  1. Thanks all. I was really hoping for a link to an $30 ebay USB dongle. I was kind of thinking of a laptop as kind of a half-way measure between having an on-camera monitor and having a huge TV/monitor on set like is common on big productions. I wouldn't carry around a laptop for my run-n-gun shooting, but if you're shooting in a single location then I don't see why a larger screen wouldn't be useful. I've had heaps of things that I shot on the GH5 and they looked fine on the monitor (or the viewfinder which is higher resolution) but were completely fubar when I saw them on my 32" display, and I'm not sure that a 7" display is really large enough to be a perfect proxy for a 32" 4K display, let alone a 65" 4K TV or a projector setup. And before anyone tells me that big productions use 7" monitors just fine let me say that I watch Netflix / Prime on my 32" 4K display and I see out-of-focus shots all the time.... There should be a chip that is HMDI to USB and there should be a factory in China just pumping out the standard implementation circuit from the spec sheet at a very small markup to the parts cost. Surely?

    I think of it much less like marketing and more like market research. There’s a principle in market research that you can ask someone if they would purchase something and get an answer, but it’s only if you ask the person to actually buy that you get their real answer. Lots of people will tell you your idea is good, or that they would buy, to make you feel better, or they don’t like saying no to people, or they’re optimistic, or excited by the idea, etc but it’s not reality. Why design a product, fit out a factory with tooling, manufacture a bunch of products, market the shit out of it, and only then discover that the people in the focus group who said they were excited to buy it were just being nice... ? These crowdfunding campaigns are more valuable to manufacturers in market research than they are in anything else.

    Extreme telephoto work

    @leslie lots of ways.. You can either do the whole image, I’d suggest playing with the Gamma or Gain wheels and see if you can get the sun and the smoke the right colours at the same time. The other approach is to do a key of just the sun, and then you could try the same things, or try the Hue vs Hue and shift it towards red/orange and further away from pink/magenta.
  4. @heart0less - that is a fascinating video. Thanks! What I found interesting about it is: They credit the guys at LiftGammaGain (I suspect most similar videos come from people who either don't know about LGG or plainly rip it off without saying) They mention a LUT for all of 2 seconds before talking about everything except colour They made a complete tutorial that didn't include possibly the most significant things that (IMHO) make something look like film They also did something that I think was great - they showed the LGG thread. A quick search and now I can go read it! The thread is only about halation and gate weave (which I had to look up - it's the jumping around that film does - like why the credits move around when being projected). It's also interesting that it's started by Jason Bowdach whose name was familiar - he'd written one of the reference articles on film emulation that I refer back to on occasion.. So, all that said, here are the other links that I've found that are useful if you want to emulate film... To start, this article is very good and talks about non-linearities and saturation behaviour: https://www.provideocoalition.com/film-look-two/ It also links to this very interesting video showing how Alexa handles things: Noam Kroll has a decent write-up: https://noamkroll.com/how-to-make-your-digital-footage-look-like-film-in-post-production/ The article from Jason Bowdach that covers a lot of ground: https://blog.frame.io/2019/10/21/emulating-film-look/ and lastly the article the video above references: https://liftgammagain.com/forum/index.php?threads/halation-and-gate-weave.13056/ of course, after all this, the film look really comes from lighting and composition in the first place, and remember that if you want the film look then it's better to first get someone to look at your film (ha ha) so it should be entertaining in the first instance Film is probably an infinitely deep rabbit hole....

    Extreme telephoto work

    Yeah, the focus would be hard - for football season I shoot highlights at my kids games and so I spend a bit of time manually pulling focus at around 200-400mm equivalent, but you're in another whole league at 1500mm. One challenge I have with my rig is that it's on a TC and also a dumb adapter but the lens doesn't have a hot shoe, so it's being supported by the camera (and I also hold the weight of the lens with the hand that's focusing) but getting some additional lens support would be ideal in future. That is a really cool video and awesome zooms. Thanks for posting the article, some good tech talk in there and it makes sense they would have needed a robot - those focal lengths are really difficult to manage, especially with those fast transitions. Luckily the sun doesn't require me to move the camera!! lol, let's hope! One of our neighbours has a two storey house with a balcony and they're often out there so I'm not the only one. Of course, I can't really see into other peoples backyards from that angle either, so there's that. well, not an optical viewfinder anyway! I have no idea at what point the sun is too much, but I'm shooting without filters, although at F4 the lens is hardly super fast. Thanks - interesting setup. I went with the oats solution as it keeps the camera low to the ground so that air is only going to go over the top of it rather than around it with lots of turbulence, and the oats also provides multiple points of contact rather than there being a single point subject to flex and twists. My tripod would have to be at eye-level (and I'm over 6 foot) to see the horizon, so at it's least stable configuration basically.
  6. Interesting film from Blackmagic... Shot on P6K, post in Resolve 16, and the credits say "Produced in 14 days" so presumably a short timeframe project. What I think is interesting is that (although it doesn't say it) I suspect that the whole production was done in Resolve, so that likely means that all the VFX are from the Fusion page. This would be pretty cool as I think that the Fusion page has huge untapped potential and we haven't seen it in use yet as the people who really know Fusion are off getting paid not being on YT. It would be interesting to see some BTS, especially of what happened in post for this.
  7. The other day I noticed the sunset and decided to have a go at filming the sunset at super-telephoto so that the sun fills a large section of the frame and you see all the atmospheric distortions and stuff. First attempt was a write-off because I stuffed up the focus. Second attempt was better as I was able to focus better, and then closed the aperture a few stops to make sure I got it. I stuffed up the settings as I still had it on my normal auto-exposure and auto-WB, so that's why I'm only posting this still, however I think I'm getting closer.. This was shot in 4K but I think next time I will do a normal time-lapse and get the benefits of RAW and a better ISO as there is quite a bit of grain in the file. The setup seems to work though: GH5, Canon FD 70-210 F4 at 210mm F11, Canon FD 2x TC. Setup on a packet of oats for stability in the breeze we had, and on top of a pillar on the fence. I suspect that at 840mm equivalent that stability is one of the key factors here, and the oats seemed to do the trick. Once I get it all setup then I can probably put a bag of pasta or something on the top to further damp it and deflect some of the wind. Yesterday was cloudy so no sunset, but hopefully tomorrow I'll get another go with fixed settings and in time-lapse mode and I'll be able to post a video instead of just a still Anyone else shooting longer than 600mm, or 800mm equivalents?
  8. Can I use a laptop as a large portable HDMI monitor, presumably via some kind of USB HDMI in type adapter/dongle and some software that allows viewing (and maybe some cool features like LUTs, false colour, focus peaking etc). It seems ridiculous to suggest that I have to buy a HDMI monitor when that means I have to re-buy the screen, buttons, battery etc that are already in a laptop. Surely there's an adapter that's cheaper than a monitor with focus peaking and various features? I'd be looking to use it with my GH5 for critical focus when I'm either too far from the camera to see the floppy screen, or when I can't check focus well enough using the (rather mediocre) focus peaking that it delivers.
  9. Totally agree. Although, considering that your comment about film stock is very relevant here and that's now the sensor and CS which means it's the camera too, I'd say it's Lighting, Lenses, and Camera (in that order!). Of course, the full list is more like: Story, Acting, Sound, Lighting, Cinematography, Lenses, and then Camera (in that order!)

    Sirui anamorphic

    Naturally, I choose the cheapest single-focus lens that matches with my 16:9 camera... oh wait!
  11. Thanks to @noone for posting that link to lensrentals - that article completely changed the way I think about DoF and lenses. I hadn't previously made the link that field curvature is actually a map of DoF, so that's hugely useful. It also has a number of very significant consequences, and may help to join together DoF, field curvature, the FF look, how an image transitions between in-focus areas and out-of-focus areas, and 3D pop. I'm contemplating and will return with my thoughts once I've re-adjusted my head and worked out what this means.

    Sirui anamorphic

    @Julien416 I agree. Let's agree to disagree ??? It's probably a fine point, but your original post said "all the people" and "everyone". I was just trying to bring some balance into the equation. You might be right that the vast majority of people shooting anamorphic want a less clinical look, but from my cine lens thread I also quoted some people talking about the Master Anamorphics: It might just be a pet annoyance of mine, but so often people talk in absolutes now, and I think it just divides people, creates friction, encourages polarised thinking, and discourages critical thinking. I find politics to be very prevalent with this issue - if "everyone" (or even "all" the smart people) share your opinion then there's no reason to talk about issues, exchange views, and heaven forbid(!) actually learn something new. Anyway, rant over. PS, if you want to shoot anamorphic on a budget then maybe buy the lens and dirty it up in post! Or buy a vintage spherical and crop it. Or whatever. This lens doesn't somehow make all the other lenses disappear. in fact, it makes them cheaper

    Sirui anamorphic

    I disagree. It might be that the defects are a common reason that people shoot anamorphic, but it's not everyone. Here's a video that includes the Zeiss / ARRI Master Anamorphic and it renders an image almost as technically perfect wide open at T1.9 as other cine lenses at T4. I suspect that shooting anamorphic because you want the flaws is a low budget thing (and because at low budget you can't get sharp well-behaved optics so there's no choice). It's like saying that people only shoot FF to have shallow DoF. Or MFT because they want a small camera. You might make the point that Hollywood cinematographers often like vintage glass because of the softness and rendering, which is true, but there's also a large segment of Hollywood that have the attitude of capturing things in the highest quality possible (meaning highest resolution and most neutral rendering) so that they can push the image around in post later on. It's not a POV you hear a lot, but lots of big movies are shot with this principle.
  15. @heart0less that's very interesting because out of all the mega-dollar cine lens tests I've seen so far I don't recall there being a single Panavision lens amongst them. Of course, maybe one or two escaped my attention, but not enough to make me remember them. In the above: Panavision = 29 ARRI = 12 Cooke = 7 Angenieux = 4 the rest only got 1... Maybe we should buy Panavision lenses and it will make us automatically famous.... on second thoughts, I can't find a singe cine Panavision lens for sale. I guess it's beyond those things where the price says "if you have to ask it's too much" and all the way to "if you don't know where to ask then it's too much"!!!
  16. Well, that's definitely a credit to Sony as I haven't spotted a single clip with colour issues. My understanding of Sony colours is that they are the most accurate but that people don't find them pleasing, and that their log profiles can be hard to grade. But having said that I haven't worked with Sony footage (apart from my new X3000 action cam) so none of that is from personal experience. Sounds like the OP should just use the default settings......
  17. Interesting. That's different to the A7Sii where IIRC he had customised one of the profiles. Do you know if he's doing a lot of colouring in post? I'm not familiar with the look SOOC.
  18. Not sure if it's the easiest, but I can recommend Davinci Resolve as an all-in-one NLE. There's a free version that you'll be able to use for basically everything you will need. It's one of the premier colour grading packages used in Hollywood, so the restrictions on the free version aren't aimed at the enthusiasts. FCPX has lots of devotees and PP also does although apparently it isn't that stable and people are starting to leave it to get better reliability.
  19. +1 for getting white balance right in camera. Sony is known to be harder to get good colour from but that just means that you have to be more particular with WB and processing in post. Kraig Adams on YouTube is known for getting great results in camera and is currently using the A7iii. He made a few videos about it that might include his colour profile and settings.
  20. Did those specs say that readouts were at 12-bit (and higher)? Or is that all sensors and the manufacturer just chooses 8-bit regardless?

    Lenses

    @leslie did you put an anamorphic lens on your gopro? Or just replicating the aspect ratio? In terms of getting stability I'd suggest doing it right and only having to do it once. If you can look at how rails systems work and learn how they've solved the various design issues while keeping flexibility then fabricate something that applies those principles then I think that would probably be worth the effort.

    Sirui anamorphic

    It's interesting that the 50mm 1.8 is perhaps the most common lens design, and if we take an image circle designed to cover a FF sensor and applied a 1.33x horizontal crunch then that would line up pretty well with an APS-C crop, therefore making a lens that shares (at least some of) its optics with the cheapest and most common lens design ever made. I suspect that's pretty much the recipe for how they made this lens - get a 50mm 1.8 design and apply some optics that give the 1.33x and there you go. This makes Sirui the anamorphic equivalent of Yongnuo, which seems like a great thing for anamorphic shooters everywhere
  23. @mojo43 watched the video - cool stuff! It's definitely a striking result, and you explained it pretty well. Some thoughts if I may.. Yes, please make more videos showing your grades One thing I've noticed from other grading videos is that they start off by talking about the colour, but every time they touch a control they then explain what the control is and how to use it (literally things like which way to drag the mouse to change the value) and I find that really infuriating, so don't fall into the trap of over-explaining the tools (which you didn't) How to use Resolve is covered by many many people, but what isn't covered is the art side of it, both from a perspective of talking about what you're seeing (eg, how to choose a good amount of contrast and what you're looking for) as well as from a perspective of why you want that much contrast and how that relates to the content of your film (eg, how colours link with the emotions of the characters, etc) If you can talk about the art and not how to use each tool then you'll find yourself without that much competition, and the videos will be useful to people who already know how to drive the tools. I'm looking forward to the next one!
  24. I'll watch when I get home, but you're right about not so much on YT. I started a thread about Resolve and colour grading just to collect resources so that we can share them - it's here:
  25. Just found this guy - looks like he knows what he's talking about....
