    as I've found lower contrast to be more beneficial to a compressed image, that's what I've tested the most, and has really been the source of most of my gripes with the camera. The ability to lower saturation hasn't seem to yield many benefits in regards to post work, so I've only tried lowering it maybe to -5 at the most extreme, and I didn't see much benefit so I usually leave saturation at 0 now.
    With -5 contrast, 0-255, -10 sharpness and 0 saturation I've found the least amount of negative effects on the image, while gaining the most extra latitude. I have not found gammaDR to yield particularly better results (in regards to grading latitude).

    I think it depends on everyone's taste - someone prefers dynamic range (and more filmic?), someone likes richer and more accurate colours. I have almost same settings as Casey... I did not make any scientific tests but my opinion is that (with this limited bitrate and 8bit codec) it is best solution to get best picture straight out of camera. But please - let's focus on hacking of NX1 in this thread... :-)

    If raw video gets unleashed through hacking, then all these questions will become 'the past'. Consider this: nx1 does 1) full sensor readout up to 60fps, then 2) scales it to 4k or 2k, then 3) encodes it in h.265 in real time.
    Now...think about jumping steps 2 and 3 and just saving the raw sampled 6.5k image to sd card. Even if that were 12bit instead of 14, even if 24/25fps instead of 30/60, even if only for few minutes, this would be the greatest achievement ever in a sub 1000$ camera.
     
    I would buy a couple of spare bodies if this ever happens.

    It's magic!
    No, its the Megabyte (MB) and a Megabit (Mb) confusion:
    https://opensignal.com/knowledgebase/the-difference-between-megabyte-and-megabit.php
    https://www.google.de/search?q=megabyte+megabit+converter&gws_rd=cr&ei=463ZVumTOMb36ASKwp6wBg
    The NX1 writes with 80 Mb/s and thats 10 MB/s
    so possible is 60 MB and that's a 480 Mb Bitrate for the movie size.
     
    Edit: But the Size of one 6.5k RAW-Picture is round about:
    3:2-Format: 6.840 x 4.320 = 31,1 MB
    6.840 x 3.648 = 26,2 MB * 24 Pics/s = holy s... that's impossibel!
     
    But UHD with 400 to 480 Mbit/s vs. the original NX1 80 Mbit/s is a really heavy upgrade ... with 10 bit instead the 8 bit, i think it's a big thing.

    The NX1 is certainly under consideration.
    We almost did it last year, and then Samsung started pulling that camera from the shelves. 
    It isn't sold in these parts anymore.
     
    This is in discussion, but I can't promise anything at this stage.
    We've had quite a few requests for this camera in the last week so hopefully we can push that through.

    kidzrevil reacted to Ed_David in Follow up to B&H - Workers Unionize   
    Well said, Henry, also just found out you are head of PR at the audio department, which I love there.  So your opinion on civil and legal matters related to B&H is probably not as inclined to the data and official stance of the company, which is fine - all of this is probably private information as of now.  I know how much companies hate unions as well.  And how unions can play really dirty.  But if the NYTimes and Al Jezera both run stories on it, I think there must be some validity to the claims.
    Plus that B&H in 2007 paid a $4.3 million dollar settlement to unfair wage page to Latino employees, again scales me towards believing the first-hand accounts of the workers and their lawyers.
    Also it's possible with your photos that yes it does look really clean - cleaner than the studio I work above - the clean up was done after complaints and hints of unionization.  
    And lastly, I wonder, why is employees unionizing ever a bad thing?  Except to the corporation?
    Well finally, seems like according to the NYTimes, there were two seperate instances of workers signing documentation in English they couldn't read that signed away their rights to medical care reembursement.
     
    NYTIMES
    Martin Hernandez was moving heavy boxes of merchandise at a Brooklyn warehouse belonging to the electronics superstore B&H Photo Video in late August, he said, when he felt a sudden stab of pain in his left leg.
    “I felt my knee crack, and I just couldn’t get up,” he said on Tuesday, through a Spanish-English interpreter. “The pain was so intense, I couldn’t feel my foot.”
    Mr. Hernandez, 48, said he had been taken by ambulance to the Brooklyn Hospital Center. He eventually learned he had a damaged ligament, and has not worked or received a paycheck since the injury. He said his meager savings were nearly exhausted.
     
    Or of these two employees given documents to sign in English that said B&H was not responsible for their on-site Health issue:
    Ms. Mazzocchi also dropped off a letter addressed to Mr. Schreiber and Mr. Goldstein, asking that they act on complaints that employees had been subject to discrimination because they are Hispanic, had been pressured by managers to sign English-language forms releasing the company from medical claims and had been forced to work long hours in warehouses where emergency exits were blocked and noxious dust appeared to cause rashes and nosebleeds. She said that if she and other lawyers did not receive a favorable reply by Oct. 20, they would file 180 separate claims with the E.E.O.C.
    Mahoma Lopez, a co-director of the Laundry Workers Center, an advocacy group that works mainly with low-income immigrant workers, said they had begun meeting last year with B&H warehouse employees. The center’s organizers held workshops in which they instructed workers about their legal rights, he said, and explained that they would have more strength working together than they would as individuals. Eventually, Mr. Lopez said, the center helped the warehouse employees contact the Steelworkers union.
    One of the workers who said he had wanted to be represented by United Steelworkers was Mario Baten, 29, who said he had worked for B&H for six years but had temporarily lost his job in 2010 after he collapsed at work. Mr. Baten, who said he had suffered for years from cancer, said through a Spanish-English interpreter he had awoken in a hospital and received documents that had been delivered to him by a B&H manager.
    “He sent papers in English that I had to sign,” he said. “I didn’t know what they were saying.”
    In the main B&H warehouse located in Brooklyn’s Navy Yard, the walls and ceilings are insulated with fiberglass that fills the air and flecks off onto the worker’s skin, causing rashes, respiration problems and daily nosebleeds, employees say. Inside a second warehouse, on Evergreen Avenue in Brooklyn, employees say they have worked amid asbestos-insulated tubing. “They would tell us to clean the tubes,” recalled maintenance worker Miguel Angel Muñoz Meneses, “but nobody wanted to touch them.”
    The men, many of whom are undocumented, testify of suffering from kidney stones, dizziness and fainting after being denied access to water or bathroom breaks. They say there is often a lack of basic safety equipment. “If we ask for gloves, they answer that they do not have gloves, because gloves are too expensive,” said Isaias Rojas, a B&H employee.
    One man reported he was badly cut while lifting boxes, and the managers refused to call an ambulance, instead advising him to simply wait until the bleeding stopped. Another said a manager threw hot water on him and slapped his face. Others report those who complain are fired or threatened with deportation.
    “They treat us as if we were animals,” Florencio Salgado said. “We are involved in this because we are tired of being abused.”
    For many of the men, the most egregious offense occurred on Sept. 5, 2014, when two tractor trailers parked adjacent to the Navy Yard warehouse burst into flames, sending clouds of black smoke into the shipping and receiving section as the workers were inside.
    Silverio Cano Alberto, who has worked for B&H for seven years, said he was on the second floor as the flames licked the outside of the warehouse.
    “There was smoke and yelling and no one, including the manager, paid any attention,” he said. “Finally, they told us we could leave, but we each had to pass through the metal detectors, which took about a half hour. When I got outside, the parking lot was filled with firemen and police. Imagine — if the fire had spread, we would never have all made it out.”
    Stephanie Luce, a professor of labor studies at the Murphy Institute at the City University of New York, said that, if verified, these allegations would constitute violations of the “highest level of basic rights.”
      were they verified?  is there a civil suit pending?  or was it settled privately? Florencio Salgado, 37. Salgado has been employed in the B&H warehouse for 10 years, working long hours to support his parents in Mexico. “They are exploiting us," he said. "They are 'juicing us' like a fruit. Once they take all the juice from us then we will be thrown away because we are going to be good for nothing.”Jonah Markowitz“These are very serious,” Luce said. “That's one of the main things that happening in places like Bangladesh, where there have been fires and buildings have collapsed, and workers can't escape.”
    B&H declined to comment on any of the specific allegations, including the handling of the 2014 fire.

    Since Mr. Jones brought it up - 
    As a follow-up story to B&H Photo Video and Worker Abuses - they have unionized.  
    And this is partly because of people like you and me:
    "The workers received additional support on Oct. 22, when a coalition of photography and video professionals launched an open letter to B&H management, calling on the company to end the hazardous working conditions and discriminatory practices. They also called on the company to negotiate a fair labor contract. Within a week more than 1,000 signatures from artists, journalists, gallerists, educators, students and photo technicians were obtained.
    “We welcome the workers at B&H to the USW and look forward to addressing their concerns with the company at the bargaining table,” said Shinn."
    http://www.usw.org/news/media-center/releases/2015/bh-photo-warehouse-employees-vote-to-join-usw-union
    This is an example of social media activism being successful.  The employees now have collective bargaining powers.

    They're good! Sharp. A bit smoother in contrast than Zeiss, but also more sterile. Should resolve just fine on the NX1 sensor, depending what's in the set. Just expect to use them one stop down from max aperture; vintage lenses with uncoated rear elements tend to glow a bit wide open, which the NX1 hates.

    For anyone who has not seen the effect for themselves - doubling the bit-rate will blow you away. 

    The Panasonic GH2 had even more issues with the image quality than the NX1 does, and with the 150mbps hack the difference is HUGE.
    EVERYTHING is better and all the problems of mush in the image and macro-blocking and colors breaking up all just vanished.

    Really the only reason I don't use my GH2's as 'A' cameras is because their older design has less dynamic range...maybe 9-stops. 9.5 if your exposure is absolutely perfect.

    If we were to double the bit-rate on the NX1 even the Noise Reduction and Sharpening would be FAR less of a problem because they would both be working with so much more image data.

    If I remember correctly from working with GH3 footage the banding was nowhere near as bad as on the Samsung NX1 of course Samsung fixed a lot of the shitty colour bleeding and terrible banding issues with the newest firmwares but the banding still persists, its there if you pay attention and you definitely will see it when you work with the files.
    I can apply the LOG profile from EOSHD to the NX1 footage with the proper settings in place, if I push colours too much I see banding, I have some GH4 footage I shot before I sold it duo to the low light performance being unsatisfying, I can push the colours quite extreme without seeing any form of banding, even in the 1080p footage. Obviously the NX1 has way better colour range than the GH4 with Cine-D and I sadly its almost a year and half since I sold the GH4 and back then we had no idea there was an actual LOG profile coming for it at all, not even the news about the beta LOG being worked at. 
    Its pretty clear its the HEVC codec doing it, I have reproduced some of the nastiness of the HEVC by using clean high bit depth images with gradients applied and noise in sections to see what the codec does to it, indeed the codec does cause banding at 8bit output, it also smoothens out noise in low detailed areas, I further checked with a still picture shot at 1600 ISO with some fine grains, again I see the same the codec smoothens out the flat areas, in high detailed areas it leaves but every area that has no details the codec smooths out, the earlier versions of HEVC were terrible at detecting detailed areas its gotten better. I will just assume here the NX1 uses the earlier version of the HEVC codec because its clearly destroying details in out of focus dark areas were the codec is struggling to detect details. It gets worse when you lower the video bitrate as well of course the in-camera noise reduction in video does not help at all just makes the issue far worse than it should be. 
    Its managable but if we can turn off noise reduction in video, that would be a life saver for all of us because many of us does not have the luxury of light to shoot one or two stops over. Some of us are forced to shot stops under, its either that or very high ISO and we all know what happens then...

    We need to disable the noise reduction in video, its killing me inside literally. You know its sad when the Panasonic FZ-1000 has better noise grain in 4k video than the NX1 which is just muffled mosquito noise, I had a look but could not find anything. Does anyone have any idea? 
    I know the HEVC codec deals with fine grain texture poorly specially in my personal tests from converting Blu-Ray films to HEVC. 
    But the NX1 has a nasty noise reduction in video which you cannot turn off and quite frankly its destroying details very badly.

    Hi,
    A nice breakthrough in hacking NX500 (and possibly NX1 - could someone try and report back?).
    So, TLDR version first: I'm able to run a shell script off the SD card without hacking the firmware (and some other stuff). This is just a very modest start, now we need to do everything else. That said, this is a useful start as we can now play around without bricking cameras.
    That was the moderately good news, the moderately bad news is that I'm absolutely swamped by work related stuff next few weeks.
    Now for longer version:
    First a small "hack": If you want to take a screenshot of your camera screen put a file named save_screen_enable.txt in the SD card root and every time you press EV+OK a file named OSD####.jpg will be saved to SD card root. save_screen_enable.txt will contain the integer of next image id (as bytes, not text).
    Another small "hack": If you want to see how all the popups and notices look in all the languages (for any reson) put a file named qa.txt in the root of the SD card. When you power the camera on you will see a popup menu that enables you to access all the popups, etc, in camera (press up and down to change them, left and right to change the language). It's meant for quality assurance staff, but here it is.
    If you like scrolling through the popups - that's fine. Even better is that the camera app crashes on popup 188 (of 189, go figure) and produces a lot of detailed logs on the SD card. These logs are named timestamp_{log,a7_log,a9_crash,a9_dlog,a9_dmesg}.info
    If you take your sweet time analyzing these logs you will find that NX500 does not boot all that often - it hibernates and then wakes up when you power the camera on - cute - that's how it starts up in one second
    Also, some RAM information: Total RAM is 512MB, reserved (buffer?) is 380MB. It fits nicely with known buffer limitations. It also means it's very very difficult to extend it to anything larger (maybe by eliminating allshare app or similar but that would give us a frame or two in RAW at best - hardly worth it).
    How to run a shell script file:
    1. Put file named "info.tg" on the SD card root with contents "nx_cs.adj" and a newline
    2. Put file named "nx_cs.adj" (can use something else really) on the SD card root and put "shell script /mnt/mmc/test.sh" and a newline in it
    3. Put file named "test.sh" (or whatever you put up there) on SD card root and put whatever bash shell commands you want to in it. Word of caution - it's easy to make a mistake - start small and work carefully
    4. Put SD card in camera
    5. Camera to AUTO mode (IIRC it works in any mode but whatever, it's in AUTO in the Service Manual)
    6. Power on the camera and wait a bit (or a lot, it seems it's quite lazy with closing files and syncing, might do it for it by calling "sync" at the end)
    7. Power the camera off (and wait for blinking light to stop blinking if it's blinking)
    For example, if you put following in test.sh
    st > /mnt/mmc/test
    This is what you get on the output:
    usage: st [command] [param]
    Supported bult-in commands
        help        readl        writel        dump    
        gpio        hdmi        log        lcd    
        cap        pmu        clk        thread    
        key        firmware    util        app    
        leak        devman        stlcd        bat    
        rtc        tbm        micom        misc    
        oic        dvfs        adc    
    I put a "ls -laR / > /mnt/mmc/test" and it did list the whole filesystem including /proc /sys /dev etc. And /etc tar also works.
    I can see for example that every time process id 247 is given to /usr/apps/com.samsung.di-camera-app/bin/di-camera-app and it runs under root (almost everything does), dfmsd (that's the deamon that interprets commands in nx_cs.adj file that are read and sent by dfmstool - I will have to see what else I can do with it), /usr/apps/com.samsung.ap-setting-app/bin/ap-setting-app running with some access keys or hashed caller PIDs, etc, the works.
    Only two modules are loaded (exfat_fs and exfat_core) but I guess we could compile anything we need and enable it in the future (usb audio anybody?).
    That's it for now (and some time).
    Oh, yeah, the touch screen does not work with info.tg or info.tgw present on the SD card.
    Cheers,
    Otto

    Really this is all stuff you can do even just in Premiere or Resolve or FCPX.
    It just takes a lot of work because YOU must make a LOT of decisions about each and every clip in order to get these kinds of edits to work visually. This is why software really can't do it for you. By the time you've told it all the parameters you want it to follow for a particular pair of clips - you've basically completed the edit yourself already.
    However, depending on how you shoot the "frozen in space camera" effect, you may often need to use a tracker like in AE.
    Re-framing, key-frames, blur, and zooms/pans will do pretty much all of the MANY other types of edit-transitions featured in this piece.

    A lot of this relies on a very basic principle of editing - "line of sight".
    When you line up the main subjects of the clips that are drawing the eye to them, then there is less jarring movement of the viewer's eyes that is required in order to easily and quickly focus on the subject of the next clip.

    Yup.

    I'm currently just using Andrew's NX1 LOG converter and his whole recommended setup - no alterations. Then I add an Osiris or Canon/Arri LUT and I'm done. (or a few customized BMD LUTs I have.)

    After moving from Panasonics and Canons to Blackmagic RAW I'm just burnt out on battling compressed codecs and picture profiles and all the zillion possible settings.

    There are no "settings" on the Blackmagic cameras really. You shoot at the native ISO or 1-stop above or below pretty much only. The you just white balance and set your exposure and shoot. You either like how the camera looks or you don't. I absolutely frikkin' LOVE how the BMD cameras look so I'm DONE.

    That awesome Hong-Kong video that Dean posted a few pages back convinced me to try Andrew's package. I'm sold.
    It's really so good that I'm not interested in doing any further nit-picking. 
    I LIKE that look and it can cut with the BMD footage so I'm happy. It does what I need it to do, and it does it reliably.

    I suppose I would still be interested in other picture profiles or settings on the NX1 if it was my 'A' camera, but it's not. I need it to cut with the Blackmagics.
    Plus I just personally REALLY like the look it gives in general. 
    What a relief, ya know?
