you know you're a hardcore tech reviewer when DJI hires you for their own testing & collecting data, nice one!
Every camera manufacturer should start doing this, so we can finally get accurate dynamic range data on all cameras.
@@MarkusFinholtthey. Have accurate dynamic range data. But they are purposely over hyping things. Because they are not just telling you the useable dynamic range
The man coming out with a Ronin 4D test and not showing and crazy gimbal action footage, only test charts. Legend.
I mean it's right in the intro "he's craazzy" haha
Your measurement oriented reviews are one of a kind. You explain this esoteric stuff very clearly, even for a less than expert. I’m surprised you haven’t reviewed Sony’s new A7 with true global shutter. I’m really looking forward to that review. A review of the Hasselblad’s X2D, although stills only, would be interesting due to it’s gaining reputation for dynamic range and ultra-calibrated color accuracy, which nobody else measures as well as you do. Thanks for all your great work! Cheers!
The a9iii isn't available for review yet
Well, it was A9III with global shutter, not A7. And as mentioned above, it's not released yet. And won't be for few more months. All those reviews around web were made on pre-production cameras. I don't think that any was send, all were given to reviewers for some time at press conferences.
I recently purchased the Ronin 4D 6K and, as a solo operator, I absolutely love it. I'm grabbing a coffee and watching this NOW!
I think the extra magenta in the color test was from your wall painted in "Gerald's Hue"😂😂
My favorite type of video from you. Super nerdy level of detail. Love it.
I was super surprised when I first got to play around with the 4D 6k, not just because it was so easy to use and you can get dolly-like shots with minimal effort, but it almost looked like the camera was creating light out if nowhere while looking at a city scape at night. Love it
As always, excellent video! 🙌🏾
Very useful video, cheers Gerald.
Great job on the video Gerald! Thanks for making it.
Awesome Review Gerald, glad you did the DR test, still need to get myself a Z21 to test those things. Nice discovery about the noise. Thanks again
Gerald knows best!! Amazing breakdown as always!
Thank you for your work.
Be lucky stay safe.
Technology is bonkers! Love the content Gerald, thank you!
Thanks for this, Gerald. EXCELLENT and clearly demonstrates the value proposition and tradeoffs! Thank you!
I'm a simple man, I see Gerald Undone, I click. Loved your content ever since I started watching in 2018, cheers from a fellow creator from Québec!
Always appreciate the work you put into these objective tests. Kudos. I'd like to humbly suggest that you add testing actual resolving power (lpp detail, not pixels) to your test suite. A higher sensor resolution does not always equal more real detail (For example the 8K Sony A1 resolves more real detail than the Ursa Mini 12K) so measurements from an actual resolution chart would be very helpful. To keep a level playing field, you could always use the same super sharp EF lens (Sigma cine primes are sharper than any sensor can resolve) adapted to every other mount.
I've missed these super nerdy moments from your reviews! More nerdy please!
Great presentation of information!
It's so refreshing to see a brand reach out to a trustworthy third party to do scientific tests. Makes me trust DJI more.
Always a pleasure Gerald. Excellent. Yes I want one. No I don't need it.
Bro SOLID breakdown!! So interesting. Also, like we talked about before, other companies need to give us the option of quality or performance!!!
Thank U, Gerald.
Mr. Undone at his best! The chances of me ever owning a DJI 4D are zero but I still enjoy hearing the details. Love what you do, Sir.
Thanks for sharing it ✌️
Hey Gerald, thanks for doing this, fantastic video. My main complaint with the 6k version when I used it on a couple projects was the forced aspect ratio and crop changes with frame rate. i.e., going from 4k/24p to 4k/120p required either a switch from 16:9 to 2.4:1 and/or a switch from full-frame to S35 crop. It made it a nightmare for composing shots and it was a nightmare for my editor. Have they changed that for this new 8K iteration? It appears you can shoot basically any combination of resolution and frame rate at any aspect and full frame?
Mostly yes, there are some modes that are cropped, but you can shoot FF 4K 120p and even up to FF 8K 60p
Would be dope to see a review of the ZCAM F6 Pro with your level of analysis. Great video
I would never consider getting this camera but enjoyed the review.
I love your contents.
Can you make a video on how you analyze dynamic range in the software and how you measure rolling shutter?
Just got off my first job with the 4d, which this was out a week ago!
Gerald, please review the GVM Pro SD300B Bi-Color LED Monolight. I'm curious if they are worth the buy over the godox vl300 ii.
At a shoot right now with my Ronin 6k. Never going back to any other camera. Love it!
Hello Gerald. Regarding putting the 8k footage on a 4k timeline. What algorithm are you using to do the downscaling? How much does that affect the resulting calculated Dynamic Range?
Thanks!
Over sampling does not affect dynamic range, but it effectively reduce noise
@@lucasvivante8988reducing noise means more of your image is usable, meaning more dynamic range if their are details in that noise floor
@@howardtownsend2574 that's not whay dynamic range is... If so using denoise algorithm would increase Dr. It's about if information is here or not
The 8k Gimbal has an OLPF included. Check the filter 4P34. I installed it manually on my 6k.
thats cool!
Thanks for doing the awesome work Gerald!
We need more aerodynamic lenses.
I think that the magenta shift in the 4d just gives approval of the Geralds Tint😂
I'm curious about the difference in dynamic range between ProRes HQ and RAW, even though ProRes doesnt compress as bad as avi or mp4 it still would loose some data. But overall the highlight roll off and rolling shutter have been improved.
There is none. The D-LOG curve contains all of the dynamic range the sensor can capture, no matter the codec. There may be reasons to shoot raw, DR is not one of them.
Usually you get worse result with raw codec，because raw has no denoise.
What is the dynamic range for dynamic range expansion off and noise reduction turned all the way down? 11.5 stops?
So what would negative noise reduction be exactly? Is zero still noise reduction? The default?
Can someone confirm! Is it impossible to turn off Dynamic Range Expansion when in 4K downsample? I would have been mainly interested in that mode - 4K downsample in 24fps with the standard (fast) readout.
Finally, a camera company has twigged that it’s probably a good idea to get Gerald to check out your new product *before* releasing it. About bloody time! 😂
this is a camera that always intrigued me as I always fly on a gimbal, but won't work for 20% of my work, where I use a 70-200 on a gimbal or a remotely controlled zoom lens on a camera car :C guess I should keep the FX3s
Forgive me if you mentioned this... I don't remember if you might have but, Would any of these specifications been different with other brand lens choices?
Is anyone else reminded of Jonny Five when looking at the Ronin 4D?
I always wanted the DJI Ronin ever since your body Josh Yeo did a review. Being retired NOT HAPPENING. But still think it a very neat product. How big a lens can you put on that gimbal? my Tamron 35-150 is heavy!
Pls bring back the swirly outro with the guitar line in the background, it's my favorite
Great content as always. PS, I know you’ve moved beyond m43 but would love to see you test the g9ii
The 6k definitely suffers from moire/fine detail artefacts as it doesn't have an OLPF fitted. How does that factor in?
If the 6k windows in to get 4k when in s35 mode, does that mean the s35 4k mode on the 8k sensor is oversampled?
I have no idea what Gerald is talking about but let's fucking go a new video.
Does the 4k 120 oversample from 8k?
Unreal, been waiting for this, I hope DJI bring more power zoom lens out also
This is what I love about your channel man. When I use cameras I can see the difference and figure out what they’re doing.. but it’s like a caveman starting fire. And then I watch your video on the same camera and it’s like a flying car passing over my fire 😂. Great video 🪶⚡️🤘🏽
It's insane that we are still NOWHERE NEAR the dynamic range or equivalent ISO of the human eye lol. I believe it's something like 20 stops of range, which is massive. The amount of optics processing that our eyes do is incredible when you really think about it.
Your eyes basically auto expose for whatever they're looking at though, so it can cheat a bit to pump up the imatest score.
Alexa 35 probably has enough dynamic range for it to not be a complaint though
@@thatcherfreeman I was gonna say, I think the new Alexa Mini LF comes the closest. And even IT isn't especially great in certain situations.
@@spdcrzy The Alexa 35 has a couple extra stops over the LF, it's at a point where flaring in your lenses is likely to be the bottleneck before the sensor, it's kinda crazy
The new Alexa 35 is up at 17 stops, which is absolutely insane!@@spdcrzy
the data is sent to the brain for instant processing. It is Iike taking an image and sending it
to lightroom for instant processing, labelling and cataloguing so it can be retrieved and compared to other images when needed. and this millions of times every second.
Please share how does it feel being mentioned by legend Philip Bloom in a video.
Hope they update the Inspire 3 with DR expansion toggle 👍👍
Nice, i like it, need like this but in hasselblad X2D if u have it already let me know to watched, thanks.
Is the gimbal good enough for DRE?
I am LOVING what DJI are doing at the moment. Innovating the sh*t out of the category.
My Christmas gift to myself!! 🎄🎁 “We got a lot of K” 😭😂🤣
Some of your videos fly over my radar but you do it with intelligent class so I keep coming back: compare that to sitting down and studying for a part 107 test. I’d much rather watch your videos and skip having commercial drone footage and put my camera on a long pole!😂
Never I have been this early to a video!!!
I would love this camera for the 4th axis gimbal (my ninja walking is rubbish) and I really don't care about 8K, or even 6K - most corporate clients don't want to deal with those file sizes either. It would be good if they just produced a 4-axis gimbal you could put a camera on yourself - that would definitely get my interest!
4 axis gimbal for a camera would be huge, since most cameras are larger and heavier than the ronin 4d gimbal head.
It's nice to see the price, which the 8k gimble only is under 3000$, as a 6k user i can't refuse that price tag.
not surprised when i found out the test chart can cost as much as the 4d ronin itself
Subject idea: How do a pair of cameras compliment each other? So like many serious weekend photographers or maybe pros we/you are covering a range of capability for fun or work. Which pair of cameras keeps you light and capable in producing fun or professional content with ease and quality? Big question yes, but in the end, we all want to have fun. You know many of us will get two camera bodies, share your ideas. Consider getting up and going to location and back to uploading a fun video with photos or slide show.
I need help: The Ronin 4D has been released 2 years ago, both a 4D 6K and a 4D 8K version. Why is there all this buzz about a new 4D 8K camera? I don't understand.
The 8K version was announced back then, but wasn't released until now.
oh wait fr? didn't know that, ty@@geraldundone
Where is the a9iii Review?
Really interested in how DJI was able to add ProRes Raw internally with Reds RAW pattern.
Is it partially debrayed ?
I loved it when I saw they had released the adapter to use our Sony lenses on the gimbal .. if only it was digital and you could control the aperture and AF.. the 24 1.4 GM would be the kill upgrade on the inspire 3.. (as if lowlight wasn’t amazing already at 2.8 )
The DJI e-mount adapter for the X9 IS electronic and does allow for focus and iris controll. The 24mm GM is even on their supported lens list.
@@TechnoBabble I realized that later.. makes me want it more haha..
You can control the AF and aperture…
👍
I’d really love to see a sensor come out (no specifically from DJI) that gives a TRUE 15+ stops of clean dynamic range. It would look glorious!
The Arri Alexa 35 (ALEV 4) is what you are looking for.
@@doug7131lol the Venice 2 has great dynamic range
DJI, please! Make a boxed cinema camera, without the gimbal, for the Zenmuse X9-8K ❤
Sigh... every-time I think about a piece of gear, you make a vid about it.
Is there a reason why we dont have a review from the a9iii Gerald Undone style? I need that 😁
As someone who works next to the DP on set and has used this camera many times on feature films in 2022...it's not good at all. For a myriad of reasons...but for RUclipsrs like Gerald..it's a perfect camera.
Please explain your statement. I would like to know what makes it unusable and/or “not good at all”
I had the 6K version and sold it. I shoot wedding and a lot of indoor events. One thing I kept running into was the flickering. Great concept but I feel like it’s not complete yet.
There's a setting to do 180 degree or 179 degree along with a couple other settings to combat flickering. Or you could get the OLPF filter installed as well if shooting a lot of screens.
Is it better to edit 4k footage on a 4k timeline and export to 1080 or is it better to edit 4k footage on a 1080 timeline end export to 1080?
Its an interesting camera to be sure. Flexibility is always going to be desired. I do find it interesting that DJI never lets you disable noise reduction. Several other manufacturers as well. So, we never actually get to find out what the sensor is truly capable of, just close. -2 is not off. You always have to ask why. A guess? The sensor is noisiser than most people would accept with limited knowledge about how cameras actually work. NR is part of a signal chain. Doesn’t matter if its in pre or post. Its almost always there. People assume that a Sony sensor is cleaner than brand X. But the Sony would be running NR in camera and brand X has none in camera. Its a disconnect people have. I honestly wish all manufacturers would allow NR to be disabled. But, its all about marketing.
I think because pure data noise is really noisy. Every manufacturer have to code algorithm to intepret the data coming from sensor in the first place. Even simpler example is raw photo, it's not really rawest form, just base manufacturer intepretation before they apply some more polishing to jpeg/heif. You don't want people returning the product because they mistook noise with artifacts
I'd say the analogy is like frozen food or ready made sauce rather than just the ingredients in the initial form with skin, dirt, and all imperfection still intacts.
@@trym2121 Gopro lets you turn the noise reduction completely off, and it's actually useable without noise reduction as long as its exposed to the right.
Shooting ProRes RAW on these newer cameras is the only way I've seen to completely bypass noise reduction.
I own an S5 and S5iiX, shooting BRAW, the BMVA applies a very light spatial denoise pass to the image. ProRes RAW, absolutely no noise. I still much prefer a perfectly untouched image as the sensor's pure detail is captured. Expose it high, bring it down in post, noise looks really pleasing anyways if you use the sensor properly.
Cameras like Fuji have spatial chroma NR cranked to an INSANE level, if you ever get some F-log footage, look at the Cr and Cb channels, blurred into an oil painting. Just give us the option to disable it.
@@alihammad6318 Interesting point. Didn’t I see Gerald set the noise reduction at -2 on proresraw? And if so, that would mean they are baking in noise reduction?
@@ScottBalkum if it's true raw, like prores RAW, the signal is taken straight from the sensor in its raw Bayer pattern and dumped. The computer debayers and does all the processing. Which means it gets to skip all the processing.
I don't have any experience with these DJI cameras so I cannot say anything on that but likely have some sort of spatial denoise filter running, they just turn it down. Pure, completely unprocessed sensor data is quite noisy even with good light but looks the best imo.
Where can i get for free?
is it Netflix Approved?
Ah what the hell. $13k I’ll go ahead and order 6.
I was hoping to see the 4D gimbal technology to come down to cheaper lines over time and not go up in price/resolution. 😆
Oh there's no intro music or random quote in this video
what would me the sensor speed at 8k 60p ? PS: if they add a global shutter in the future its end game!
It looks like the SONY A1 sensor.
Gerald, the Z9 4K 120FPS readout speed is 5ms ... Just saying... Source : ruclips.net/video/L6wYejSaO4M/видео.html
"I'm Gerald Undone, and my focus breathing is called meditation."
what a real shame that DJI isn't offering a Ronin-4D-Air, so we can reuse the 9k-Zenmuse air from our Inspire3 .....
It's amazing that the Sony zv e 1 and a7s iii can get 12.9 usable dynamic range stops with better rolling shutter. To match the extra 8k resolution you can just use the Gigapixel AI to upscale to 8k. What do you say Gerald?😅
Upscaling is never the same as actually capturing more detail in the first place. The better comparison is the A1, which matches the readout speed and resolution of the X9 8k while having the same or slightly better DR than the A7S III/FX3.
@@TechnoBabble but is there any visual difference that regular people or even pros can notice after it's exported? I seriously wonder 🤔
@@paulkunal5586 Not if you're just shooting in 8k and not doing anything in post with it.
The main reason to shoot high resolutions like 6k and 8k is the ability to nearly losslessly reframe and digitally stabilize footage for 2k and 4k delivery.
FINALLY FIRST!
great video, still need to watch it fully tho.
Love to see that DJI keeps pushing his Ronin4D and keeping the body upgradable.
*Second. I beat you
🏆
why don't all cameras have a global shutter?
Gerald, random, I know, but your sweatshirts look really nice, where are they from? Cheers! I watch for more than staring at your clothing (promise)
DJI should make a 4D gimbal for my fx30 instead of trying to rope me into a super expensive camera system.
Thumbnail looked like Midjourney 😅
Hi
Only $13,000 and comes with a 17 to 28mm T3 DJI DL mount lens. Get at least 2 of them!
