  1. Sadly, these forums are one of the most enlightened places online. The current state of film-making is at an all-time low due to availability of equipment and popularity of outputs. Is this a good thing or a bad thing, well, that's up to everyone to decide for themselves, but the average discussion online will very confidently tell you that: FF is better there are people who say sensor size doesn't matter, but they're basically triggered all the time and sound crazy you choose the colour science you want by buying the best camera (and half the people can't even spell LUT, let alone understand that you can colour grade to match cameras) the only measure of a camera is the resolution of the sensor the only measure of a lens is the size of the aperture the only measure of a lens is how sharp it is at its widest aperture the best lens if you're not on FF is the Sigma 18-35 BM are the best cameras available BM owners don't know anything about anything and should be banned from owning cameras etc If you think Hollywood is immune to these trends, then think again. It took a while for them to get FF fever, but they got it in the end, and when they talk about sensor size and lenses and shallow DoF it's just word-salad coming out of their mouths and they know about as little as the average social media bro with a FF Sony...

    Pocket56K

    Link above is broken - here's the real one: https://spectrum.ieee.org/the-world-s-largest-camera-is-nearly-complete
  3. I often watch YT in various resolutions, from 4K to 480p, and I've noticed that the 1080p quality can be hugely variable. Some content looks great and other stuff looks absolutely atrocious. The only thing that seems to predict it is the quality of the camera, however we all know that better cameras are typically used by people who pay more attention to things like uploading at an increased bitrate etc, so it may not be the camera but something else from the image pipeline. If they went 1080p-limited it would be great to see a bump in the associated bitrate, although I suspect that wouldn't happen. For some reason everyone seems to allocate constant bitrate per pixel, completely ignoring the fact that screen size is a completely independent variable.
  4. That would be brilliant!! The vast majority of people wouldn't pay to watch 4K content, YT would take their 4K-preference out of the algorithm, without 4K watching ability most people would stop insisting on 4K content, creators wouldn't be ruthlessly pummelled for not shooting 4K, and the entire platform could switch focus from irrelevant pedantry to actual real content.
  5. For me, if we're talking 'cinema' here, the biggest difference is in lenses and their coverage. If you're buying lenses then the S35 lenses from Sony are smaller/cheaper/lighter, and if you're renting then the zillions of S35 cine lenses out there must be cheaper to rent than those with FF coverage. I understand that the comments from others here also discuss the crop modes of FF cameras, which is also a logical comparison. Words in the English language are constantly evolving, being co-opted for good and bad, etc, but I'm wondering if a new definition is evolving? If you take an enormous step back, then you see that there's roughly the following categories for cameras: Smartphones Point-and-shoot (integrated lenses) Consumer video cameras (hand-held, integrated lens) Professional video cameras (ENG style) Hybrid mirrorless (often photo-first designs, typically quite ergonomic, no support for rigs) Cinema cameras (video-first or video-only, integrated fans, mounting points, etc) Looking at things from this perspective, which is really the perspective of the 'content creator' who shoots with a variety of tools, the FX30 is more akin to a cinema camera. If you're someone that exists solely in the world of the professional sets, the fact that Sony call something a "cinema" camera won't fool you at all and is a pretty inconsequential label to add to it. You could make the argument that cameras like the R5 and GH6 and FX30 might be best put into an additional category rather than the ones I listed above, but if you had to choose then lots of cameras without these 'essential' features fit much better in the last category than any other.
  6. The internet can be magic, but not that kind of magic!
  7. The problem with digital sharpness is that it cannot be un-done. If you take a RAW frame, it will have the resolution of the camera/lens with a neutral amount of sharpness. If you then sharpen that image, compress it, and then blur that image, you don't get the original image, you get something that is simultaneously too blurred and also too sharp - the worst of both worlds. If you blur the image sufficiently to counteract the sharpening (and the associated compression artefacts) then you end up with an image that is waaaaay lower in resolution. If, however, the image isn't overly sharpened in-camera (a tiny amount is ok), then you can process it in post without those issues.
  8. Yes, this appears better, but still shows small signs: However, it's nothing to get too excited about. This is a stress-test image, of course, so it would do much better than this in almost all real-life examples.
  9. Here's a test I did some time ago, downscaling an 8K clip to various resolutions then putting them on the same 4K timeline and uploading in 4K. The shot at the end puts them all side-by-side for direct comparison. There are differences, but even pixel peeing, they're pretty minimal. If you're watching something rather than talking tech or doing tests, then it doesn't matter, plus if you add a bit of sharpening to a lower resolution file then it can easily make up small differences. You're right that YT in 4K looks much higher quality than YT in 1080p, but it's a bitrate thing rather than resolution.
  10. Just watched this video from Crimson Engine about camera trends, and he dropped an absolute bombshell.... "We shot and mastered The Devis Fortune [his recent feature film] in 4K, and then when it came time to deliver it to Amazon and iTunes, I was told they would only accept a 2K file, they would then up-res it for 4K delivery if that's what people wanted to watch". Link to the video at that point: I understand that this is a lower-budget film and not a blockbuster and I don't believe it was through a major distributor or studio, so maybe those films are actually uploaded in 4K, but..... How much actual 4K are people watching? Does anyone have more information on this? Wouldn't it be hilarious if all the people watching YT for free were demanding 4K at the minimum, when all/most/some paid content was all 2K.
  11. You're probably already doing this, but in case not, my preferred order of operations is to take two images and try and make a general match first: Make both images black and white and then match levels of white points, black points, grey levels, and then contrast (in that order) Go back to colour and match WB of white points, black points, and then grey levels (in that order) Then using hue curves, match the hue v hue, hue v sat, and hue v lum curves (in any order - sometimes it takes a few passes) Then I apply that correction to a second pair of images and fine tune anything that doesn't look like it matches. Then I apply it to all the shots, and then just look at the whole lot together (or if you can't do that then just watch it on a fast speed) and stop to correct any shots that stand out.
  12. A screen grab works as well, in a slightly different way. Here's some fringing, but it does seem to be well controlled: All lenses will exhibit some degree of CA - it's just a limitation on the various physics involved and especially on such wide angle lenses as these. It's not a criticism or attack. Also, people add CA in post when emulating film, so it's not always even a negative thing. The above grab shows slight over-sharpening, as does the below: It also depends on what you think the ideal amount of sharpening is, which is subjective. Personally, I prefer a high-resolution but low-sharpness image presentation, but everyone is different, depending on the needs of their project.
  13. Looks like you missed both points I was making.
  14. The existing lens may well be soft compared to a high-spec alternative, but I'd suggest that the images from the GoPro are bordering on over-sharpened already, so if the lens is swapped for a sharper one then that is likely to be a net-negative on the overall image quality. It might, however, reduce chromatic aberrations and fringing etc which would be an improvement. I'd be curious to see a comparison between the stock and third-party lenses. I'd also be curious to see a 1:1 crop on the 5.3k files you're recording - could you post a short clip to YT? Instead of downsampling the 5.3K file onto a 4K timeline could you simply put the 5.3K file onto the timeline at a 1:1 scale (which would crop part of the original image). If you're able then including a 2:1 where it's zoomed in to 200% would also be nice.
  15. Ha ha... I guess it's guaranteed to work if I'm filming in my fridge then lol.
  16. What was the ambient temperature during the test? Please tell me it was above 35C 🙂
  17. Yeah, I didn't realise that there was already a thread on it. Let's use the other one. Handy hint - if you use the + button to multi-quote and then browse to another thread you can quote posts from the original thread in the other one, should that make sense.

    Sony FX30 (S35 FX3)

    To me, all cameras give with one hand and take with the other. Those that have some great features pay with other features, and if they have a lot of great features then you pay with your wallet and probably with the size of it. In many ways the best camera is the one that is 7.5/10 in every category because then it doesn't have some 'fatal flaw'. In that sense, the RS is fine - middle of the pack perhaps. How I read something like that is that it's not going to be a problem, unlike if it was notably bad.

    Sony FX30 (S35 FX3)

    Gerald Undone tested the RS and found it to be reasonable (unlike previous Sony APSC offerings). Seems like a good overall camera without any significant downsides, other than it potentially being a new system to buy into.
  20. Sony have released the FX30. Key specifications Oversampled UHD 4K (6K capture) up to 60p UHD 4K/120p capture with additional 1.62x crop In-body image stabilization 10-bit 4:2:2 or 4:2:0 capture in a choice H.265 or H.264-based AVC formats S-Cinetone color profile S-Log2 / S-Log3 with uploadable LUTs for previewing or applying to footage '16-bit' Raw video output No mechanical shutter mechanism Front and rear tally lamps Anyone interested in it?
  21. Extremely sorry to hear this news. Take care of yourself.

    What camera is this?

    Thanks Davide. I suspect it could be either, he used to use a GH5 but I haven't gotten a look at his setup for some time and was curious. He still does a lot of stuff hand-held when he goes into restaurant kitchens and films food preparation etc so the stabilisation and AF are a big deal. It makes sense he'd be rocking a Sony with 16-35 for those, with the AF modes and also the IBIS, plus if it's the 16-35 F4 he'd have OIS on top of that.

    Panasonic GH6

    Yeah, I don't think that the Japanese nor the French have a monopoly on stupidity and other human failings! All countries / cultures have their pros and cons. It's just personal preference that makes each of us prefer one over the other 🙂
  24. Interesting stuff. Pulling out a few select faces to look at detail and skintones etc.... bearing in mind these are all very small in the frame so these are blown up quite significantly. From 2:04 From 3:55 These are all excellent results! Considering that the Prores tests of the iPhone 14 show that their implementation allows the Prores codec to do the best job yet of preserving the complete desecration that the iPhone performs on its image!
  25. It's from one of the YouTubers I watch and this is the best look I've gotten at his setup in a long time. Source:
