RED’s nemesis YouTuber is at it once more – In his newest video, Jinni.Tech claims that the patented methodology utilized in RED’s compressed uncooked format REDCODE is just about an identical to the (JPEG 2000-based) CineForm RAW format with a barely altered GAS (inexperienced common subtraction). He additional claims that RED merely took benefit of the CineForm not being patented and hints on the methodology subsequently being “prior artwork”.Some background to the saga Jinni.Tech vs. REDBack within the pre-Covid period – in July 2019 – we wrote a couple of sequence of movies from Jinni.Tech (an organization behind JinniMags – unofficial media for older RED cameras) that targeted on RED Digital Cinema and significantly RED media at the moment (The RED Mags) and their pricing. These movies prompted fairly the dialogue – right here is our first and second article about these movies from 2019. What adopted – lawsuits and counter-lawsuitAfter this, Bruce Royce from Jinni.Tech uploaded the following episode about RED (half 5 – Crimson phrases of enterprise legality) in August 2020, however apparently he needed to ultimately take the video down for authorized causes in 2022. Not less than that’s what Jinni.Tech claims within the video that’s now reuploaded on his channel.What adopted was additionally a lawsuit by RED vs. Jinni.Tech for “patent and trademark infringement, false promoting, unfair competitors, unjust enrichment, and breach of contract”, however RED “voluntarily dismissed its lawsuit with out prejudice” after studying that Jinni Tech “would probably be unable to pay any significant damages award ought to RED prevail”. Then, there was a counter-lawsuit of Jinni.Tech vs. RED, which additionally was thrown out of court docket.In order you may see, there’s a historical past of animosity between the 2 events. Due to this fact, any data from Jinni.Tech needs to be taken with a grain of salt, as a result of he clearly has an agenda. Nonetheless, he posted a brand new video a couple of week in the past, which raises a more recent accusation towards RED. (I feel he picked a nasty time to publish this video although with most individuals out of workplace in the course of the vacation break …)Half 6 – REDCODE equals QuickTime?Within the newest video, half 6, Jinni-Tech’s Bruce Royce focuses on dissecting the REDCODE RAW compression format. I might advocate you watch the whole video, as he goes on in nice element on why he thinks there are outstanding similarities between REDCODE, QuickTime and CineForm. Within the video description, there are a couple of notes, corrections, and clarifications from Jinni.Tech:9-7 seen within the JPEG2000 isn’t a bit divisor between excessive and low go. That’s the variety of coefficients within the FIR filter and is irrelevant to the bits used. Nonetheless, 9-7 requires twice as a lot operation as 2-6 within the CineForm adaptation. That’s as a result of CineForm codec goals to scale back the compute.Crimson’s inexperienced averaging is extra CPU intensive than CineForm’s. Nonetheless, apparently, the softness within the Crimson’s footage is because of 2 elements: the blur utilized to the output; and their poor demosaicing algorithm.The “pre-emphasis” curve in Crimson’s patent is the inferior gamma curve and never a greater log curve, thus the Crimson one’s poor efficiency within the shadows.Evidently within the early editions of the Crimson one digicam, Crimson didn’t do something to the Crimson color.R3D, JPEG 2000 and QuickTimeAt the start of the video, he seems at an outdated R3D file from the outdated RED One digicam and compares it to an older wavelet JPEG 2000 codec and Apple’s Quicktime video format. He goes on to say and present {that a} R3D file is a typical JPEG 2000 QuickTime video, which can’t be performed in a typical participant as a result of it’s packed inside a non-standard RED-specific wrapper format.Within the subsequent chapter, the video explains how the RGGB sample of Bayer sample of most picture sensors works, what’s demosaicing, and GAS (inexperienced common subtraction). GAS and JPEG 2000This is adopted by additional examination of RED’s patent from 2007 and additional paperwork. In keeping with Jinni.Tech, upon the examination of the Apple vs RED.COM court docket case (and principally the “private declaration in help of the patent” of Thomas Graeme Nattress – RED’s lead digicam techniques architect), the GAS course of is the important thing a part of RED’s patent.Inexperienced common subtraction (GAS) course of. Supply: Jinni.TechThe subsequent half goes again to 1996 and the primary introduction of Wavelet video codec for digital picture sensors by Analog Gadgets. This result in the delivery of JPEG 2000 picture compression expertise finalized in 2001.CineForm and CineForm RAWThe final a part of the video explains a historical past of CineForm codec to make a ultimate declare. The CineForm video codec (developed between 2001 and 2002 by David Newman) is a wavelet compression video codec additionally broadly accessible in 8-bit or 10-bit YUV, or 12-bit RGB/RGBA (CineForm HD).Merely put, CineForm is an adaptation of JPEG 2000 format, however with a concentrate on pace (of video modifying). CineForm is manner much less computing-intensive than JPEG 2000 – 8x to 10x quicker to edit with the file sizes being solely 8-10% bigger than JPEG 2000. CineForm achieved it by selecting a Huffman methodology of uncooked knowledge compression.Later in 2005, CineForm RAW was launched to supply substantial compression immediately from CFA Bayer picture sensor knowledge. This codec was then used within the SiliconImaging SI-2K digicam that was capable of report visually lossless uncooked Bayer knowledge in a 10-bit log. In keeping with Jinni.Tech, the CineForm RAW was developed and launched earlier than 2005, so earlier than RED even existed as a mission (which was since December 2005).The SI-2K digicam that recorded CineForm RAW. Supply: Jinni.TechThe level of speaking in regards to the CineForm RAW codec was for Jinni.Tech to show his declare that it’s mainly the identical expertise that RED later bought patented with REDCODE with solely a slight distinction within the GAS (inexperienced common subtraction).Conclusion & OpinionPlease take into account that this text incorporates lots of the claims from the Jinni-Tech video and these will not be the opinions of the article’s writer or CineD as an organization. Whereas the video does increase some fascinating matters for dialogue, it’s all the time essential to listen to either side of the story earlier than making a judgment.RED modified their methods over the previous few years and their latest cameras (Komodo and the DSMC3 line) now use “off-the-shelf” media. It’s unclear how a lot this modification was pushed by Jinni.Tech’s REDMAG movies from 2019. Right this moment, there are nonetheless “RED-approved” reminiscence playing cards, however that is extra of a advice. Many different non-approved CFexpress and CFast playing cards work too. I feel this was constructive progress for filmmakers as a complete. Truthfully, I feel the RED Komodo, as an example, is a really moderately priced cinema digicam given the specs (particularly due to the worldwide shutter sensor design). Moreover, not like with earlier RED cameras, clients now not want to speculate 1000’s of {dollars} for equipment to have a ready-to-shoot digicam bundle and that’s good. Additionally the RED V-Raptor 8K is a outstanding digicam with a outstanding dynamic vary contemplating its value and dimension, as we uncovered in our standardized Lab Check solely two months in the past.Personally, I might like to see extra digicam producers be capable to embrace compressed uncooked codecs of their cameras and never be restricted by RED’s patent. On the opposite aspect, proudly owning a patent is a crucial asset for each firm and RED obtained it legally in 2007. It’s a pity, nonetheless, that this explicit patent limits entry to raised video codecs for corporations corresponding to DJI, Nikon, Kinefinity, and others. Nikon vs. RED would possibly change the gameWe would possibly discover out within the not-too-distant future if the patent holds: After RED sued Nikon for utilizing an inner compressed uncooked codec of their flagship Z 9 digicam, Nikon countersued RED, mainly saying that their uncooked patents will not be enforceable as a result of they missed to speak in confidence to the patent workplace that they made their uncooked compression expertise already widespread data earlier than the appliance. Jury trial is about for January 2024, so this may take some time till we all know extra – within the meantime, Nikon Z 9 customers can proceed to make use of inner compressed uncooked.
