Almost forgot……. FS100 Firmware Update.

One important bit of news from IBC. There will be a FREE firmware update for the FS100 to allow 30P etc on a 25P model and vice versa. So after the update, as far as I know, it will do 24P (23.98) 25P, 30P, 50i, 60i, 50P, 60P. Impressive! Now what I don’t know is whether the end user will be able to apply the update, or whether you’ll have to get it done by a dealer or Sony, in which case there may be a charge. I was not given a timeframe, but I would imagine it will be before the end f the year.

Arizona Lightning 3D footage.

Here’s a quick video of some of the 3D lightning footage I shot in Arizona last month. It was shot using one of my Genus Hurricane rigs in side by side mode and a pair of PMW-F3’s. The clip can viewed in 3D or 2D and the 3D mode selected by clicking through to Youtube. The night time and evening shots have been rotoscoped to enhance the 3D effect.

Help! I can’t get my footage into the edit suite.

OK, OK, it’s not me having the problem. This is something that cropped up on another forum. It’s a common tale these days. A cameraman that is trying to deliver a file based format to an edit suite that does not have software that recognises the native camera files.

Yes it frustrating and annoying. Trying to un-wrap or transcode can be time consuming. You might even have to, heaven forbid, buy some extra software.

So whose fault is this. Is it because the camera manufacturers are bring out new cameras on a yearly basis or is it something else? Should we blame the software writers, or maybe the computer manufacturers?

We all got spoilt by the use of DVCAM and DVCPRO which are variations of the consumer DV products, so the mass market consumer codecs and connections work for us pro’s too and these are built in to most NLE’s.

Since the advent of file based formats we expect to be able to instantly import footage with no extra hardware and free software, but with ever changing computer operating systems, continuously “upgraded” edit software and the desire for faster, bigger, better leading to new cameras arriving every year it’s hard for Sony, Panasonic etc to keep up. They will almost always be a step or two behind as they have to wait for the NLE software to be finished before they can write the free software to link the cameras to the editor.

But hang on a minute. Is this really the fault of the equipment makers or software writer? Or is it simply that we are expecting too much from a computer based edit suite?

The key thing missing from so many so called edit suites these day is SDi or HDSDi. Worst case scenario: Go back to basics. Output the video from the camera (or a deck) via SDI into the edit suite and record it on the suite. A HDSDi/Component/Composite cards cost very little and will allow the editor to ingest just about anything without any codec worries. Back in the day…. when tape was king…. It was expected that the edit suite would be more than just a computer, it would also have tape decks etc to allow you to get material in and out. I guess these day we just expect everything to work without investing in hardware.
One thing I’m guilty of, is always trying to have the latest software and latest cameras. In many respects that’s asking for trouble. No one forces me to buy the very latest, particularly software. It’s often better to stay at least one or two releases behind. let someone else sort out the bugs. Bugs that will inevitably only come to light in real world workflows when 1000’s of people are pushing the software to it’s limits day in day out.

So… Get an HDSDi card, stay on a stable release of your chosen NLE and make sure you have the hardware you need to play back your footage over HDSDi and you should be fine.

Before you shoot me down in flames… I do wish, want, desire that all cameras, all formats, all codecs will work without extra hardware in every NLE on every operating system at every resolution/frame rate etc with one simple push of the “import” button. But you have to be realistic with so many possible combinations, sometimes you have to bite the bullet and take a step back in time.

Travel Show shot with F3 wins outstanding Cinematography Emmy!

The Travel Channel show Anthony Bourdain: No Reservations – Haiti has won an Emmy for outstanding Cinematography. The award is shared by Zach Zamboni, Director of Photography and Todd Liebler,Director of Photography. According to my sources the show was shot using a Sony PMW-F3, so congratulations to them. If anyone finds a clip I’d love to see it. The F3 has to be one of my all time favourite cameras, I really enjoy shooting with it as it puts the creativity lost on small sensor cameras back into the hands of the operator.

Sony Professional Media Update.

Some good news to come from Sony at IBC regarding the supply of professional media, Sony SxS and Optical Disc for XDCam are now back on track and the Sony authorised distributors have good stock. For those of you who are also using DVCam media all lines in this format are now in a free stock situation. I’ve also been told that HDCam and HDCam SR are now in end to end production and although quantities are low at the moment there should be an increase coming into suppliers within the next few months.

My IBC Round-Up, better late than never!!

I spent most of my IBC on the Sony stand at what was unofficially known as the “ICE” bar, this had nothing to do with the famous Vodka serving Ice bar at the Red Square in Vegas (shame)! The ICE bar was manned by myself and other Sony Independent Certified Experts as well as Sony engineers and staff. We had most of the latest Alpha, NEX, NXCAM and XDCAM cameras but the best bit was that we also had a huge range of third party adapters, mounts, brackets and other widgets so that we could help and advise on different ways to get the most from your cameras. This was quite a departure for Sony as very often they will only show Sony products, but on the ICE bar we were able to talk freely about the myriad of different options that you have thanks to aftermarket updates and add ons.

The end result of this for me was an almost non stop queue of people eager to try different adapters, lenses or recorders on the fronts and backs of the F3 and FS100’s, so I got very little time to look around the vast show that IBC has become.

So what did catch my eye at IBC?

Sony 14x Servo Zoom for the PMW-F3

Starting on the Sony booth there was the new SCL-Z18x14 lens for the PMW-F3. This lens fits directly on to the FS mount and is not a PL mount lens. It is a 14x zoom giving a focal length range of 18 to 252mm, which for a Super 35mm camera is an incredible range. It is a servo zoom, operated by the F3’s zoom rocker and has auto iris, an optical image stabiliser and both full manual focus and autofocus via Sony’s familiar sliding focus ring system. The list price of around 9000 euros is very attractive, although you do need to consider that this is a T4 to T6.7 lens, so not very fast. However to put this into perspective an Angenieux Optimo 24-290 T2.8 will cost you in the region of 50,000 Euro’s and weighs a mighty 11kg (24lbs). One plus point for the Sony lens is that it does not breathe!

Of course instead of a PL mount or dedicated lens on the F3 you can always use a DSLR lens via an adapter. One of the stumbling blocks here has been that the iris on Canon lenses is controlled electronically by the camera, making them difficult to use on a non Canon body.

Mike Tappa shows off his electronic Canon lens adapter.

But not any more. Mike Tappa from MTF services has been working on this problem and we had one of his electronically controlled Canon adapters on the Sony booth. There are two parts to the system. A small electronic control box with internal batteries and the adapter itself. This means you can just get one control box and then buy the appropriate adapter ring to fit either a PMW-F3, the FS100 or Panasonic AF101. It’s not available just yet, Mike tells me it will be a couple of months with a target price of “less than 1000 euros”. I’m sure this will be a very popular product. The Birger adapter seems to have disappeared and it would seem that they are having issues getting it to work correctly, so Mike’s simple but highly effective approach is most welcome.

There were more and more booths showing camera rods, rails and camera mounts than ever this year so plenty to choose from there. We had a couple of nice Vocas rigs on the Sony booth that were sturdy and well made. Others worthy of a mention here are the new TLS Cineplates. Made for a variety of smaller cameras and including made to measure adapters for the F3 and FS100, these support brackets for 15mm rails are superbly designed and engineered and apart from anything else look fantastic. They are highly adjustable and the F3 version is designed to fit on the Arri 35mm bridge plate system that uses 19mm bars.

Genus Elite Matte Box

From Genus there is the recently introduced Elite Matte box designed for PL Mount and larger lenses. The Elite can take 4×4, 5×5 and 5.65×5.65 filters via innovative dual size filter holders. One way to support the Elite is a novel swing away adapter. This adapter is designed to work with Matte Boxes that are not already swing away. It mounts on the ends of a pair of 15mm rails and then the matte box support attaches to the adapter, the adapter itself can then be made to swing forwards with a clever double hinge allowing the matte box to swing forwards. This adapter can be fitted to a wide range of matte boxes, not just Genus ones. Of course you’ll need a 15mm rod system and genus have a new Uni-Plate universal base plate. This is really nice because as well as the usual front/back, up/down adjustments this also has a side to side adjustment with is useful for cameras with off centre mounting holes or off centre lens supports. Once you have your rails and rods in place then you’ll need something to mount all your accessories on and Genus now have both a 15mm and 19mm cheese plate kit.

Genus Cheese Plate

The cheese plate mounts horizontally and vertically and has holes for most of the common battery adapter plates as well as a multitude of 1/4″ and 3/8″ threaded holes. Of course before I move on from Genus, I have to mention my Hurricane 3d rig. At IBC we were showing the latest updates including a new oversize hood for large PL mount lenses and the Canon XF105 as well as the motorisation upgrade kit.

Motorised Genus Hurricane Rig

This kit comprises of a bracket and drive gear that allows you to motorise the Interaxial adjustment using standard follow focus motors. Attached to the rig we had a prototype “Today 3D” 3D control system with wireless dual focus and IA control. With this kit fitted the Hurricane Rig becomes a real delight to use and allows the Stereographer to control the rig from the video village allowing the DoP or operator to shoot uninterrupted. IA control is accurate to within 1mm. Not shown at the show was a 3D monitoring solution for non-sync cameras costing less than 1000 euros but more on that another time.

So we have cameras, adapters and rod etc, but what about lenses? Well for the PMW-F3 you could always get a set of Zeiss, Cooke or Arri PL mount lenses. We all know that these are good, solid lenses but what about Schneider lenses?

 

Canon Fit 75mm Cine Xenar II

Schneider are not new to this sector but they are now bringing in some very new lenses that were designed from the ground up to work with digital imagers as opposed to film. The Cine-Xenar II lenses are available with various mounts including Canon and PL mount. They are HD/2K/4K lenses with a telecentric optical design. The Telecentric design minimises breathing to the point where it’s barely noticeable (good for 3D) and ensures that the image projected on to the video sensor is flat, right out to the corners with virtually no vignetting. This means the image sharpness will be very even across the image giving a well focussed and even image. In addition the lenses typically have between 12 and 18 blade iris mechanisms for exceptionally beautiful Bokeh.

Baffles and Iris in a Cine Xenar

looking down into the lenses you can see the incredibly large amount of baffles used to reduce and control internal and external flare. One small quirk of these lenses is the way they focus. when you turn the focus ring the entire lens moves forwards and backwards, including the focus ring, so you will need a wide follow focus gear and a flexible donut or Nuns Knickers for you matte box. Although a little bit more expensive than some of the entry level PL mount lenses, Schneider claim that these lenses perform as well as some of the very best (and most expensive) lenses on the market so they may be an interesting option, I hope to get one or two to try out in the near future…  I’ll keep you posted!  One thing to consider is that purchasing a set of PL lenses is possibly a better long term purchase than a camera. Get a good set of lenses and they could last a life-time, almost certainly longer than most cameras. These lenses may be a great proposition as they are designed for flat, electronic sensors and they are good for 4k so they would even be a nice choice for the Sony F65.

Talking of the F65, I can’t not mention it here. The images from this camera still amaze me. They don’t necessarily look “sharp” but the level of small detail in the textures that you can see is incredible. Talking of incredible what about the price? 39,000 Euros for the body only or 75,000 Euro-ish for a full shooting kit is pretty good. Remember this is an 8K camera, recording 16bit RAW 4K.  Drool… drool…  just think of the flexibility you’ll have in post from that!

SR-R1 mounted behind a PMW-F3

Another price to take me by surprise was the price of the Sony SR-R1. Now I have always associated HDCAM SR products as being expensive. I’ve never even considered actually buying or owning my own HDCAM SR kit, the price has always been similar to that of unobtainium, £40k and upwards. But the SR-R1 is solid state, so there is no need for a super precise mechanical deck with spinning drums etc. This makes it a much cheaper product to produce and as a result the price is much, much lower. In fact it’s actually quite affordable (for a top end piece of kit) with a UK street price of less than £14,000. It supports Dual Link, 3G and 3D recording onto SR Memory using the HDCAM SR codec at between 220 and 880Mbps. If you are shooting a low budget movie or commercials a PMW-F3 and SR-R1 has to be food for thought.

Convergent Design Gemini

Of course for many, me included, £14k is still a lot to pay for a recorder, even if it is HDCAM SR. Now I have S-log on my F3’s I really need a decent 10 bit 4:4:4 recorder and the obvious fit is the Convergent Design Gemini. At IBC, Mike Schell of CD was proudly showing off working versions of the Gemini which is an ultra portable video recorder and monitor that can record single link 4:2:2 and both dual link and 3G 4:4:4 uncompressed video onto cost effective solid state hard drives as industry standard DPX files. Priced at around 4,900 Euros this is an amazing product considering it is both a recorder and HD monitor in a unit that fits into the palm of your hand and weighs very little. There will be future options for 3D and other uncompressed formats. Shipping is expected to commence in October, but not surprisingly there is a bit of a waiting list, so if you want one in a hurry you’d better get your name down soon.

While the Gemini does make a handy field monitor there is still a big need for small on camera monitors and viewfinders. Both Zacuto and Cineroid have had HDMI equipped electronic viewfinders on the market for some time. The early Cineroid units did have a few quality control issues and I have been assured that these have been addressed.

Cineroid HDSDi EVF on PMW-F3

As I needed an EVF for use on my F3 rig I decided to pick up one of the new HDSDi versions of the Cineroid EVF at IBC. This has a very solid metal body and a much improved battery system. The screen is the same 800 x 480  as the older model, more resolution would be nice, but it works and I find I can focus with it very accurately using the peaking function. One nice point is that the lag seems much reduced compared to EVF’s using HDMI and this make using the viewfinder much easier. With my eyes starting to get a little older I’m finding a decent EVF with a bit of diopter adjustment more and more necessary and I am pleased with my new purchase. The clipping guide that shows you when the highlights are over exposed is particularly useful and pixel to pixel mapping can also be used for critical focus. Overall this unit feels very solid and should withstand the bumps and knocks it’s sure to get.

PagLink battery system

So now I have even more kit to power what should I use? I have not tried these yet but Pag’s new PagLink system sounds very clever. Have you ever had to set your alarm clock to get up in the middle of the night to swap batteries over on your charger as you don’t have enough channels to charge all your batteries? I know I have and it’s a real pain. The new PagLink system allows you to stack multiple batteries together, not just to get higher capacity or more power for shooting, but also to charge multiple batteries from a single V-Lock charger channel. In addition you can put a pair of batteries on the camera and hot swap the rear battery for continuous shooting. Check it out, it sounds very clever indeed.

Talking of stacking devices together, how about Atomos’s new “connect” mini converters. These tiny (really tiny) HDMI to HDSDI and HDSDI to HDMI converters are designed to clip on to the rear of existing devices that use Sony F series batteries. The converters themselves are powered by F series batteries and cost just a little over £200 GBP. But the cleverness doesn’t stop there because each connect device contains an internal battery that can power the device it’s connected to. So, slap a connect on the back of a Ninja and you can run it for a couple of hours and feed it from either HDM or HDSDi. Put a battery on the back of the connect and you can hot swap batteries while recording. In addition you can store test charts in a memory within the connect and it also doubles up as a flash light!!!! While talking about Atomos they are just about to release the Samurai which is the HDSDi version of the Ninja recorder. It has a bigger and better screen than the Ninja so it’s the unit is a  little bigger. Priced at 1145 Euros this really is a bargain for a 10 bit HDSDi recorder.

A few smaller notes.. The Sound Devices PIX240 will record 10 bit ProRes and DNxHD but it’s big and heavy. Nicely made but quite a weight to bolt on a camera and there is a big fan in the back of it. The KiPro Mini will get an upgrade to allow DNxHD recording in the coming months and Sony won an IABM award for their OLED monitor range. You really need to see OLED monitors in action to appreciate just how good they are.

So.. I’ve got a ton of work to do so can’t write any more now. It was great to meet so many of my readers at IBC.. Hello to all of you. I’m going to re-visit EX1 and EX3 picture profiles in the coming months as well as a whole series of S-Log tutorials. Catch up again soon.

 

Exposing when shooting S-Log.

The question over whether to deliberately underexpose or not with S-Log came up recently. I believe that you need to evaluate the entire scene when shooting S-Log and that the often heard “underexpose by a stop” methodology may have some issues. Here’s my take on the situation:

A couple of caveat’s first: Most of my F3 S-Log work has been in indoor situations as I have been tied to recording to various less than portable 10 bit recording solutions, so very often using a restricted contrast range. I’ve only owned S-Log for my F3’s for a short while now, so many of my earlier tests were on 3rd party cameras, some of these were beta cameras.

I have not fully tied down my workflow. I’m still investigating external recorders, everything from the Ninja, Ki-Pro, Sound Devices and of course Gemini. I’m leaning very heavily towards the Gemini as I do a lot of 3D and the Gemini LCD makes for a fantastic monitor.
Back to exposure, this is obviously going to be a slightly contentious area as there is no real “correct way to do it”. While I might not agree with pinning skin tones or anything else for that matter to one particular brightness range, that does not mean I’m right and anyone else is wrong, it is just a different approach and methodology. At the end of the day, if it works for you and gets the results you want, then that will be the way you should go, these things are not black and white, right or wrong.
A very un-scientific test that a did a while back was an eye opener for me. I was exploring the finite latitude of S-Log compared to the F3’s cinegammas. I did a couple of very quick shots, you will find them here: http://www.xdcam-user.com/2011/06/pmw-f3-s-log-and-cinegamma-quick-look/
When I filmed these two examples I was looking at dynamic range, I exposed in both cases with the bright whites of the back wall behind the girl just going into clipping so I could then see how far into the shadows I could still see useable detail. I was not concerned about getting the skin tone exposure correct. When you look at the raw S-Log it really looks pretty shocking and even I wasn’t sure how much I would recover from the highlights and the girl is a good stop overexposed. However after a very simple grade using only the colour corrector in FCP, I was able to extract a pretty good looking image and it’s amazing how much detail was actually retained in what looked like over exposed high lights.  The Girl’s skin tones which I’ve measured at over 85IRE came down very nicely without any issue. A proper grade in a grading suite would I’m sure improve them still further.
What this very crude test told me was that you have incredible flexibility over where you put skin tones, you can comfortably move them up and down in post by a quite significant margin. Also seemingly overexposed S-Log highlights will contain surprisingly large amounts of fully recoverable detail. In the same test I graded the Cinegamma material to try to recover the shadow detail that was lost by due to the reduced latitude. This involved attempting to pull up the shadow areas. While this was somewhat successful, what became very apparent was the way the noise increased quite dramatically, this is something I have been aware of since I started using Cinegammas many years ago, pulling levels up will increase noise.
So… when I expose with Cinegammas (as I have done for many years) I have always been very conscious of the noticeable effect on noise that trying to lift underexposed parts of the image has. Very often in the grade the limiting factor as to how far you can push the image has been down to the noise floor and noise effects. This has mainly been with Sony EX’s which have a 54db noise floor.
Now with the F3 with have a dilemma! S-Log gives us another +1.5ish stops of dynamic range, but at the expense of a +6db increase in noise due to the +1 stop increase in sensitivity associated with S-Log.
Lets say for example that we shoot a shot with a person and we under expose the face by one stop (one stop = 6db).
If we do this with with the Cinegammas and then grade the shot bringing the face up one stop then the noise will increase by 6db from the base noise figure of 63db giving a final noise figure of approx 57db (in the case of signal to noise, a lower number is worse).
If we do this with S-Log and then grade the shot bringing up the face by one stop then the noise will increase by 6db from the base of 57db giving a final noise figure of approx 51db.
So the S-Log image becomes twice as noisy as the cinegamma material and therefore depending on the footage, it is quite possible that you would actually be able to push mid ranges and shadows further with Cinegammas than S-log in an underexposed situation due to noise issues. The S-Log and Cinegamma curves are almost identical up to over 50IRE, so latitude performance under 50IRE is essentially the same. See the charts on this page: http://www.xdcam-user.com/2011/05/s-log-a-further-in-depth-look/
If I get some time at IBC I might see if I can set up some tests to show this in practice.
Now given that I have seen for myself how with S-Log skin tones can be pushed down just as much as up in post, I tend to try to evaluate the entire scene and consider how it will be treated in post before choosing how to expose. In particular I don’t want to expose so that the entire scene will end up being lifted by a significant amount, as noise will become a concern. This isn’t always going to be possible as there are many shots where highlights have to be protected, but I don’t believe that you have to set skins etc at any particular narrow brightness range, I tend to let skin ride somewhere between 45IRE and 70IRE depending on the overall scene.
If I can fit the contrast range of the scene into the 11.5 stops of a cinegamma then I will often use the cinegammas over S-Log because of the noise improvement. S-Log comes into it’s own where you have an extreme contrast range that needs to be captured. However at the end of the day you do still have to remember that the end display device is unlikely to be able to display more than 7 stops with any accuracy!
One tool I have found very useful is the BlackMagic HDLink box. I often use this to connect to a monitor as it has the ability to apply LUT’s very quickly. If you have a PC connected to the HDLink you can go in an modify the LUT curve in real time and in effect do an on-set grade. The HDLink is only $499 USD.

IBC starts Friday…. what a big show it’s become!

Hi all. I’m still here, just been busy off in Arizona shooting storms in 3D and then a quick family holiday before my wife and daughter forget who I am!!

Anyway is business as usual again and I promise some really interesting video tutorials are in the pipelines on 3D, S-Log, Gamma Curves and the Colour Matrix, so do keep checking back.

Anyway, jut 4 days to go until IBC and what a big event it has become since it first started in 1967. I will be helping out on the Sony Booth on the “ICE Bar”. It’s going to be a bit like an Apple Store Genius Bar, only manned by video professionals and Sony ICE’s (Independent Certified Experts). So please drop by and ask all those nagging questions or come for a chat about picture profiles or anything else you want to know more about. I’ve been told there will be lots of F3’s on the booth wearing all kinds of 3rd party fashion accessories plus of course the FS100 and F65, so plenty of gear porn.

Talking of IBC, Quantel and  have been busy preparing all kinds of stats about the show and they do make interesting reading, last year over 48,000 people attended the show compared to the 1,300 of the first year. You’ll find a page of info here: http://blog.quantel.eu/2011/09/infographics-ibc/
