GH4 4K Panasonic video camera, official topic

    I'd assumed that 720p would surpass the 1080's 96fps, but I've seen no mention of 720 overcranking at all. What am I missing?

  • Ian_TIan_T

    That's it...I'm getting one. It got @LPowell's blessings...I'm in.

  • DrDaveDrDave

    Like the pro features, was certainly hoping for 24 bit pcm. 16 bit pcm meh. Don't like the "Yuk"atan video, maybe they overdid the polarizing filter but there is something a little teaky about the color and the moiree on the parrot, along with the stairstepping, well, I will wait and see. It doesn't pop off the screen to me like the Sony but it has tons of great features.

    Not my opinion or statement ... it's one from one of the Panny reps explaining the feature of the camera. Stating that all bodies have that ability. Go argue with Panny ... I don't know at all, just had commented on what the Panny rep said in the video. And we'll all have to wait and see what the heck he meant, as I haven't a clue either.

    At long last, Panasonic has announced an upgrade to the AF100. While the GH4's 4K resolution is attracting the most media attention, it's the pro features that set this camera apart from the rest of Panasonic's G-series DSLR's::

    NTSC

    1920×1080, 59.94p, 200Mbps(ALL-Intra)/100Mbps(IPB)/50Mbps(IPB), LPCM

    1920×1080, 29.97p, 200Mbps(ALL-Intra)/100Mbps(IPB)/50Mbps(IPB), LPCM

    PAL

    1920×1080, 50.00p, 200Mbps(ALL-Intra)/100Mbps(IPB)/50Mbps(IPB), LPCM

    1920×1080, 25.00p, 200Mbps(ALL-Intra)/100Mbps(IPB)/50Mbps(IPB), LPCM

    Cinema

    1920×1080, 24.00p, 200Mbps(ALL-Intra)/100Mbps(IPB)/50Mbps(IPB), LPCM

    Video

    4:2:2 color - 10-bit precision in external streaming mode

    Selectable full-range/broadcast-safe luminance range

    Selectable Cinema gamma curves and pedestal black-level

    Variable frame rates up to 96fps slow-motion

    Full-size HDMI and BNC connectors on base unit

    Audio

    Powered full-size XLR connectors on base unit

    Physical audio source, level, and VU controls on base unit

    Synchronized 16-bit LPCM audio encoding

    Pro Features

    Focus peaking and zebras

    SMPTE time code with external sync via base unit

    Color bars and audio reference tone output

    Built-in wireless control via iPad/smartphone

    Weather and splash proof magnesium frame

    The only significant feature I see lacking is the AF100's built-in ND filters, which no one would expect in a DSLR camera anyway. Good job Panasonic!

    The GH4 will be a Beast... that's just my opinion. Love the GH3 images and Dynamic Range, and I've heard that the Dynamic Range will be much improve from what the GH3 is outputting. Even if it does not record 10bit 422 internally it's still nice, my combo will be GH4 coupled with the SAMURAI BLADE which = BeastMode. 96fps nice for those slowmos.. and lastly they said the image is not oversharpen meaning that it real natural and smooth, I love a softer but still sharp image. In my book it's a definite winner, but with all that said internal recording would of been nice as well.

  • karlkarl

    While still being a little bigger/heavier than I would prefer, the GH4 looks like my next camera. The specs look really promising. Let's hope the good first impression won't be contradicted by the first real-world recordings/experiences. I'm looking forward to see some actual raw pictures and raw sample videos.

    @rNeil: "... making it the first true 'world camera'... " - not really, I will still have to travel outside the EU to buy one that is not crippled to < 30min recordings. (Unless of course someone debugs the firmware... but that probably won't happen too fast ;-)

  • RRRRRRRR

    Did you see anything, straight from camera, original size?

  • jamesgh2jamesgh2

    Well looking at the stills I think I am doubtful this camera will be a good Hi ISO performer. Everything looks pretty muddy and artifact prone.

    The JPG engine in the stills seems to be either far from finished or just plain terrible. In order to see the real quality of the files we do need to see the RAW files.

    Its a shame because Miyatake's pictures are beautiful!

    And yesterday I bought a GH3! Classic timing.

    @rNeil

    I am one of those looking at the box under the camera and thinking ... cool uses, but ... why couldn't this be "ported" to exterior or cable-connected use?

    Not crazy at all, I was thinking the same thing over lunch. If you could fabricate a custom jacks w/ ribbon cables to fit those gold multipin jacks matching the box, I don't see why you couldn't place that box somewhere off-camera and just feed the signals with "jumper cables". Though you wouldn't have the screwbase holding them tightly in the camera's jacks.

    Maybe there's a crowdsource-funding possibility there... hm.

  • whynotwhynot

    It says that GH4 body is similar to GH3 and can take the same battery grip. Does anyone know about the screen size? I want to know if I can use my varavon loupe ex on the GH4? Or is the GH4 screen physically different in size (I know its higher resolution)?
    Anyone know?

  • azza_actazza_act

    Yeah, I think this camera with the blackmagic hyperdeck shuttle will be a great system for my needs... my BMCC and BMPC may go on sale in a couple of months :)

  • rNeilrNeil

    @3kids ...

    Again, just going from what was said in one of the 'official' links Vasiliy put on here, and I haven't done any guessing or extracting. Not much explanation from the Panny rep other than you could choose to shoot either PAL at 25/50fps or NTSC at the others making it the first true "world camera", whatever that is. Argue with that dude. :-)

    Can somebody enlighten me and explain why would anyone want to hack a 200mbps camera? Just asking.

    Because that bitrate is NOT available in 4k mode! The GH4 will be very good in HD with this specs, but in 4k mode there is only the 100mbps datarate.

    And by the way....you know: 100mbps is 12,5MB/s...and 4k in 4:2:0 would be 320MB/s....this means a compression ratio of 25:1. Maybe now you might understand that cranking up the bitrate on this camera isn't that wired of an idea.

  • thornthorn

    @Renovatio

    No 96 fps, crop of 2x+1.2x in 4k, up to 30 fps in 4k only, no native 422 10 bit colours (I did not understand how), and the price? Boh.. This camera is just an epic fail.

    If you don't think PCM sound, 422 10 bit, SDI, jamming timecode, 4K, higher bitrates, zebras, peaking, XLR jacks (with audio meters), and DC power, etc - if all that means "fail" to you, then you weren't ever in the target market to being with.

    Just keep waiting for someone to hack that 5200 to your liking, or the em-5, or the ep-5, or the 70D, or whatever other camera you own that isn't doing what you wish.

  • thornthorn

    Finding it slightly amusing that some are declaring that a camera that isn't even released for their purchase/testing needs to be hacked.

  • olli66olli66

    the price would be KILLER, thought it would cost much more anyway, someone has to send me a unit (don't want that nasty 30 min. limitation) so much talk about video specs...will pictures look better with this camera?

  • LongJohnSilverLongJohnSilver

    First preorders in Europe at 1500 euro... It seems true

    @rNeil "..that all cams would have the switch of recording format to be usable anywhere in the world" I don't understand the confusion, it will be switchable and a global camera, but European cameras will have the 30min restriction, simple..

  • rNeilrNeil

    Just going from what the person said ... and we'll all have to wait and see how it "plays", won't we? But the comment was quite specific ... that all cams would have the switch of recording format to be usable anywhere in the world. If so, well ... cool.

  • pizza4Dpizza4D

    @rNeil The NTSC/PAL and world cam options are about the framerates the camera offers (and about the video/HDMI output), not about the 29:59 minute limit. Even if the European model allows switching to NTSC, they will probably still limit continuous recording to 29:59 minutes, because otherwise the camera would have to be imported to Europe by Panasonic with higher tax. If the user can disable the limit, then it's effectively a camera able to record longer than 30 minutes and therefore falls into a different tax category. It seems very unlikely that switching a model made for the European market to NTSC will disable the 29:59 minute limit, unless the tax legislation specifically only applies to PAL framerates.

    I’m curious about the sensor dimensions. Looks like they are the same as the GH3’s (i.e. non–multi-aspect, or cropped, compared to the GH1/GH2). If true, it will be sad. I really enjoy the 18.8 × 10.6 mm scanning area of my GH1 and GH2 vs the 17.3 × 9.7 mm of the GH3 (and presumably the GH4).
