The New Sony NXCAMs Have Uncompressed 4:4:4 60p HDMI Outputs*

Well, this is interesting. Sony's $14,000 F3 camera has all manner of professional HD-SDI outputs, including S-LOG with a $4,000 firmware upgrade. You'd therefore expect Sony's $5,000 FS100 to ship with a more limited set of outputs, and it does -- to an extent. While the FS100 only has a "consumer" HDMI output, there are some interesting things about this particular HDMI output. The same goes for the documentary-friendly HXR-NX70 and the twin-lens stereoscopic HXR-NX3D1 as well -- but don't get your hopes up, as that asterisk in the title comes with some disclaimers. What is it about these HDMI outputs that are unique?

First of all, the fact that the HDMI outputs are uncompressed comes as a surprise. They even offer 4:4:4 RGB output as an option (in addition to standard 4:2:2 YUV signals). This includes 1080p at 50p or 60p (depending on whether you have the PAL or NTSC version), and there is even timecode embedded in the HDMI signal. Here's the problem, though: there are no HDMI recorders out there that currently support these advanced features. Presumably one or more manufacturers of the multitudinous available field recorders will issue a firmware date in the future to be able to capture some of these non-standard features, but according to Allan Tépper of ProVideo Coalition as of now none of them can take in the 4:4:4 RGB signal at present.

That's not all, however. The reason for that asterisk in the post title? The output is only 8-bit. It's strange to imagine that an uncompressed output would be restricted in total colors, but the uncompressed HDMI signal is not available in 10-bit. I suppose this makes sense, as Sony would not want to give you an uncompressed 10-bit output from a camera that's 1/3 the price of their flagship model. Lots more details on the NXCAMs (including the tidbit that the NX3D1 is the only one of the three that will ship as a "WorldCam" -- meaning, it has both PAL and NTSC frame rates) at the the link below.

Here's a video about the FS100, in which Sony's Juan Martinez talks about the decision to apply a 2:3 pulldown to the 24p signal for the HDMI output:

Your Comment


again, while i admire that sony is doing this (and it is cool; well, kind of), i have no idea, unless you're really needing an available camera right now, why you would spend more money and get less features on this than to wait for a scarlet or an epic-s. seriously doesn't make any sense to me, and i'm a fairly open minded guy

Because while you're waiting for the scarlet and epic-s to come out there are people out there shooting on what is currently available and within their means. They're all tools, if there isn't a worthwhile story then it doesn't matter if you're shooting on 35mm film or an iphone, the story will still suck.

dude, did you not read what i said? I said, "unless you're really needing an available camera right now." Please don't make me sound like an idiot because you don't read my full post

He's right. If you had waited for a Scarlet when it was first announced, you'd be pretty screwed. RED does not deliver on time, and they don't deliver the hyped specs and unreal prices that are first claimed by their formidable PR machine.

As for the Epic...this is a high-end film-replacement tool, not remotely something competitive with a $5K camera.

I just can't quite get excited about the FS100. We're going to see some great stuff over the next few years.

June 17, 2011 at 5:24PM, Edited September 4, 7:54AM


I know the Scarlet & Epic-s will be great, but this cam (to me) is also a great step up from dslr shooting. I'm not going to spend all my time waiting for the "perfect camera" to come out. Red has been working on their camera for years now & I'm not absolutely sure if they will be able to keep up with demand when it finally hits the shelves. At the end of the day, on the day when I get ready to purchase my next cam, I'll be only be looking at what IS available to purchase at that present time. I'll consider others only if they have a definite release date. Right now, the fs100 is my 1rst choice.

How silly, manufactures spend millions in R&D with very talented engineers, just so the marketing department can cripple the camera just at the end, otherwise they get too good. get a life.

WHO oh who is gonna have the skills and motivation to hack the FS100 firmware in order to tap into the 444RGB possibility of this sensor? Or is this defacto limited by the circuitry in the cam?

ok wich the best camera for Digital film making, NXcam or PMW-F3?
i am confuseee... plss clear.....

June 26, 2011 at 7:39PM, Edited September 4, 7:54AM


Wow, 3D!
This camera blows the doors off the Panasonic AF100.
I have held both the Panasonic and the Sony. I do like the build quality of theirs allot more than the Sony.
But everything else about this camera is way cooler.
I can't wait for mine to arrive.

So many wankers on these site.... blowing off Red and the Scarlet. Honestly do you even shoot for a living? Have you ever shot with a Red camera? They overheat constantly. Phil Bloom sent his back. The FS 100 is an excellent camera for the money. Gearheads get a life. The F3 is a better camera for more money. This is about business and the tool you need to make living not about pretending to be a film maker and hanging out at Starbucks chatting about your next great indy flick.
