    mnewxcv reacted to KnightsFan in NX500 4K Rolling Shutter?   
    @mnewxcv
    Sensors usually have a number of different readout modes with different resolutions, noise levels, and RS values. Samsung might be using a different readout method for HD on the NX1 and the NX500. 120fps  requires a readout under 8.333ms, and Samsung might have just made all HD framerates on the NX1 use that same 7.9ms mode, for whatever reason. The NX500 can't do 120, so there's no reason to use that readout mode at all.
    BUT...
    Tbh I am not sure whether the DVXuser test measured the NX1 HD in all frame rates. We'd have to dig through the thread to find out. It's possible that the NX1 has 7.9ms in 1080p120, and 20ms in 1080p30.

    so it would seem you were pretty much on the money with your estimate. That is the only info I have been able to find on nx500 rolling shutter, though interesting that the 2.5k is so low, and also that the 1080p is significantly worse than the nx1 (7.9ms according to this thread: http://www.dvxuser.com/V6/showthread.php?303559-Measuring-rolling-shutter-put-a-number-on-this-issue! )

    thanks for the question! I second it. Also, how is the 2.5k quality, bitrate and codec quality for grading? love the robust panasonic codecs. the 8bit 100mbit hd codec of the gh4 is really cool.
    interested, if nx500 would offer this, paired with an awesome readout speed, tiny rolling shutter. give me gh3 quality with a 7ms readout. Thank you!

    I haven't seen anything specifically about rolling shutter on the NX500. So take this with a grain of salt...
    The NX500 4K is a 1:1 crop, unlike the NX1's full pixel readout. Rolling shutter is likely proportional to the crop size, since it's the same sensor. That would estimate to be ~19.3ms for UHD. (NX1 reads 3650 vertical lines in 32.6ms, NX500 reads 2160 vertical lines. 2160/3650 * 32.6 = 19.3).

    I remember reading that the 4K of the NX500 had superior rolling shutter to the NX1, and I believe to other cameras as well. I cannot find a thread or the source of this information though. Can anyone cite a scientific source (controlled test on a camera site) that reveals this? I know the 1080p and 2.5k footage is marginally worse than the NX1 1080p.

    mnewxcv reacted to musaire in NX1 panning super jittery   
    Hi everyone! I am still using NX1 as well.
    Jitter and turning green?
    I have experienced both. When filming in nature I started noticing that when turning the camera towards greenery, the pic got more magenta-ish when WB was locked. Opposite happens too. This made me realize Samsung had all figured out correctly; if we lock the color on the Kelvin blue-yellow axis, it can still freely move on the tint axis. So it is not completely locked, obviously. The Kelvin is locked, tint is automatic. Very logical of Samsung ? ? .  All color is locked when all axes are locked in custom color or presets.

    Jitter. I had always jitter when editing the H265 footage directly in Sony Vegas Pro, and the jitter even did remain on YouTube. With every camera setting and render settings I used.
    The jitter went away once I started to use RockyMountains Movie Converter and edited with anything but H265. I am still wondering what is the reason, but probably it has something to do with H265 and how players and NLEs handle it.

    I’m not using the shutter priority mode, sorry that was possibly confusing. The S or Samsung special mode on the dial, it has a whole bunch of speciality shot options like the light trace and the baseball swing detection.

    mnewxcv reacted to KnightsFan in NX1 Extended Dynamic Range? New Settings.   
    I thought I addressed that with my theory that the RGB slider operates on a linear image before the gamma curve is applied, which explains why it clips almost immediately in Gamma DR but not in Gamma Normal or C. But I expect that the RGB slider multiplies shadows as well, so not sure how much usable DR you would gain as it basically just lowers exposure overall. Certainly something to test if you want to follow the rabbit hole!
    I think the only way we could meaningfully get a DR increase is if we could apply the RGB multiplier to the top half of values, but not the bottom. Most of what I've seen so far, both with my tests and yours, is really minimal, if at all present.
    As far as I can tell, MP doesn't really add DR with a positive value, it just raises the blacks up a bit. At most you gain back a little bit of noise. With negative values yeah, it seems to lose shadow detail. So I usually leave it at 0.
    Haha yeah, I just spent a good part of my day on this, and the funny part is I doubt I'll ever even use my NX1 for a project again! For my next project we're using the director's XT3. I did shoot a big project on my NX1 using RGB boost last year, which I might detail here once it's released. For me it was all about finding a general setting that worked for everything, since I wasn't going to fiddle with settings on set even if I knew wanted. So I used RGB values near 1.99 in Gamma DR, built some LUTs that worked with those settings, and left it that way. Worked pretty well in hindsight.

    I am going to revisit this using negative values (<1.00) for each color again to see where it starts to fall apart and lose DR.

    I can confirm that turning OLED Color on/off creates a visible difference when shooting a colorchecker. Attached a photo of each. Looks like a bit higher saturation overall, but it is also not linearly increased for each color. Rather, blues seem to be a bit higher in saturation with OLED color on, and the magenta trace seems to pull true to magenta, while the magenta trace pulls slightly to the blue side of magenta with OLED color off. Also, my wallpaper, which I consider to be in the white family but containing some color looks much more yellow/warmer with OLED color on. However, the white squares on the color checker are almost identical between on and off, so white balance isn't really affected directly.
