GH4 4K Panasonic video camera, official topic

    Me too, I have some info about the G4K: some people would be happy with the camera, but others would complain ;-)

    The "announced rumored specs" appear to be copied and/or extrapolated from the existing Panasonic cameras which appeared after the release of GH3.

    It's not hard to "predict": The camera image processor is Venus Engine IX, The Light Metering System is based on the 1,728-zone multi-pattern (G6, GX7,...), Focus peaking, Autofocus would be optimized to EV -4..18 (GX7), ...

  • RikerRiker

    More focus point's is the deal breaker. Especially for movie making :)

    On the more serious note, since this topic is called GH5 - does that mean that there won't be no "light version" successor to GH3?

    I thought I read somewhere that GH4K will be the premiere model and then GH5 will come soon after with weaker specs...yes, no?

  • endotoxicendotoxic

    yes i did , LOL :-)

    you are bulling me :(

    LOL

    You just copied it. :-)

    It will have a quad core processor.

    GH3 has one.

    Sensor reading is 50% faster then GH3 so much less rolling shutter.

    You only need some logic to guess it :-)

    maximum bitrate of 200Mbps ALI and 100Mbps IPB

    Same old shit.

    4K, you will have MOV + MP4 only.

    It can't be otherwise as Blu-ray standard for 4K does not exist.

    Focusing will be faster and have more AF points.

    What is exactly "more focus points"?

  • endotoxicendotoxic

    1) It will have a quad core processor.

    2) Sensor reading is 50% faster then GH3 so much less rolling shutter.

    3) maximum bitrate of 200Mbps ALI and 100Mbps IPB

    4) 4K, you will have MOV + MP4 only.

    5) In 1080p you will also have AVCHD.

    6) The camera will have focus peaking and the user will be able to change the color. Focus Peaking will also work from smartphone through wifi.

    7) Focusing will be faster and have more AF points.

    Agree, GH3 was very high in comparison to GH2. So if this weighs in at the same as the GH3, then that will be about the right price. Any higher and they're starting to take the piss a little :)

  • Vitaliy_KiselevVitaliy_Kiselev

    Right now the strangest info is price. I fear we will get a inhibited/restricted camera or price will be much higher.

    In fact, price is high. As from, pure cost view it will be almost same as GH3. :-)

    Plus Panasonic knows that NAB 2014 will be 4K NAB. Sony and all also compete for people who are ready to pay for entry products.

    I do not believe Pana reps went insane suddenly

    This is the cards that camera will be using - http://www.personal-view.com/talks/discussion/8688/sdhc-uhs-speed-class-3-cards-for-4k/p1

  • Vitaliy_KiselevVitaliy_Kiselev

    Thing here is that all Panasonic formats are mostly marketing terms made for their pro range. In reality GH4 can use a few, but it is not important at all.

  • itimjimitimjim

    AVC-Intra supports only up to 60p. Realistically on this camera, it's likely to be 24p, 25p and 30p. However, Panasonic have implemented off-speed recording on their Varicam range, achieving 120fps with AVC-100 4:2:2 10 bit. Again, I'd be dubious of what they'll ship in this product, so I'm expecting something along the lines of AVC-50 4:2:0 10 bit....as an absolute best case scenario. In all likelihood, we might be looking at 120fps Long GOP.

    Anyway, only a couple of days to see what is what :). Exciting times either way.

  • endotoxicendotoxic

    my guess is 12 stops of DR with improved video sensor.

    Well enough you can increase with this codecs maybe 2 stops more in post. 14 stops of perceptual DR is a good thing. And belive me, NMOS sensors are very organic. (call it minialexa)

  • Ralph_BRalph_B

    An earlier rumor said it could do 4K at 30P. That's the same number of pixels as 1080 at 120P. So, it does make sense.

  • sammysammy

    Love to know the Dynamic range specs .that's the most important thing for me .The 120 fps is major for me .

  • whynotwhynot

    The GH3 taught me to wait a little before I buy :-) Rumored specs may look good but until someone test drives it well I'm happy to wait. Then again perhaps that's just my bank balance speaking. :-)

  • jamesgh2jamesgh2

    If it has 1080p 120 at 4:2:2 it will be an instant hit. 720p 240 should be possible just based on the data handling powers.

    I really hope the specs aren't hyped up in the rumors because I already have my money saved. 120p 1080p sounds just so good! Too good maybe!

  • Vitaliy_KiselevVitaliy_Kiselev

    Guys, be less optimistic. As if Panasonic will read it all they will certainly think on dropping few features and rising price :-)

  • DrDaveDrDave

    I would buy one, so it isn't totally wasted.

  • Manu4VendettaManu4Vendetta

    Sorry if Im an ignorant, buy I have a question and I hope not be put the topic but has relation with this codec.

    That codec can compete or have a similar level to RAW? I've never tried video on RAW, but I shot photo still in RAW ever and the possibilities are almost endless, so I suppose if you record video in RAW also has tremendous potential. So I throw this question because I see the impact of the Black Magic can record RAW at low cost and the Magic Lantern on the Canon, I dont know if Panasonic is on the right way or wasted opportunity.

    Thanks.

  • disordinarydisordinary

    Exciting times.

  • azza_actazza_act

    Me too... the only thing holding me back is the DR.

  • bwhitzbwhitz

    Damn! I hope I can get a reasonable price for my GH3 and Blackmagic after this! Assuming the DR is around 11-12 stops on this thing...
