  • Now if only Blackmagic made an active m4/3 mount 4k camera...

  • Just noticed a headline that the Blackmagic 4K is now shipping and they lowered the price to $2995. Competition is a good thing. :)

  • I have a feeling waiting until NAB to make a purchase decision is the right move for many of us who already have a workable camera solution. That said, if Panasonic would have included a 10 bit 4:2:2 HD in camera recording mode, I would be ready to sell off my BMPCC. Coming from a 1" sensor format, I like the fact that there is a bit of a crop to the 4k mode as I will just crop a bit more in post and be able to use my collection of 1" c-mount lens at a higher than HD post crop resolution from the 4k video mode. Anyways, I don't care as much about the specs as I do about how it stands up against a RAW HD workflow when delivering HD resolution. We shall see...

  • For me, the best thing about the GH4 is that soon I will be able to buy a GH4.

  • The wedding photographer's video was a little disappointing in video mode when be uses the steadycam around the couple. The sky is blown out which doesn't show a lot of promise for dynamic range. I know it's too early to say but that's what I see. If dynamic range is more important wouldn't the Black Magic cameras still win? Everyone is talking about sampling and resolution, but I really want the GH4 to improve dynamic range. Will it be 11 stops even, or closer to 10 at lower iso?

  • 444 is nice over 420, but the limitation here is called 8bit. It worth get a recorder to have 10bit juice. 10bit 422 is waaaaay better than 8bit 444.

  • No sign of original files from that Yucatan vid eh? Either the grading or the white balance feels way off to me, so much so I can't even judge the camera (sooo blue at times).

    Also, I (only half joking) say my slider shots on my @driftwood/VK gh2 from two years ago with a crappy 14mm pancake still win. ;-)

    i think that the downscaling is going to be very popular on the GH4!

  • @Aria that's a +20 ...

    People have been complaining about specs that are still well above what we've got unless you wanna jump several thou is cash outlay. And besides ... not all "specs" are equal or even near equivalent. We'll have to wait until a final production version is out and run through the mill by a number of people to determine how much of a "jump" this camera represents.

    I'm thinking it will be a significant and very usable jump, but of course that's as much speculation as anyone here. Patience ... people ...

  • @bwhitz I'm no expert, but I think you're right that 4k 4:2:0 actually downscales to 1080p 4:4:4 which is cool and all, but I think it really demonstrates how silly it is to not have higher than 4:2:0 modes for 1080 in the cam.. This idea of yours sounds like a good idea to get quality 1080p 444, but you also get lower bitrate. Probably worth it in a few cases..?

    This.

    I too am tired of the bitching. I am soooo ready to preorder this camera.

    There seems to be some confusion about Timecode and the adapter. The adapter accepts Timecode from and external generator, usually a high-end audio recorder that outputs a stable clock that is then embedded in the video. And since the audio has the same Timecode, post sync is simple.

    Especially in a multi-camera situation.

  • @JohnTollwannabe in the old days I used to use timecode for the audio, but we did not edit in post, we just switched cams on the fly. So back then it certainly was handy. No drift, and right out the door. Maybe that was better! But now using more cams and doing much more work in post, I don't use it anymore. I'm not saying it isn't useful. I wouldn't turn it down if an easy format for it was available, because you get a precise lock for long events, but mainly I'm just syncing clips and audio as I go along. The other reason I don't use it is that I have cams at different distances so the have to be reclocked anyway, even if they are TC synced. You can use a superclock or a picosecond RME front end for the Tascam DR 680 and it won't drift, but of course your cam may drift. And drifting is annoying. Yup. But then you bump it along. If you clocked the 680, you could presumably daisy chain it (maybe a nightmare) to the GH4 TC in, but that's not what you are looking for I'm guessing. Maybe a neat solution will arrive in the aftermarket.

    I do think that the fact that there are dedicated pins for some of this stuff means you are going to see for example an aftermarket breakout box for the XLRs, or a breakout cable for SDI. I'm assuming the P48 (which probably is P36 but whatever) is powered by the brick, so no joy there. I'm hoping the SDI is just a straight pinout, so you can plug in a ten dollar cable. Hope. You may even see mini bricks with batteries and some features--some of those pins may be for unknown options or they may be assignable in software or firmware.

  • 10-bit 4:2:2 was what i was hoping for out of the box.

    Don't know if anyone has mentioned this yet, but wouldn't down-scaling the 4k and UHD modes to 2k give you a 4:2:2 8-bit image? So in a way, I guess it would have internal 4:2:2 recording if you're only doing 1080p projects...

    Or is 4k 4:2:0 actually equivalent to 2k 4:4:4 image?

  • Agreed, I think for me the most exciting bit of this camera is the 1080p modes.

  • I'm already tired of the bitching about this camera and it's not even a week yet. Seems to me that we've been given MUCH more than anticipated with the GH4. The brick has features in addition to what most expected and it's use is clearly not going to be for the majority of users. This is a specialty item and not just an XLR box.

    People are complaining about the 100mbps and 8bit internal 4K recording without really seeing much evidence yet of what it's gonna look like or be like to work with. There's a LOOONG way to go in terms of learning about this camera, it's strengths and weaknesses. I think people are putting too much into the 4K hype and not really looking at the camera as a whole. The camera is the core of a very powerful system that can be small and light or with the Brick built up to be more of a studio production unit. Those are totally different worlds and yet the camera can live in both at a reasonable level. That's really a nice set of options.

  • Voldemort says the brick is the only way to get 422 10 bit out of the camera in 4k .... he goes on to say you can get 422 10 bit out of it via the micro hdmi but its limited to 1080p

  • @stoneinapond

    your sir has the best all around answer from all the thread.

  • "...I think externally connected and recorded audio on a separate recorder/preamp is still the best solution for most people. Why invest a few grand in a huge brick that is limited to just that camera..."

    There seems to be some confusion about Timecode and the adapter. The adapter accepts Timecode from and external generator, usually a high-end audio recorder that outputs a stable clock that is then embedded in the video. And since the audio has the same Timecode, post sync is simple. So saying the "brick" is limited to just the camera is just stating the obvious (limited being the silly word). You wouldn't put it on an Olympus or other camera. And for those complaining about the size, go into a audio parts store and have a look at the size of a female XLR adapter. Then imagine two of them, four BNC connectors and a 4-pin XLR power adapter. I challenge anyone to make something smaller while still retaining functionality.

  • Does anybody know if the screen info still disappears after 10 seconds? I have been reading as much as I can and can't find anything about it - really hope it is now a menu option...

    As both EVF and screen are still OLED I have some doubts about any progress here.

  • A shameful post really. I bet he hasn't the camera. It's full of ads of things he get paid.

    He says.that the gh4 hasn't silent shooting...
