    Marco Tecno reacted to Andrew Reid in Panasonic GH5 10bit vs 8bit   
    Well people with 8bit displays have been raving about 10bit for ages now so it's time to find out the truth
    I can certainly see a difference with 14bit RAW but I'm not sure about 10bit vs 8bit YUV
    JPEGs are 8bit, nobody complains
    That said, the whole image processor seems to have had a hefty upgrade in the GH5 and I am still expecting good things from it

    Well the differences in that video are so subtle I can't even see any
    The colours coming off the sensor though look fantastic, a big improvement in skintones for Panasonic this time round
    Is that the 180fps at the end? they didn't bother to label it... If it is 180fps that looksimproved over the pre-production model footage I saw before... not a hint of moire and very nice detail
    But the 10bit needs some proper evaluation once this marketing bullshit period is over, me thinks

    Does ANYBODY have a proper comparison video up yet?
    What about a direct split screen comparison between the 10bit and 8bit mode? And does 10bit make a difference in the grade?
    Aside from Neumann all the coverage this time has been total lightweight fluff. Really lazy. Quickly punted out, to collect hits. I honestly don't think any of the testers have put more than 5 minutes of work per video into what they have done. Can't find anything comprehensive at all.
    They really should have given me a camera, the retards

    My recommendations, as others have already stated:
    d750 - the body is dropping in price, keep an eye out for a deal. Full frame, super DR and color edge over a7s, but soft 1080p.
    nx1 - jack up the bitrate with the hack, invest in Luca's speed booster, and keep that ISO as low as possible...you have a excellent 120p performer. Best 120p full frame for the price (maybe the only). Great color and sharpness, lackluster DR and strange highlight/black levels when grading if you ever miss your mark on exposure.
    a7s - keep it in crop mode and speedboost. Best low light, great sharpness, DR and highlight roll off but, imo, terrible white balance and strange colors. Compression isn't the best either
    a5100 - super cheap, speed boost it and it's quite comparable to the a7s, a tad bit softer, a bit less dr and a bit more macroblocking/artifacts but for the price...
     
    And hear me out
    Bmmcc - if you can live with near apsc crop instead of full frame, bmmcc speedboosted would probably yield the most beautiful results. But that's subjective, as I value color information a bit more than compressed 60p.
     
    buy an rx100 iv as b cam for superior slow mo of any of the cams. Excellent sensor readout and result for a compressed image. 1 inch sensor though.

    I have been working with a digital logic analyzer and an Arduino nano.  Via this setup I can set the aperture and move the focus to min and max so far.  So the setup is
    For gathering data: Canon Camera + EF extension tube with AF contacts + lens, I have wired the extension tube to sample the data via a USB digital logic anlyzer. 
    For testing my control: Arduino Nano + EF extension tube with AF contacts + lens (no body for now).  So the aperture and focus max and min are working as controlled by the nano. 
    Next step: NX camera + NX extension tube with AF contacts + Arduino Nano  and use the digital logic analyzer to find the focus commands from the camera, also spoof the lens data.  Here is where ihkim's work will be a big help with the lens initialisation, to hopefully successfully spoof the lens in a way the camera accepts. 
    Final case: NX camera signal to contacts on close end EF -> NX adapter, these wired to the nano, then from the nano to the contacts on the other side of the adapter, then to the lens.  Then replace the adapter with wired NX-L for focal reduction. 
    Stabilization seems to work automatically for the lenses I've tried, but I think the EF-M mount lenses don't have physical switches, but these are not among the lenses we're adapting. 
    My 10k offer still stands for anyone that can provide native-like camera driven AF.  The Apurture DEC does not do this, as I understand it doesn't listen to the camera half at all, in which case I'm only a few buttons away from doing the same with the nano (add button to repeat change focus command one way, another the other way, same for aperture).  Wifi would be a bunch of work though, but while nice it isn't on my own wish list.  The nano will allow more programmatic control, 2,3,4, etc... focus locations could be toggled, it's mostly a matter of adding physical inputs and writing logic into the nano code to handle them.  As I look back to your image of the upcoming system, the contacts are going to go just from the Apurture to the lens, I also need to get to the camera contacts somehow.  What I need is camera -> Apurture and Apurture -> lens (but with my nano instead of the Apurture).  With the current NX-L design I'm not sure how to get at the camera contacts, running wires even with a hole drilled through isn't great because of the rotating design, so they can be stressed or break if it rotates too far.  Solutions that come to mind would complicate the design quite a bit further (e.g. concentric rings for each contact on that part that rotates). 
    That would be great, can you PM me the address, I didn't keep the packaging they arrived in so I lost the return address.

    Hey IKSLIM, had I needed to buy a new one for this update I probably would have sold you one, but Luca's kind offer is keeping both with me for now.  Upon closer inspection the  Apurture design version doesn't have the contacts I need camera side, so unfortunately you're out of luck unless I end up acquiring a 3rd one.

    I hate to be "the NX1 guy" in this thread ha (I'm actually suprised none of the usual suspects have piped up yet)... But it might be worth looking into the NX1, or the even cheaper NX500 for that matter, both produce lovely, sharp 60p (and gorgeous 120p as well!) with minimal moire/aliasing, crazy low rolling shutter, and decent enough lowlight performance with a fast lens, which you're obviously interested in, i.e. shallow dof, or you wouldn't care so much about sensor size. I have no idea what they'd go for down under, but there are lots of gently used ones around for pennies. Our very own forum member Lucabutera is selling some awesome NX-L speedboosters that he has crafted as well, I have one, which gives the camera about a 1.1x crop. 
    Seems like it'd fit your parameters pretty spectacularly. Best of luck!

    Hello ttbek, how are you?
    You must keep up to date, if you come on the forum every month you will always find new surprises.
    The next series will predisposition of electrical contacts.
    I will make a version NXL mute and a version with electronic controls.
    Currently, for practical reasons, it is being tested, the Aputure Dec control that allows:
    1) iris control Canon lenses;
    2) Stabilizer Canon lenses;
    3) WiFi Control focus;
    4) recording 2 subjects for quick changes of focus.
    Currently I started the study of a smart autofocus system, but this will take a little time.
    How can you help me? Been programming? You want to finance my project? Or both?
    P.S. If you ship me the NXL I can update it for telephoto compatibility.

    Hello Ikslim, I build them in sets of 10 pieces at a time.
    Next week I will send the first 10 already sold, for the next production will have to wait a month, but it will have some constructive improvements and also the predisposition for electrical controls.

    Marco Tecno reacted to Drew Veeneman in Production Dairy - Using Hacked NX1 and NX500 on YouTube Channel   
    Hey gang, got another Carry Trainer Episode! Tested Slow Mo on the NX1 for a Gun Review:
    We had a variety of cameras for this video. For the main interview style talking head footage, I used my dual camera setup on a tripod. The tighter shot is the BMCC 2.5 with the 50mm Super Takumar F/1.4 and the Mitakon Lens Turbo II adapter(this speed booster is new, not in previous videos). The wider shot is the NX1 with the Super Takumar 35mm F/2.0... this was used for the close-up cutaway shots of the gun as well. (The corner sharpness sucks on this 35mm lens. I made it look good, but I need to swap it out for the F/3.5 Super Tak version.)
    The opening of the video has hi-speed footage from the NX1, recorded at the 1080p 120 fps setting(really 119.98 fps). In post while trans-coding, I stretched the footage out 500%, which perfectly fits 23.976. 23.976 is the standard 24 fps frame rate commonly used, and the base frame rate for Carry Trainer videos. Note, there is raw slow motion footage in the Bloopers at the end of the video (Go to 13:28) if your interested. In the bloopers it's literally straight out of camera with no adjustments other than re-timing it to 23.976.
    I wasn't present when the range footage was shot. That was recorded on Mickey's fancy Samsung cell phone, which amazingly recorders 4K... BUT AT 18 FPS. Lol. I just loaded this into DaVinci resolve and flipped the Optical Flow frame blending switch.That did a good enough job.
    Technical Notes: On the NX1 audio dropped out completely from one of the interview clips. For me it didn't matter because I wasn't using it(had a Tascam external recorder on the Lav), but I thought I'd report the glitch. My first clue was that the audio levels weren't moving at all while it was recording. The NX1 did fine recording after that.

    Marco Tecno reacted to Axel in Comforming fps for slowmotion. I'm very confused   
    Why not? But not necessary. In Premiere, you can conform all clips in one sweep in the project window. In FCP X, you can assign a keyboard shortcut for Automatic Speed to conform one or multiple selected clips. I have ctrl+cmd+r (because there already are retiming shortcuts). This is for 30-60 fps. Usually higher framerates are flagged as slomos anyway by the camera.

    Yes. Then he should better have shot at the project framerate in the first place.
    Or shouldn't he ???
    Because 30p wouldn't spontaneously be perceived as slow motion, but as "movie-time". Gravity, importance. It's an editing tool also. If someone backswings to build up momentum for a strike, it's better to accentuate the movement (a tiny, not too obvious time ramp) or else the whole action may look lame and speeded-up (or is it sped-up?). Also, for smooth camera movements, pans, slider- or gimbal shots, 30p can be appropriate. Watch this:
     
    Thanks a lot. Framerate conforming works differently in FCP X (you select the clips in the timeline, then you apply Automatic Speed from the retiming dialog, FCP X adjusts the audio's pitch per default). To render all frame rate changes with optical flow on export, you have to edit (click the said boxes) and save the export module in Compressor. I didn't know.

    The guy in your video knows nothing. Here is how you interpret 30p "as" 24p (or whatever your timeline is set to), and every frame will be played back without stuttering.

    I think so too, but I've never heard of 500Mbit / s with external recorder.
    I have provided only official information, this can be useful to OttoK or Kino for Hack development.
    There might be a flaw in the system which limits the data output from HDMI port but no impediments on wifi.
    I think that on this point it is worth investigating.

    Dynamic range is the NX1 weak point, specially the highlights, you really need to preserve as much highlights as possible or else the image will become very digital. However, having tried a lot of "prosumer" cameras (nothing fancy, just Canons, Nikons, Sonys, Panasonic etc) this is yet my favorite camera...even against my new sony a7sII...And im not just talking about the experience, but the image itself, samsung surprises me everytime I load my sd cards in my computer, and with the sony, only after quite a bit of tweaking the image starts to look good. Maybe because im still not used to this camera, but the NX1 was an amazing surprise, and it was worth every single penny I payed for it.

    Hello everyone, these days I started working in a new project for the construction of an smart adapter, by accident I discovered that the NX1 offers 2.4GHz and 5GHz Wi-Fi wireless networking connectivity compatible with IEEE 802.11b/g/n, as well as the faster 802.11ac standard which has enough bandwidth to stream 4K video wirelessly over 500Mbit/s.
    Can anyone verify this?

Lenses: Samsung 16-50 S, Rokinon 12mm and 85mm, plus some lensbaby. I used a couple LUTS by luts.iwltbap.com and FilmConvert in post. Filmed in 4K converted to ProRes for editing in Premiere. Yes, I know Premiere supports H.265, but I've had nothing but problems with H.265 files since the last update. Exported to 1080.
