GH4 4K Panasonic video camera, official topic

    What would Panasonic be thinking here??? Do you guys believe they just shot themselves in the foot? Did they not think about the competition breathing down their necks?

    How about to stop discussing seriously prices made up by shops to get preorders? For money people do nasty things.

    Next up. Black Magic camera exist in the amount of few cameras sent to leading resources for now. It uses EF mount (very bad decision for owners of many lenses). It has some issues with sensor as BM rushed to use any suitable and available (to them) sensor at the time to get 4K. It is camera with bad screen, very few features, without EVF, non functioning AF (if just barely). And made for very small niche, yet with big amount of flame.

    If the price for the camera and the DMW-YAGH add-on proves to be correct, that's about $800 more for the complete package than the Blackmagic Designs 4k Cinema Camera with internal 4k 10 bit recording. That's especially if you need the "YAGH" for 4k out to a recorder.

    No links to shops who just want preorders here. Use your head, please.

    Not Voldemort fantasies, Lol!!!!!

    @AdamT

    I am ok to discuss Panasonic statements, actual tests and such. Not Voldemort fantasies.

  • killagramkillagram

    I hope Vitaliy is right too but there's more evidence stacking up against it. Convergent Design is stating a "popular codec" (ProRes?) will be available for 4K 10-bit 4:2:2 via the YAGH accessory:

    Just wanted to note that with the addition of the YAGH accessory base to the GH4, the Odyssey7Q will be able to record 4K 10-bit 4:2:2 video in a high quality "popular codec".

    I'm trying to confirm that the signal isn't acquirable via micro HDMI.

  • AdamTAdamT

    @VK Hope you're right. Seems that Voldemort was confused, too:

    "1. Does the GH4 output 4K over the micro-HDMI port?

    When the camera is set to record in 4K internally the onboard HDMI output is down-converted automatically to 1080p. In playback mode the HDMI output is 4K capable (relaying the 8bit 4:2:0 footage from SD card). Only the DMW-YAGH add-on base can output 4K (uncompressed, 10bit 4:2:2) from the GH4. However the micro-HDMI port is 8bit / 10bit switchable and can deliver impressive 1080p in 10bit 4:2:2 format, uncompressed to an external recorder."

  • Vitaliy_KiselevVitaliy_Kiselev

    Could just be awkward phrasing but it sounds like 4K is downsampled to 1080p when recording via micro-HDMI.

    No, it means that camera check display EDID and if It does not support 4K makes downsample.

  • AdamTAdamT

    @Aria The reason I think it's unclear whether the micro-HDMI will record out 4K is this paragraph from Panasonic's GH4 specifications page:

    "MONITOR-THROUGH: 4:2:2 8-bit / 4:2:2 10-bit (When 4:2:2 10-bit mode is selected, it is not possible to record motion picture or still picture on the SD memory card in the camera unit.)/information display ON/OFF (selectable)/Automatic down-conversion (4K → 1080p only)"

    Could just be awkward phrasing but it sounds like 4K is downsampled to 1080p when recording via micro-HDMI.

    Now, we must remember that Rec. 2020's color points are for CONSUMER-END broadcast video, not necessarily commercial cinemas or professional post work. If you look at Rec. 709 and compare the two, it does look like Rec. 2020 is superior. Industry types seem to think so.

    But Rec. 2020 also includes high frame rates, higher bit depth, whole frame rates (24 fps rather than 23.97, etc.) and the like, so it definitely is a couple of steps in the right direction. Now, will 4k displays, 4k discs, and other electronics have it included soon? HDMI specs. will have to be improved since 2.0 does not accept all of the ITU profiles.

  • JDNJDN

    @driftwood, any more details on color/picture profiles would be great, in particular how log-ish it can get (without going too far down that road of course because true log with 8 bit 420 is dangerous).

  • crisvplcrisvpl

    atomos ninja 2 is 1080 60i only... and Odysse 7 is indeed 60p. but on hdmi is only 422 8 bit. on SDI only is 10 bit. is it posible to use a HDMI to SDI converter to have 10 bit? in order to use it with BMPCC for instance...

  • jakepowelljakepowell

    @Jean71 the problem seems to be piss poor lighting if you ask me on the interiors

  • TomasoTomaso

    @crisvpl as I understad it both Atoms Ninja 2 and Odyssey7 do. http://www.convergent-design.com/Products/Odyssey7.aspx#Specs-21

  • crisvplcrisvpl

    is there any external HDMI recorder that can do 1080 60p? or somebody will release it soon?...

  • Jean71Jean71

    I bet there were no colorist, and i see the master is 2k (probably they shoot in 2k). An Alexa would had be much better, especially for a master DP like Guarnieri and an high seven figures of euro production.

    Anyway, to stay in topic, i think one reason could be that nobody around there even knew if they used Rec 709 or Rec 2020.

  • RikerRiker

    @igorek7 : i know i know i was showcasing my immense comedic talents :D

    This italian trailer looks professional but too "digital" for my taste...

    But can't say this trailer shows anything spectacular given that it's a 30,000 $ camera...I think with fair budget (basically with enough money to spend on lighting) you could pull similar results with GH...

  • Jean71Jean71

    Nope, but i see here Sony F55 with Rec. 2020 color looking like a telenovelas (in interiors), and the DP made some very good movies in his carreer. Average people at cinema will not see the difference, but i find this photography terrible.

  • LongJohnSilverLongJohnSilver

    @jean71 did you work on this?

  • Jean71Jean71

    @Vitaliy_Kiselev

    "Few things to understand. Rec. 2020 video will be always INFERIOR to usual one."

    +1 on this, and i'm posting an italian movie, shot with Sony F55, and some millions euro budget, by famous italian actor-director. Tell me what you think about these images...

    Cinematographer Ennio Guarnieri did some Fellini's movies, and other movies with great photography, so we are not speaking about an amateur.

    @Riker Are you asking about the AJA Ki Pro Quad 4K/QuadHD/2K/HD Solid State Recorder?

  • andrevanberloandrevanberlo

    Clearly some things aren't quite clear yet :-)

    HDMI out says 8bit or 10bit, perhaps 10 bit 1080p and 8 bit 4K?

    The main thing is people are disappointed about the price of the brick but when you look at the specs of the cam only, EVEN if it doesn't have 10bit 4K on that HDMI out, those specs are pretty impressive and much better than the competition, especially considering the price! I do think that if that brick is $2K and you really want 4K your best bet is BMC4K. Hopefully they'll be releasing an active m43 version of the BMC4K!

    In any case, just for the body, €1299 excl VAT seems very reasonable to me but lets await the tests first. (coming in may 2014)

  • AndySAndyS

    Yep.

    Every rig must have one.

    LOL

  • RikerRiker

    is that a POS terminal on that rig?

  • LongJohnSilverLongJohnSilver

    C'mon guys I'm a beginner but it's clear that crap doesn't depends on the brick.

    If you want continue with this bashing just buy another camera.
