Panasonic 4k camera system info & updates

Audio could go out via the SDi to the offboard recorder.

Assumption.. the mother of all..

So with your logic, pany made a box with xlr input just so you can record audio externally via sdi and Not record audio on the onboard media. If this is true, panny just made the biggest piece of **** brick thats wayyy overpriced.

If you have need for the adapter you are most probably going to be shooting 10-bit video. I that instance, nothing gets recorded to the internal media.

Exactly. I held back from commenting out of fear of looking ignorant but it seems I'm not alone. I don't see why it could not at least record the audio. But I guess someone will post the PDF and spell it out for us.
 
In my head Ive 'assumed' that it gives you XLR for the camera, but I don't actually know..

The appeal to me of the camera is the modular use..

naked - Bcam/crashcam
Brick + internal = XLR in a 'dslr' (good for simple jobs)
Brick + external = better camera but annoyance of a recorder.. (good for higher level jobs)

Just applying some logic here. Attaching the adapter will turn off the internal microphones. My assumption (and that's all it is) is that if you are recording 8-bit video with the adapter attached that audio will then get routed along with the video to the internal card.
 
I assume it will work too (of course?) but then I would assume the R5 recorder on the F5 would accept a compressed codec for example (not true)

Lumix DMW-YAGH Interface Unit for GH4 from Panasonic is designed to give the Lumix DMC-GH4 camera the video, audio, and power connectivity required for professional video workflows. When attached to the GH4, the Interface Unit has 2 monaural XLR inputs for line or condenser microphones, and gives you independent volume control of the left and right channels. There is also an audio level display monitor and +48V of phantom power for each channel.

When it comes to video outputs, the Interface Unit provides four BNC connectors - two 3G-SDI capable and two HD-SDI capable. It outputs quad-link SDI 4K video in 4:2:2 10-bit, dual-link 4:2:2 10-bit 1080p up to 60 fps, or four simultaneous 1080p streams up to 30 fps - all with timecode. The Interface Unit also has a BNC connector for timecode input, and converts the GH4's micro HDMI output to a full-sized HDMI output. For power, a 4-pin XLR 12VDC input is available.

Please note: When using 4:2:2/10-bit output, simultaneous video recording to an SDHC/SDXC memory card in the DMC-GH4 is not possible.

Seems to present onboard audio from my reading of that
 
Amazing how nasty and rude people can get over a simple question, especially one that nobody can answer because the answers haven't been given to us yet.

My guess would be along the same line as Sam's. It would be unfathomable to me how the XLR inputs would not allow recording onboard. The YAGH is about CONNECTIVITY -- not specifically about external recording. It allows you to connect the camera in a professional environment, to monitors, to timecode, and to professional audio equipment.

I don't have a definitive answer, but I would say that I am 99.9999999999999999999999999999999999999999999999999999999999% certain that it will allow for onboard recording from the XLRs. Yes that onboard recording will be 8-bit 4:2:0, we know that, but I would 99.999999999999999999999999999999999999999999999999% guarantee that you would get onboard recording with XLR audio inputs.

Further, I think the assumption that the internal mic will be disabled is premature; Panasonic has made other adapters for other cameras (specifically thinking of the HMC40 here) and I don't recall the adapter disabling the onboard mic; on all the Panasonic pro cameras (that have built-in mics) you can choose whether you want internal or external recording, so I wouldn't rule out that possibility for this one (understanding, of course, that the consumer factory has never made a pro adapter box before, so it's ALL speculation at this point).
 
That was the best explanation of the cameras specs that I have seen so far. Now we (guys that do aerial video) just need an external recorder that can do Prores 4K 10 bit 4:2:2 via the HDMI port and doesn't weigh a ton.

Happy days ahead.

I can imagine some folks will have some black boxes at NAB with 4k recording from HDMI, and ten months later someone might actually have one working... Glad to hear you can get 4K 10 bit 4:2:2 through the HDMI port.
 
For the DR quotes, I would need those sources to tell me how much DR they have measured on other cameras.

I'm DR-obsessed, I have measured it on lots of cameras following different methods. I can quote myself saying that the 5D2-H.264 has 11+ stops of absolute DR (here), and also saying that it has around 6 stops of usable DR (here).

There are some weird things there. I can get A LOT of very usable DR on the 5dmarkIII RAW with ISO 3200. From your list you'd think the DR would be 4. Also the BMPCC is not 9.5 at ISO 1600 because you have to push the sensor afterwards up quite high to have any image at all because it would just be too dark otherwise. The 5dmarkIII RAW DR is wayyy better at high ISOs than the BMPCC. Of course you are measuring the 5dmarkII but there shouldn't be that much difference DR wise.
