  1. I have read Canon's h265 4:2:2 is even harder than h265 4:2:0... but there are people still complaining with modern processors: https://www.reddit.com/r/Dell/comments/hbs81k/xps_15_9500_i7_10875_cant_edit_4k_h265_video/ In doubt what's the best? A Hexa-core i7-9750H or Xeon E-2276M with the Quadro RTX 5000 16GB VRAM? Or Octa-core i7-10875H with a RTX 2080 Max-Q 8GB VRAM? Or yet the Octa-Core Ryzen 7 3700X but with the RTX 2070 8GB VRAM? https://cpu.userbenchmark.com/Compare/Intel-Core-i7-9750H-vs-Intel-Core-i7-10875H/m766364vsm1111393 https://cpu.userbenchmark.com/Compare/Intel-Xeon-E-2276M-vs-AMD-Ryzen-7-3700X/m785884vs4043 https://cpu.userbenchmark.com/Compare/AMD-Ryzen-7-3700X-vs-Intel-Core-i7-10875H/4043vsm1111393 https://gpu.userbenchmark.com/Compare/Nvidia-RTX-2080-Mobile-Max-Q-vs-Nvidia-Quadro-RTX-5000/m704710vsm712800 https://gpu.userbenchmark.com/Compare/Nvidia-RTX-2080-Mobile-Max-Q-vs-Nvidia-RTX-2070-Mobile/m704710vsm694798 So, is it more crucial an Octa-core CPU or a 16GB VRAM GPU?

  2. Well, as seems so: And... they say Intel encoders offer higher IQ in the end : ) On the other hand:

    Emulating the texture of film

    For some time I've been thinking about the texture of film. I've also been thinking about the texture of RAW images, both 4K and also 1080p. And I've been thinking of the texture of low-bitrate cheap digital camera images, and how much I don't like it. Last night I watched Knives Out, which was very entertaining, but of note was that it was shot by Steve Yedlin ASC, and that it was shot in 2.8K RAW and mastered in 2K. For those that aren't aware, Steve Yedlin is basically a genius, and his website takes on all the good topics like sensor size, colour science, resolution, and others, and does so with A/B testing, logic and actual math. If someone disagrees with Steve, their work is cut out in convincing me that they know something Steve doesn't! This inspired me to do some tests on processing images with the goal being to create a nice timeless texture. Film has a nice analog but very imperfect feel with grain (both the random noise grain but also grain size of the film itself which controls resolution). Highly-compressed images from cheap cameras have a cheap and nasty texture, often called digititis, and is to be avoided where possible. RAW images don't feel analog, but they don't feel digital in digititis way either. They're somewhere in-between, but in a super clean direction rather than having distortions, with film having film grain which isn't always viewed as a negative distortion, and highly-compressed digital having compression artefacts which are always viewed as a negative distortion. Here's the first test, which is based on taking a few random still images from the net and adding various blur and grain to see what we can do to change the texture of them. The images are 4-7K and offer varying levels of sharpness. The processing was a simple Gaussian Blur in Resolve, at 0.1 / 0.15 / 0.2 settings, and adding film grain to kind of match. On the export file the 0.1 blur does basically nothing, the 0.15 blur is a little heavy handed, and the 0.2 looks like 8mm film, so very stylised! The video starts with each image zoomed in significantly, both so that you can see the original resolution in the file, but also so that you can get a sense of how having extra resolution (by including more of the source file in the frame) changes the aesthetic. Interestingly, most of the images look quite analog when zoomed in a lot, which may be as much to do with the lens resolution and artefacts being exposed as it has to do with the resolution of the file itself. My impression of the zooming test is that the images start looking very retro (at 5X all their flaws are exposed) but transition to a very clean and digital aesthetic. The 0.15 blur seems to take that impression away, and with the film grain added it almost looks like an optical pull-out on film was shot of a printed photograph. In a sense they start looking very analog and at some point the blur I'm applying becomes the limiting factor and so the image doesn't progress beyond a certain level of 'digitalness'. In the sections where I faded between the processed and unprocessed image I found it interesting that the digitalness doesn't kick in until quite late in the fade, which shows the impact of blurring the image and putting it on top of the unprocessed image, which is an alternate approach to blurring the source image directly. I think both are interesting strategies that can be used. Now obviously I still need to do tests on footage I have shot, considering that I have footage across a range of cameras, including XC10 4K, GH5 4K, GH5 1080p, GoPro 1080p, iPhone 4K, and others. That'll be a future test, but I've played in this space before, trying to blur away sharpening/compression artefacts. There are limits to what you can do to 'clean up' a compressed file, but depending on how much you are willing to degrade the IQ, much is possible. For example, here are the graded and ungraded versions of the film I shot for the EOSHD cheap camera challenge 18 months ago. These were shot on the mighty Fujifilm J20 in glorious 640x480, or as I prefer to call it 0.6K.... IIRC someone even commented on the nice highlight rolloff that the video had. All credit goes to the Fuji colour science 😂😂😂 Obviously I pulled out all the stops on that one, but it shows what is possible, and adding blur and grain was a huge part of what improved the image from what is certain to be several orders of magnitude worse than what anyone is working with these days, unless you're making a film using 90s security camera footage or something.

  5. There are reports the fast h.265 handling is faster but lower quality comparing with the Intel capabilities. Will ProRes or other have the same issues? I also had asked it there but no answers so far: I also wonder if h.265 transcoding / encoding with software isn't possible to overcome those issues of M1 hardware?

  9. You have hit upon the crux of the matter, lighting. We would all like a magic sensor (me included) that would lift shadows for 6 stops and lower highlights for 8 stops but really if you are in that situation, you should either light your main point of focus (not the whole scene if you do not have the means to do it) or you are possibly going for artistic, high contrast effect . Don't get me wrong I have had similar thoughts but at the end of the day I think that the FF argument is a bit animal-farmish (FF good, aps bad). Masterpieces have been filmed with way lesser sensors than we have. It is in the nature of the age to rush through things I suppose. Sony has the best sensors for low light ( I have had them in my Fuji's for years now) and I bet that my X-t3 at 3200 iso is cleaner or as clean than the C70 with its ridiculous price tag. Day By day I am getting disillusioned by the frankestein rigs surrounding a DSLR in order to shoot. the c70 is the right idea at a very wrong price 🙂

  10. As a pro Nikon user for 40 years, I have mixed feelings here. I love my d850 for its still image quality and features. But I’d guess their contract with Sony for the sensor limited the video features and codec. As I look to making more video, I only have to look at a used Lumix GH5S for example to see a simple solution for exceptional video features and in-camera 10bit, which for me are more relevant than full frame vs m43. Disappointed by the Z ii offerings. So I won’t invest in a Z body, and will instead likely add a video-centric camera from another maker, even as I still swoon over my 2-year old Nikon 850.

  11. Cinematography has never or will continue to rely on fullframe. Fullframe helps with noise, and depth of field in tight spaces with wider lenses, but S35 still delivers great IQ when used well. I appreciate hybrid users will favour fullframe, its where many of the camera choices are based and popular for Photography, but if you're dedicated to video, S35 is still the preferred format option in camera choice.

    S5 vs A7S III - High ISO

    You are correct. The x-t3 sensor is Sony derived and that has been the case for models

  13. Only just got it and not done enough to test it yet. Everything feels solid and snappy so far. Got Resolve 17.1 beta on there. And LumaFusion iOS app runs natively in MacOS on it. Interesting to try that with a mouse and keyboard. I am sure there will be throttling. No fan. Not even a vent. But it's like complaining the car you use to do the supermarket run is only coming 12th in F1 qualifying rather than pole position. Shouldn't even be talking about high-end video tasks on this class of laptop 🙂

  15. M1 goes back to the ARM1 in 1985 which is a chip I brushed shoulders with as a young kid familiar with the Acorn / BBC Micro computers at the time (and in the early 90's) in British schools. RISC architecture was showing some serious strengths way back then. When you take Moore's law and many years of Apple investment in efficient mobile silicon you get this... An actual 64bit CPU core occupies a tiny part of the die, and the integrated GPU about one quarter. The DRAM is pretty much on the same die and is accessed extremely effectively by both CPU and GPU. I took delivery of the MacBook Air M1 last week, from Amazon for £999... It is an ultra thin / featherweight class affordable consumer laptop. With a motherboard the size of a small TV remote control And probably only a little larger than what's in the iPad Pro. So I booted it up and put something very intensive and demanding on... Top-end PC game designed for Nvidia RTX cards and Intel CPUs. It runs via Steam, via an interpreter (Rosetta 2). Not even a native app. First signs this is not a normal fanless ultra thin laptop is I easily get 60fps with good looking graphics, nothing turned down all the way. The resolution looks so good, as if there's either upscaling, some A.I involved or some new kind of display scaling magic going on. Yet this is with the performance hit of Rosetta (about 20%), on a PC game port running x86 code with integrated graphics!! It smashes... demolishes... everything else in the same class. Intel, Nvidia and AMD should be extremely worried. When / if Apple scale up this architecture to 32 core high-end consumer territory with a fan and dedicated Apple GPU, the rest are in trouble. There is so much custom silicon in the CPU... video editing, encoding, image editing, all buttery smooth so far and this is the least powerful Apple silicon machine they will ever make.

  17. LOL Indeed, there's not a single answer to take : ) Getting a machine for editing/grading/post-production depends a lot on software optimization and distinct parts of the hardware resources required to handle much different tasks :- ) Some of them work just fine and... anyhow awkwardly some under circumstances too, in fact. I am now buying a couple of units of the ASUS Zenfone 7 Pro for 3D UHD capture at 120fps... go figure! ASUS staff can only think I am crazy (I guess they actually do!) and my partner in crime who has already worked as Peter Greenaway stereographer in the past, other than supervising Godard's stuff, as for instance, is puzzled with my decision, so... What can I tell you more sideways? ; ) Those guys on that YT channel up there look like to know their job fairly enough (as well, the fella Max), I find their views honestly interesting on topic BTW: https://www.youtube.com/channel/UCnMf3jl6DDzvPrm5RToktuA

  26. Bottom line is this camera is a game changer for BM. It’s the camera where finally a custom made sensor and BRAW come together. REDs are jewelry cameras in a way. A status symbol work tool. The Hilti power tool guys that can’t believe you used Dewalt to make your deck. Now what they should do is get BRAW in other brands cameras ASAP.

  29. RED had a similar reputation not all that long ago. It takes a big innovative splash to make people change ships...once they do you have a chance to shake up the market. I think this camera will make enough RED users jump ship and then it all comes down to this specific camera and how good/reliable it is. There’s no reason to think this camera isn’t how Blackmagic enters that conversation. None at all.

  30. This is all because of this cofake-1984 pandemic hoax... People be aware. They are destroying jobs, economy, everything, for the great reset. These draconian measures are being implemented by these technocrats globalists... There is no pandemic. No health problem, only a political one... Devide and conquer, this is their aim... We have to fight their agenda... otherwise we will be all out of business soon. There is no cure for the hunger virus. https://www.bitchute.com/video/zH8UjevO3O4m/

  31. Yes, everything that goes against the official narrative, makes you mad, because you cannot live in a world other than the one thought world, you cannot live without believing that the system cares for you: The nazis used to say: it is for your own safety... so you use the same strategy communist use to avoid discussion, that is. labeling people: like tinfoil, saying that someone that question this covid fake pandemic believes in flat earth, is a conspiracy theorists.... well, I f I'm all of that, and if you believe that something created by Bill Gates's propaganda machine, that affects only 1% of the entire population can harm you, well, you are just a useful Idiot, as Lenin said... I know the forum right for you: its called OCD Forum, it deals with the virus fear paranoia, and it has no cure, unlike cofake LOL Here your Savior... LOL

  32. I wish... Covid 19 is destroying business, as it was planned, by the great reset-the 4th revolution. It ruined my life, and many others... It is an important subject... it is an unavoidable subject right now, because it is the cause of all this economic crisis, not the virus of course, it never was about the virus, but the draconian measures taken... I fear for the camera industry... chinese smart phones will kill the business, now with the help of covid measures, and corrupt leaders... 😞 https://www.telegraph.co.uk/global-health/science-and-disease/covid-19-could-kill-people-hunger-virus-warns-oxfam/
