    @Vitaliy_Kiselev

    Apparently these 3rd party batteries are identical to the original batteries and they are supposed to work in the GH3 and GH4. I have a set being delivered this weekend.

    @jamesgh2 Did you notice in the comments that the video was shot with firmware v1.0? I think we should start seeing some reviews pretty soon now that firmware is final.

  • lenuisiblelenuisible

    @driftwood - Hi Nick, were you able to test Wifi (live view when recording, HDMI output when remotely controlled) ?

    Txs in advance !

  • jamesgh2jamesgh2

    Love the detail this camera can produce, even in less than ideal conditions. Cinelike D is probably going to be my default profile.

    could I buy a battery in germany though my gh4 will be the US model...

    For now batteries do not care where you buy them, but they need to be original ones :-)

  • TronTron

    Looks like Amazon is listing April 30th as the official release date for GH4.

  • kevin_kirchmankevin_kirchman

    @olli66 yes, it is the same battery as the GH3. I don't know about the EU batteries on a US body.

  • olli66olli66

    anyone knows if the battery will be a new model or can I use the ones from my gh3? could I buy a battery in germany though my gh4 will be the US model...

    Very interesting! Some description about what is each file? (recording mode, lens, other settings)

    I agree on the 96 fps, the footage I've seen thus far appears to look more like upconverted 720P. Not necessarily bad, but not as solid as 1080P mode either.

  • arumarum

    @driftwood, does the 1080p mode have the same crop (x2.3 was it?) as the 4K, or does internal 1080p use more sensor and have a "standard m43" x2 crop?

  • sammysammy

    @driftwood , I heard from a couple people that the 96fps is not all that in terms of image (1080p) compared to 60p (1080p) , is that correct? how would you compare it to the quality of 1080p (from internal 4k 24p), thanks

  • driftwooddriftwood

    We're doing a load of tests over the next three days here at Driftwood Productions.

    Someone asked a EX Tele question a few pages back: Answer: Ex Tele only goes to 60fps in Variable Frame Rate.

    @AdamT You can't record to card in 10-bit mode remember - only 8 bit 4:2:0.

    You can record in-camera 8-bit 4:2:0 and select an output of 422 8-bit thru hdmi and record externally at the same time. 10-bit 422 mode output/record is thru HDMI only.

    I'll be testing the YAGH's passthru too.

    Record the 3x over HDMI !

    @driftwood - better 1080p feeding the ninja 10 bit downconvert from 4k, or setting the GH4 to say 200mbps 1080p and 10 bit output? Sorry if you haven't got round to comparing these..

  • mrbillmrbill

    so clean feed with on screen display info off - thanks!

  • driftwooddriftwood

    As I said earlier its 4K down convert in-camera NOT the Ninja doing it.

    @mrbill Nope. See images 'INFO DISPLAY = Off'

    @driftwood - does this mean you have to have the LCD screen turned off when downscaling from 4k to 10 bit 422 1080 thru the hdmi out? Thanks very much.

  • AdamTAdamT

    @Aria I believe the GH4 downscales 4K to 1080 before passing it through the HDMI out port. As far as the Ninja knows it's just getting an ordinary 1080 signal.

    But as someone pointed out at the place who's name shall not be spoken, the key question is how the camera is doing the downsampling. Is it actual downsampling as the A7S seems to do in camera, or is it pixel binning or line skipping. If it's not actual downsampling then there's probably no reason to record 4K internally.

    The other question is, is it actually putting out 10 bit data, or since the 4K is recording 8 bit to the card, is it simply putting out 8 bits of data in a 10 bit container?

  • AriaAria

    @driftwood, To be honest i'm shocked that the Ninja 1 can take the 4k and downscale on the fly to 1080. That's kind of amazing to me. I don't understand how it's doing it, but hey if it can do it, who cares? I hope you can post some images from the Ninja footage to show what it looks like. This sound promising for those who just want great 1080.

  • Ian_TIan_T

    @driftwood, not sure if you could do this but a good test would be for one to shoot using the Ninja out of the GH-4 to get 4:2:2 10 bit 1080p vs recording 4:2:2 10bit 4K and down-converting in post with an NLE. If the image looks exactly the same then using the Ninja would be the best way (on the cheap) to finish in Full HD. Then again you'd need one of those new expensive 4k recorders to actually do the tests.
