Without detracting from Graeme's work, it should be made clear that none of the algorithmic REDCODE specifics described in the text are non-trivial for "skilled artisans". I don't think any of this will hold in court as a significant innovation. A few notes: Re: "pre-emphasis curve" used to discard excessive whites and preserve blacks. Everyone here knows it very well, because every log curve does this. Panalog, s-log, Log-C, you name it, do that. In fact, non-linear curves are (and were) so widely used as a pre-compression step, that some camera companies manage to shoot themselves in the leg by applying them non-discriminatively even before entropy coding (where a pure log/power curve can be non-optimal). JPEG has been used since the early 90's to compress images. Practically all images compressed with JPEG were gamma encoded. Gamma encoding is a "simple power law curve". Anyone who has ever compressed a linear image knows what happens (not a pretty picture) to linear signal after a DCT or wavelet transfrom, followed by quantization. And there is nothing special, technically speaking, about raw -- it is linear signal in native camera space. But you don't need to look far for encoding alternatives: film has been around since the 19th century, it does a non-linear transform (more precisely, log with toe and shoulder) on the captured light. In an even more relevant connection, Cineform RAW was developed in 2005 and presented at NAB 2006. It uses a "pre-emphasis" non-linear curve (more precisely, a tunable log curve) to discard excessive whites and preserve blacks. You may also want to consult this blog post from David@Cineform from 2007 about REDCODE and Cineform: http://cineform.blogspot.com/2007/09/10-bit-log-vs-12-bit-linear.html Re: "green average subtraction": Using nearby pixels for prediction/entropy reduction goes at least as far back as JPEG, which specifies 7 such predictors. In a Bayer mosaic, red and blue pixels will always neighbor a green pixel, hence using the brightness correlating green channel for prediction of red and blue channels is a tiny step. Re: using a Bayer sensor, as a an "unconventional avenue": The Dalsa Origin, presented at NAB 2003, and available for renting since 2006, was producing Bayer raw (uncompressed). The Arri Arriflex D-20, introduced in November 2005, was doing Bayer raw (uncompressed). Can't recall the SI-2K release year, but it was doing Bayer compressed raw (Cineform RAW, externally) in 2006.3 points

Fusion is the after effects replacement, it just is a completely different interface. I'm trying to wrap my head around it as well. Keeping up with software is a job in and of itself. With Blender's recent overhaul I'm committed to learning it to the point of doing 3D animatics for storyboarding and basic visual effects like tracked fire and explosions. We'll see how successful I am with that endeavor!2 points

I found this on a site about h.264 license. Q: Is it safe to use such patented algorithms? A: Patent laws vary wildly between jurisdictions, and in many countries patents on algorithms are not recognized. Plus the use of patents to prevent the usage of a format or codec on a specific operating system or together with specific other software might violate antitrust laws. So whether you are safe or not depends on where you live and how judges interpret the law in your jurisdiction.2 points

Anyone interested? This Lut fixes the brown tint, gamut clipping, roll-off issues, skin etc. and is made to look similar to RED IPP2 Soft Rec709 conversion - a conversion Lut to RedWideGamut/RedLog3G10 for a native IPP2 workflow is also provided. Can't wait to hold the Pocket 6K in my own hands - seems like it's more color accurate.2 points -

RED respond to Apple in compressed RAW patent battle
Display Name reacted to Andrew Reid for a topic
All that can indeed happen, plenty of room in the market for everyone. But it would be foolish of RED to not enforce their legal rights where there's millions of dollars involved in potential licensing fees so I can see why they are engaging Apple in the patent dispute. In the smartphone industry as well this happens all the time, and they can all sell their similar technology but somebody needs to sort out the economic side, and that's what the US patent office is for I guess. Personally, as a filmmaker I just want everything for free Come on Nikon hurry up with that internal ProRes RAW for $1.5k1 point -

RED can still sell cameras with REDCODE. ARRI can still sell cameras with ProRes, ProRes RAW or cDNG. Any manufacturer can release a camera with compressed RAW. Sigma can release the fp with cDNG and ProRes RAW internal. Blackmagic could expand BRAW. Apple is seeking to invalidate the patent. They aren't taking control of it. Then the market will settle the rest.1 point -

Kisaha, I do this all the time. It really isn't that big of a deal. Virtually all of my events are at least 3 cam events. I set the time codes on each camera and syncing later is a breeze. You will invest in more storage and soon not think much about it. I have in excess of 100TB of storage, plus online storage (S3, etc.) As for which cam for a live event like that, I believe that I would personally bring the P4K - mostly without a speed booster. There are some really good zooms for M4/3, like the Panasonic 35-100 f/2.8 or the Olympus 40-150 f/2.8. That would give you good low light performance in a portable package. Although, in an event like that, I would really lean toward something like an A7iii for the really good low light performance and much superior focusing ability. But, yes. The editing will take longer with the 6K footage and the storage requirements are at least double. On my machines, I have noticed little difference in playback in Resolve between the P4K and the P6K footage. All of our machines are at least 4Ghz, quad-core processors, with SSDs, so they aren't beasts, but are decent spec'd machines.1 point

if i could have found a gopro 3 or 4 black i would have bought it for the $200 challenge as well. Something to be aware of is the colour shift that happens with the gopros when you change lenses with the 3's and four's doesn't happen with the 5 well i thought it didn't happen with the 5 but this site says it does. basically you will get pink edges the only way to fix it is to a $50 (or used to be $50 download, its now $25, business must have slowed alot) to change the lens profile somehow. https://www.peauproductions.com/products/service-remove-gopro-lens-profile-no-pink-corners1 point

i liked webrunner, i will miss him... and no doubt he had a lot of experience that he tried to or could have imparted to the forum. Having said that he was about as tactful as a sledgehammer and it was his way or the highway. Personally i don't think that cuts it in this day and age. Sometimes a line has to be drawn in the sand a point to which someone will go to but no further. A camera forum is not a battlefield, and its not life or death either. if you cant distinguish between the two your probably missing the whole point of having a camera in the first place. mercer is american i believe I dont have hate for him ? in fact of the entire forum, he seems to be living the dream.

RED respond to Apple in compressed RAW patent battle
sanveer reacted to Cliff Totten for a topic
Atomos becomes happy friends with Apple. Apple gets ProResRAW to promote Final Cut. Atomos provides the recorder that gets arround the "internal" raw recording pattent. Everybody is happy. Camera's just need to give non-compressed raw output. No legal worries for any camera company as Atomos handles the rest. Everybody is still happy. Apple suddenly turns arround and attacks RED's "internal" pattent to potentially kill Atomos' only reason for raw over HDMI's existence. If Apple wins, ProResRAW or equivalent can be recorded INTERNALLY by any camera....effectively leaving poor Atomos' raw over HDMI dreams out in the cold. It literly wont be needed anymore if Apple wins. Atomos to Apple - "Thanks for nothing good buddy" Wow!1 point -

So I keep meaning to do something more elaborate for the BMMCC but never have the time but I had an hour free this afternoon to knock this together for anyone who wants something cheap and easy to base a DIY controller on. Basically, its a 6 channel servo tester that costs £15 from Amazon ( https://www.amazon.co.uk/LewanSoul-Channel-Digital-Over-Current-Protection/dp/B073XZH264/r ) and a £5 solder less VGA breakout from Amazon ( https://www.amazon.co.uk/sourcing-map-Breakout-Connector-Solderless/dp/B07MQX1BBP ) (Yes, I've soldered the ground but thats only because mine must have been made on a Friday afternoon and they put in one side of the connector wrong ) With this, you can use the rotary pots to control four parameters on the camera so you could use it to have physical control of focus, aperture, ISO and WB etc. I've shown the solder less breakout as it makes things really easy for anyone to connect up (it has a shell to enclose it obviously) but you can just solder to a connector if you want to. Obviously you will want to use longer cables than these test ones ! The connections from the breakout to the servo board are BMCC PIN 1 > SERVO BOARD - BMCC PIN 14 > SERVO BOARD + BMCC PIN 3 > SERVO BOARD SERVO 0 S BMCC PIN 8 > SERVO BOARD SERVO 1 S BMCC PIN 12 > SERVO BOARD SERVO 2 S BMCC PIN 13> SERVO BOARD SERVO 3 S You then assign the functions that will be controlled by the pots on the servo board in the remote menu of the camera by setting the functions to be controlled by PWM1-4 respectively. (servo pot 0 is PWM1, pot 1 is PWM2 etc). So if you want to build your own DIY physical controller thats all you need to know to get it going and then its up to you how you case it etc. Because the BMMCC only has 4 ports you can control through then you have got two spare controllers which if you wanted to get fancy you could connect actual servos to for controlling manual focus lenses, zoom control etc.1 point

I just told Adobe to shove it
gethin reacted to fuzzynormal for a topic
So much this. WTH/F Adobe? There's no reason with their budget that they couldn't have released a cohesive "PRO" version of their editing software with strict hardware requirements and support so it's an effective reliable tool. Nope, just an endlessly buggy BS. My favorite new annoyance is this: I do a lot of slow-mo, and I like to shoot in 60p. So, I batch apply 50% speed to my clips for my 30p sequences. In bins I can scroll the thumbnails, which is helpful. However, latest version, for no discernible reason, will now "blank" all thumbnails of clips with any speed variance applied. They get turned to black. So now I'm looking at a bin full of black thumbnails. Basically, making thumbnails of clips with speed adjustment useless. https://forums.adobe.com/thread/2622768 Yes, it's not the end of the world, but it affects the workflow. One needs to fight Premiere to work effectively. That's always been the problem. It just doesn't play nice. I've been using Premiere on and off since version 1, so I know it's always been a problem child. Had a 15 year run there when I was on Final Cut and that was nice. One of my colleagues is still using FCP. I might return to it although I don't find it as appealing as the traditional version. Ugh, I dunno. Gave Resolve a spin but their version of using proxies was unreliable and everything I do is proxy editing...so still looking.1 point -
Based on comparing the actual sensor size of the Pocket 6K with the JVC LS300 then from my experience the typical VSM setting on most MFT lenses would just cover it. Though even a small windowed crop mode of 5-10% with that extra resolution would be a worthwhile trade off to be able to use those lenses. You think and have seen ? Which one is it ? Your argument or one that you have seen? Either way, can you talk me through how there can be a better argument for the EF mount camera when both cameras could take EF lenses and the MFT camera can additionally use native MFT, Leica M and PL mount lenses ? Based on the arguments you have thought of/seen would your Nikon Z6 have been better to be F mount or is it better to have the shallower Z mount that opens up a whole mass of different lens options and also be able to use F mount as well then? MFT P4K users ? As opposed to what? Users of the non-existent EF P4k? You are conflating two entirely different things. These are different cameras and hence why the reaction from people who actually own the Pocket 4K has been largely muted because either they aren't that bothered about the extra resolution or prefer the extra flexibility of the MFT mount or don't want to spend the extra money to trade up the camera and the increased IT costs of dealing with 6K or some combination of all of those. And some owners have gone "great, I'll buy the 6K one and use that as well". As much as you'd clearly likely there to be a massive outpouring of rage from Pocket 4K owners about this new camera, it just isn't there because this is not a Mark II version of the Pocket 4K thats come in at the same price with more resolution, it is clearly a different camera. For anyone with a bizarre fetish for revelling in and stoking other people's outrage, I can see that that would be a disappointment but it doesn't alter the facts. Now, if the Pocket 6K had come out with an MFT mount at or around the same price then you might well have needed a few extra boxes of Kleenex and some screen wipes but thats because that would have been a Mark II version of the Pocket 4K. But then of course, that would also be related to it using the same, more flexible, mount. You can't get any detail on the P6K if you can't get your lens on it. Are we just going to gloss over the fact that you can't mount the vast majority of PL lenses on it or does that not now matter for a cinema camera ? There are flaws in a lot of the side by side tests but if we let that slide then considering its twice the price then it should really shouldn't it? Which is why its whats known as a different camera.1 point

You only have to use Resolve for color grading, then edit down and transcode the footage out to ProRes HQ. Then FCPX or PP. It's not the issue most make it out to be. Resolve has killer color grading set up that blow FCPX and PP away. But for editing Resolve is not fast enough for me. And I love FCPX.1 point
