FS RAW upgrade for FS5 announced at NAB

Hi all again! Very exciting news these days…

Maybe you’ve just heard/read it in the typical NAB announcements or via social media ( https://youtu.be/WnitX19JZeo?t=2m50s ); the expected (and announced since the beginning) “FS RAW” upgrade for PXW-FS5 (“CBKZ-FS5RIF”) will be available soon. Very soon. So, let’s see what it means.

FS RAW? AND 4K? BUT… THAT’S A LOT OF BPS!

I’m sure some of you have heard, or, even better, have worked on NEX-FS700 and/or PXW-FS7. For you, this announcement will probably something “natural”, and nothing that I’ll explain here will be really new.

As you may know, through a 3G-SDI interface (the main output, together with HDMI, in FS5) the maximum picture format that can be transmitted is 1080/50p (or 60p). However, it a 4K resoution needs to be sent, we would need a minimum of 6G-SDI connector.

However, this announcement (as years/months ago with FS700 and FS7), means that a 4K RAW signal can be delivered through that BNC connector. So… how????

In NEX-FS700, a little piece of hardware upgraded needed to be installed. In PXW-FS7, a camera adaptor needs to be attached to the camera body, XDCA-FS7. This time, for PXW-FS5, we simply need a firmware upgrade that can be done by end-user (but not as “simple” as a regular FW upgrade).

But those three models share the same kind of communication: through that BNC connector. Instead of sending the video in baseband, such video signal is converted into data and then encoded (under Sony proprietary protocol) and sent in data stream into the receiver.

OK, IT’S DATA, BUT HOW TO DECODE?

The first solution that existed for recording RAW from a FS700 was AXS-R5. However, R5 was a recorder that was mainly designed to be fitted in the rear part of PMW-F5 or PMW-F55. It receives signal from a multipin connector.

So, an intermediate hardware is needed: HXR-IFR5. This interface has a triple function:

  • physical connection (it “emulates”) the rear part of a F5/F55
  • operation over R5: in F5/F55 operation is done via camera body. Here we’re missing such interface, so a set of buttons is needed.
  • decoding FS RAW signal: as said, that data stream encoded under Sony protocol needs to be converted into “video signal”, so that R5 receives it through its multipin interface.

This was the first way to record RAW from FS700, and it can be also used for FS7 and FS5. The only problem for some customers in this case could be the price: HXR-IFR5 + AXS-R5 + olivine battery + AXS memory + AXS memory reader can cost the same price (more or less) as the whole FS7.

FS5 RAW

So, some third-parties appeared; they held conversations with us, so that they could get access to the FS RAW protocol. Their typical workflow is to capture the FS RAW data stream and then convert it into a more “light” codec (despite it can also be RAW). They usually work over HDD or SSD drives, and use to provide also a monitoring solution. Obviously, the price is also smaller: about 1/4-1/3 of Sony’s solution. As you may have guessed, I was talking about Convergent Design with their Odyssey7Q/7Q+ recorder and also Atomos Shogun.

WHAT ELSE CAN BE ACHIEVED WITH FS5’s RAW UPGRADE?

Well, as you may expect from a camcorder that can reach up to 240 fps in Full HD, the FS RAW upgrade also improves the super slow-motion capabilities.

As you know, default super slomo feature in FS5 (and in FS7) works over a buffer. That’s why it is “cached”: about 8 seconds if shooting at 240 fps. Now, this “caché way” is only applied if we shoot 4K at 120 fps, in which we’ll have 4 seconds burst. That means that, if at 24p recording, we are shooting 120/24=5 times faster, which means that those 4 seconds are “time stretched” to 20 seconds. In 4K in RAW quality, not bad 😉

And regarding 240 fps, now there wouldn’t be time limitation if shooting in RAW; this means we can reach a “continuous” mode without caché.

 

According to my information, this upgrade will NOT be free of charge. Also, the procedure will be very similar to the one you should follow to convert your X70 into a 4K camcorder. Oh, and don’t forget you will need to update your FS5 into V2.00 (not available at the moment of publishing this entry) in order to be able to upgrade with CBKZ-FS5RIF.

 

Thanks for reading, and I really expect this little explanation is useful.

Regards!

HXR-NX100: announced at Broadcast Asia

Hi all!

Maybe some of you have been active this morning on social media, and have realized that we have just announced a new camcorder at Broadcast Asia event.

NX100_3q_02-1200

This new camcorder is named “HXR-NX100”. And it is undoubtfully a nice camcorder, but probably the main question out there is: “Another camcorder by Sony???”. And, yes, you are right if you are wondering that. But there are a few reasons to embrace this new announcement.

Firstly, let me remind you I am just “the technical guy”. Yes, I belong to marketing, and that could be seen as a handicap, but you can be sure I try to position myself much closer to the user than to the brand in most of the cases.

So, many of you may know about PXW-X70. A nice little camera, with a great (literally) sensor, and a top level codec (XAVC). It works really fine, and, due to its sensor resolution (20 Mp), I expected its low lights to be a bit “weak”, but when playing with it in dark environments, it is really, really solid when managing that kind of information. You can remotely operate it, so it turns it into the perfect camera for documentaries: with a couple of them in your backpack (no heavy weight), you can shoot a nice multi-camera production held by just one operator.

But, what about those cases in which such operator prefers to do an ENG job? Obviously, X70 is a light but powerful tool, but some users prefer, when operating a camera in a handheld way, to be capable to play with the classic 3 lens rings. Yes, you can do something similar on X70 (zoom on the hand grip, iris on the little knob on the front of the camera, and focus on the lens ring – when shooting with a 1″ sensor, bokeh effect is significant), but some users were telling us that using that sensor on a 3-rings lens would be a perfect combination not only for live events (ENG, interviews, sports, concerts) but also for fictional purposes in which DoF is a critical aesthetic tool. Even, we could drop some functions from X70, if we could work on such new model. If, for instance, you are a YouTuber, a student, a freelance, a wedding videographer… you will surely be interested on NX100, and you will miss nothing.

NX100_lens_05-1200

And there it is: HXR-NX100. Probably that was the gap we were missing during months: a high-level but basic price tool that suits almost every situation, in an entry and mid level.

[From now on, please consider that I haven’t had the model in my own hands, so I can just judge it according to the information I have, as well as my prior experiences with other models]

It will look very familiar for those of you that have already worked with any Sony model, but if you haven’t, you should know that operation in our camcorders uses to be very intuitive, and optimized for the operator (we bear in mind such a big quantity of feedback that sometimes it’s almost unmanageable 😛 ).

ABOUT THE TECHNICAL SPECS

Let’s talk a bit about the specs. Yes, the boring thing. But we cannot skip them.

¿Sensor? What has been labeled like “the grand one” or “the big one” (with no… let’s say… hidden implications 😉 ), referring to its size in inches. From my POV, it’s the perfect balance between those people for which a Super35 or an APS-C sensor (like on a FS100 or an EA50, respectively) is “too big”, since it demands a constant focus operation, and those ones that claim that a 1/3″ sensor doesn’t allow them to play enought with the DoF. So, what am I referring to? That either if you are needing a “reality” look (let’s say news or sports) or a more “aesthetic” or “fictional” look, you can reach both with this camcorder, via the way you prefer: closing iris, moving the camera a bit further, playing with the ND filters…

NX100_leftside_03-1200

… because, yes, it does have ND filters. So, good-bye to those situations in which you are shooting in a dark environment and, when going outside, you need to fastly close iris, increasing your DoF. Now, simply apply an ND filter, and keep your iris open. Nothing new, of course, but strange to be found in a camera ranged at this price.

But, Alvaro, if you have always recommended to use the same resolution in the sensor as we have in the outputs, why are you defending a 20 Mpx camera? Oh, nice to hear that question! Well, in fact, I keep saying the same: due to pixel size, I prefer the sensor resolution to be as maximum the same resolution as the highest output. Sorry? Yes, let me explain: if you are using a 4K-capable camera, I prefer sensor to be 4K/8.3Mpx, but no larger; that way, each pixel has its maximum area, so it can collect the maximum quantity of light possible. So, how could it be interesting to have a bigger resolution in the sensor? Obviously, we sacrifice pixel density (thus, dynamic range), but with the high sensor quality existing nowadays, that is affordable (unless we are thinking of latitude for cinema applications). On the other hand, we can use that bigger pixel density to analyze signal. And that analysis helps us to have other features available; in this case, the well-known Clear Image Zoom.

Yes, I have heard that before, but… how does it work? Actually, it’s really easy. In a classic Digital Zoom, the usual way to do it is through interpolation: if a value of “1” is found in a pixel, a value of “3” is in an adyacent pixel, and we want to “zoom in”, we simply use an average, so the result should be “2”. That could be called a “spatial interpolation” (similar concept to an intra-frame codec). But, according to not only the previous frames, but also a classifying algorhythm, that signal can be compared to hundreds of patters (let’s say not only “radial movement” or “panning”, but even some recognizable patters, like, let’s say, “face”, “sky”, “flowers”, “pavement”…), and then that prediction is processed together with the interpolating mechanism, so that the final result provides a significantly bigger quality when zooming in. Is it clearClear… Image Zoom. This algorhythm can convert the optical 12x zoom into a 24x, and, added to that, we can use a digital extender to reach a 48x zoom. You can take a look on a [low quality; sorry] video that I uploaded some months ago in my YouTube channel.

NX100_front_08-1200

Another feature that some users will appreciate is the codecs available in NX100. I will skip DV recording for obvious reasons. But, added to that AVCHD 2.0 that allowed up to 50p in Full HD (it is “only” 28 Mbps), this time we can use the same last generation codec we have, for instance, on Alpha A7s, which is an implementation of XAVC codec. Bear in mind that, for recording on that XAVC-S codec, you’ll need to use at least a “Class 10” or higher SDXC card. For AVCHD, Memory Stick (Pro Duo, Pro-HG Duo, XC-HG Duo) or SD/SDHC (classes 4, 6 or 10) can also be used. Oh, and, of course, stereo audio is recorded in LPCM (in AVCHD, it can be also AC3).

About the way to record, apart from the typical “relay” or “continuous” recording (one of the cards runs out of capacity, so the clip continues on the other card, since the camcorder has double media slot), or the “simultaneous” or “backup” mode (same clips on both cards; for example, for security, or for using one of them to start editing, and the other one for colour grading), there is a third way to record, that we saw for the first time in NX3 ( in this video ), which allows us to shoot DIFFERENT contents in both cards, with each card commanded by a different REC trigger. Imagine you are recording a live concert; in one of the cards, the whole concert can be stored, while in the other one, you can shoot just the highliths or each song independently. Very useful for editing, or for avoiding loosing some interesting take.

NX100_rightside_04-1200

I know this is getting boring (sorry for that, and for my poor English, btw), so I will just remind some other nice features, like the MI shoe (no external cables for UWP-D receiver or HVL-LBPC torch), the LowLux mode (highest sensitivity mode with an assignable button), picture profiles and up to 99 camera profiles (copy from 1 NX100 to another, or use the cam profile according to the actual situation), Intelligent Auto (optimal setting for a certain scene after evaluation), LanC remote control…

NX100_rear_06-1200

Mmmmmh… yes, but, what about SDI, WiFi…? Well, those are the features that, according to the price range, needed to be dropped from other models (for instance, X70). However, and this is also a personal opinion, in most of the situations in which this camcorder will be probably used, I woldn’t miss them (but, obviously, this is subjective).

NX100_top_07-1200

So, after that revision of the technical specs, let’s wait to have this nice little camcorder in our hands (I’ll probably have a pre-sales version in a couple of weeks) in order to see which sensations are provided. Unfortunately, I am not a skilled user, so let’s wait especially for the reputed guys to do some review…

Thanks for reading!
