thank you
the lens is a fixed. there is no way to not change the field of view if cropping the image at the sensor.
This is a great explanation of a known problem. Thank you for taking the time to explain this in great detail with great graphics. But it is STILL a problem I am not happy with the field of view required to get full quality on this drone.
And full quality still suffers a bit from sharpness, 4K seems more akin to 2.7 K when viewed side by side to the Zoom, although perhaps that is solved by sharpness settings. I would rather have seen them adjust the lens to get a true HQ 4k Crop with a better field of view, and lose the full sensor FOV mode entirely if necessary, since to me, all the extra beauty, dynamic range, colors, and post processing capability, is worthless without the Field of view. and the sharpness that I would expect from this PRO line.
I love the explanation, but it still doesn't solve the problem. Nice drone any way you slice it, but because I need FOV AND sharpness, I will probably have to go with the Zoom. I am losing very little at the end of the day, since I can get the videos I want without the compromises I would have to make. Trading dynamic range for sharpness and a more creative field of view. I hate that there is no adjustable aperature on the zoom tho. Maybe I will just wait to see what they come up with next. Also question, since I don't have this drone. You implied at the beginning that this is GREAT for photos, less great for video. Do I take this to mean that there are full sensor size resolution settings on the photo capture? And they are super sharp, i.e. How good is that lens, and between the lens and the full use of the sensor, what is the result? Databyter
"h" = "eych" ;)
I would of happily paid more for the m2p with a faster processor to unlock the full capability of that 1” sensor , I guess they will just add it to anther drone instead
The faster processor is on the P4P, that's how they can justify the higher cost of the P4P.
It would cost more and use more power (less battery life)
ironically,....the full width FOV wide readout (pixel binned) produces the worst quality. However, the sensor crop mode that uses a FRACTION of the sensor (1:1 so called "HQ")...gives you it's best quality. LOL,...how backwards is that? Pixel binning and line skipping are evil!! ;-)
Cliff Totten but your video (and others promotion of it) helped to create a false hysteria that somehow downsampling the sensor to achieve 4K is somehow DJI cheating people, which it’s not, it’s how one achieves 4K video from a sensor. So now we all get to read the never ending “DJI ISNT USING THE FULL SENSOR, BUY THE AUTEL EVO” for the next few months. Thanks cliff 😭😭😂😂🤘🤘
@@flyguy8787 - So there are different ways to read a 14mp photosite count and scale it down to 4k. Line skipping and pixel binning are only two. (The two crude ways of doing it) The more modern way is to sample ALL the photosites in a 16x9 crop WITHOUT binning them (averaging clusters together) and creating a complete 14mp image FIRST and THEN scaling that finished image down to 4k. This is what Sony and Panasonic do today as well as the Phantom 4 Pro and Inspire 2 do too. Pixel cluster averaging (pixel binning/subsampling) actually CREATES "gaps" in its image while full pixel readout helps to "fill in" gaps during the RGGB deBayer process. Ultimately, full pixel readout and scaling down is far more sophisticated than pixel binning raw sensor data before the image is assembled. Pixel binning and line skipping was very popular in the earlyvdays of DSLR HD video recording but we a long past that in 2018. (Unless DJI was forced into it by a problem they wont tell us about)
Cliff Totten oh for sure man, I’m not trying to attack you personally or anything, I meant it more as light hearted poke. super bowl history 4 lyfe 🤘🤘😃😃
It's all good!
