A Clear-Com Eclipse HX digital matrix system served as the all-IP wireless communications solution for Antenna Hungaria, the host broadcaster for the F1 Grand Prix in Hungary. The system was provided by HDwireless, the German wireless specialist, through AudioTechnica, Clear-Com’s distribution partner for Germany. The system needed to cover an extremely wide area including the pit 10 NOVEMBER ‘19
lane, the paddock and the TV compound, guaranteeing a reliable signal in a high-traffic audio environment, and providing exceptional audio clarity despite the extreme noise levels from the F1 cars. Previously HDwireless had used UHF radios for this event because of the size of the area they had to cover, but the team was keen to deploy its recently purchased Clear-Com solution. The system included an Eclipse HX-Delta matrix frame with 12 audio connections to the host broadcaster’s OB vehicle, plus V-Series Iris panels, FreeSpeak II digital wireless beltpacks and FreeSpeak II IP-connected transceivers. Patrick Nussbaum, Managing Director, HDwireless, said, “We
have supported the host broadcaster with wireless camera systems and a wireless video transmission for several years. Up to now we had used UHF radios as our intercom setup but we were looking for more flexibility, more channels per user and better audio quality. We had already used the Clear-Com FreeSpeak II digital wireless system for the 24h race at the Nürburgring in Germany and everything worked perfectly. In Hungary we set up the old UHF system as a back-up, but we did not need to use it at all. The Clear-Com system performed flawlessly and our customer was very happy.”

Beijing Television turns to IP-based EFP with Lawo and integrate Waves SoundGrid, additionally providing both MADI and IP RAVENNA/AES67 compatible interfaces.
In order to enrich its capabilities for dedicated audio production and broadcast of both sports and music – and especially for large-scale sports tournaments such as the forthcoming 2022 Winter Games in China (taking place in Beijing, Yanqin and Zhangjiakou) – Beijing Television (BTV) has turned to Lawo IP equipment for its Electronic Field Production (EFP) requirements. 18 NOVEMBER ‘19
For its first purely IP mobile EFP system, the broadcaster purchased a third-generation 32-fader mc²56 production console with 288 DSP channels as main desk, along with an mc²36 All-in-One console with 16 faders as backup, plus five A__mic8 and seven A__digital8 AoIP stageboxes from Lawo. The consoles provide 512x512 (mc²36) resp. 8196x8196 (mc²56) routing capacity with redundant router boards
BTV’s move to full EFP operation comes shortly after China Central Television (CCTV) took a further step towards an all-IP production environment with the recent installment of three IP-based Lawo mc² consoles. As with the CCTV project, the system integration was handled by Lawo’s partner NDT, who also designed the system using the typical spine-leaf IP switch network involving a couple of CISCO switches. The project began June 2018 and was successfully completed in July 2019.

BTV is no stranger to Lawo, as the television company has been using Lawo consoles since 2008 and very satisfied with the reliability and redundancy options of Lawo products, especially in a critical environment such as live broadcasts and sports productions, in addition to high-quality sound, and advanced and powerful RAVENNA/AES67
technology. In recent years, BTV has benefitted greatly through the use of a Lawo mc²66 digital console in its OB van – the first 3D OB Truck to be commissioned in China – which has been employed to broadcast major sports such as CBA (basketball club matches) and China Super League football matches. Consequently, the broadcaster has strong
confidence in Lawo, especially in the IP environment. This installation is the first IP audio mobile system within BTV, and the second for the whole country, using Lawo mc² series mixing based on full RAVENNA standards – establishing another excellent reference for Lawo IP systems in China.

DUBBING AND SUBTITLING
Leaders in dubbing and subtitling
The OTT revolution has opened the doors of the TV world to a large number of well-established companies in the movie industry. A good of example of this is IYUNO Media Group a company having experienced recent growth by merging with BTI Studios. The outcome of this partnership? The creation of a leading company in the dubbing, subtitling, accessibility and multimedia localization fields. TM Broadcast International had the opportunity to meet in Amsterdam with Chris Carey (Chief Revenue Officer and GM Americas), who unveiled to us the company's future and the latest technological innovations on which they are working.

DUBBING AND SUBTITLING
Chris Carey (Chief Revenue Officer and GM Americas)
BTI Studios has merged with IYUNO creating what probably is the biggest localization services company in the world. Could you provide more details of this deal? Of course! We announced that BTI studios and IYUNO have merged and our new company now is a global services provider in localization. The statistics are there: 1300 people, 82 languages and 40 facilities in 30 countries in the world… What we 38 NOVEMBER ‘19
see is that with the Internet distribution platforms, the distribution model of content has really changed dramatically. And publishers who own content and want to reach consumers no longer have to go through a local market pay TV operator: they can reach the consumers directly with these digital platforms. The internet streaming has taken away one of the barriers that content companies used to have, which was to convince pay TV operators to license their
content. And previously, the pay TV operator in many cases did the dubbing or the subtitling as part of their business model. Now the content company says: “I can reach consumers globally, I'll build a digital platform”. Netflix, Amazon Prime, Disney Plus… They're all coming and coming in spades. The very next critical factor is that you have to localize the content if you want to reach people outside your original product market. We see that the localization business is becoming a
really critical strategic decision for a company that produces content. They would say: “Great, I can reach people, I have a digital platform, I need a network, I need some video technology to do
the streaming applications to create the UI in the UX, I need localized content, I need subs and dubs…” That's where we come in and we will play a significant role.
We suppose that now that the Asian market is getting more and more permeable, localization services will be increasingly important. Yes, absolutely. In fact, we have facilities 39 NOVEMBER ‘19
DUBBING AND SUBTITLING
throughout Asia, where IYUNO has been building their facilities and capabilities. They were headquartered in Korea, Singapore... We have a footprint throughout Asia including mainland China, Hong Kong, Southeast Asia, Korea, Japan and everywhere. Our ability now is to really simplify the supply chain for our customers. The localization business has been pretty fragmented and our business strategy is to provide a consolidated service. You can come to us, IYUNO Media Group, and in one contract, tell us what markets you want to reach. We'll handle it, will do the subtitling, will manage the dubbing... We perform high quality dubbing and have excellent recording studios everywhere in the world. We've invested in the highest quality equipment, we have the best directors and we will find the right best actor for each role. We can provide a quick supply chain service to our publisher customers. 40 NOVEMBER â€˜19
BTI had its own platform called BTI Hive. Will this remain in this new partnership? Will you work with third-parties in this new stage of the company? We haven't finished all of the technology integration work yet. I would say that we have BTI Hive as a technology we have built and have been using. Actually, Itâ€™s built by a third-party service provider, Ooona, for us and then we made some customization.

DUBBING AND SUBTITLING
IYUNO has its own technology platform that they develop with their own engineering organizations. They've built something that is fully own, a source code development cloud-based service. We're looking at what's best in breed and we're going to take the best technologies from
42 OCTOBER â€˜19
each of these two and create a unified platform. The platform features workflow management, schedule management, project management, technical workflow, the network of subtitlers, the network of studios that are doing the dubbingâ€Ś And, of course, we're also aggressively moving to
bring machine-assisted translation into the subtitling world very quickly. We've been testing and evaluating all the different technologies that are out there and some are already running inside of our platform.
That was going to be our next question! If we had to name one of the
hottest trends in the industry, we would say that companies are bringing processes to the cloud with technologies such as big data, IA or machine learning. You said that you are already testing these kinds of procedures. What about security? That’s one of the main concerns of customers and platforms. Security is something that is near and dear to our hearts because indeed our content provider partners need to make sure that while we have their assets in our workflow, they are always protected. Piracy is
always a threat and we must ensure that secrets aren't leaked and content isn't compromised in any way. We have all of the industry network security protocols. Obviously, the encryption and security management that we do inside of our own houses is continually improving and security, as you know, it's not one and done. Security is forever: always monitor, improve, monitor, improve… That's part of it. There are thirdparty companies testing facilities out there like the TPN (Trusted Partner Network), that's run by the Mesa (Media & Entertainment Services Alliance) team. We
comply with all of the TPN requirements. We take the security part very seriously. How are we managing encrypted assets and what is the security protocol about what's in the cloud and what's in our own facility: that is part of our thought process.
People talk about the hybrid cloud as a future-proof alternative. Correct, hybrid cloud is one of the things that a lot of the companies in content security control are studying. So security, absolutely, big piece of the puzzle: micro services architectures, trusted 43 OCTOBER ‘19

networks, proper encryption and management of the network and the assets. And then back to quality, right now we do use machine assisted translation for subtitling in productions with some customers in Asia. It's more than just tested: it's actually being used. We only use it when our customers participate and, as you know, machine learning is only as good as the machine can learn. We have arrangements in which we provide customer data to train the engine and then it gets smarter and can do a better and more effective translation, but still today we don't have a unassisted solution that we think has the quality we want. We always put a human QC on the back end of the machine. Still today, I would say that the humans are doing more than just saying yes: he or she is fixing, adjusting, changing a few things if a word it's not gotten right... But that will improve over time. Subtitling will be 44 NOVEMBER â€˜19

dramatically improved by this process. It still needs a network of subtitlers and we still have a massive network of individuals that work with us. Their lives has changed because now, instead of spending a long time on one show, they can spend less time and do more shows. We can become more
efficient as an ecosystem by doing it at more costeffective levels. We're also looking at the other side, which is dubbing: How can we use technology to improve the dubbing workflow? Our platform schedules logistics, line counts, breaks down the actors that we need, organizes it so that the studio session
We was doubting whether to ask you this because maybe it might seem a bit like science fiction… Maybe it could work for smaller markets?
is very efficient… We use the technology platform to do that, the dubbing workflow. What about voice casting? Of course, we do voice testing and use streaming technologies, so that our customers can listen to tests on our secure platform and say: “Oh yeah that's the actor I want”. But the question
is… Can we do a voice print match? Can we look at sounds-like and run an algorithm that says which of my actors sound like this actor I'm trying to cast and maybe speed up the casting time? We will continue trying to evolve both. And someday machine voice performance will happen. Someday.
It is not science fiction. It will come. But in my business plan it's not yet dominant. Again: assist workflow, print matching… these things are the present. Actors acting with a director directing them and we recording it will be the predominant way during the next applications for some machine work that will be good enough for small markets. That would cover some other markets where the price is a big issue. Maybe a machine-generated dub would be a way to break in into the market at a lower cost without the cost of hiring actors and studios. It's coming!
In BTI you already had a large number of studios. I assume that that ammount has increased with the merger. Yes! That’s our big 45 NOVEMBER ‘19
DUBBING AND SUBTITLING
statistic now: 40 facilities, 30 countries. That’s quite impressive: most of those are dubbing, a couple of the facilities are management and subtitling.
Do you have technological partners for these facilities? We have a technology standard that we tend to use. Now two companies are coming together, so there are certain choices that may have made about which mic preamp do we use. The industry is 100% in Pro Tools, so there is no doubt regarding the recording platform. In mixing environments, we all have aligned very well around the audio formats, the Dolby formats, DTS support for home… Those are standards that I think everybody in the industry uses, including the two companies now together. But when it comes to microphone preamps and some of the other a-chain b-chain tech, there is some diversity and we'll align that now the two companies are together 46 NOVEMBER ‘19
and sort of making selections. I am an audio geek so I could talk to you about audio forever.
What’s IYUNO vision for the next three to five years? Do you plan to consolidate as the world leader in localization services?

The sports broadcast sector is no doubt one of the most buoyant fields in the industry. The sectorâ€™s strong commercial capabilities usually translate into large budgets enabling ambitious productions that are at the forefront of the technique in the world. For this reason, a large number of technical innovations are used in the field, such as the ones seen at the latest Berlin Marathon, an event that reached in 2019 its 45th edition. We discovered the latest innovations in this area through two interesting interviews: Peer Seitz, Head of Production, Infront Productions, the company in charge of producing the event; and Mark Grinyer, Senior Manager, Live Production Services, Sony Professional Solutions Europe.

Having a long-term partnership with the BMW BERLIN-MARATHON has allowed us to refine the production plan we implement every year. For

the 2019 edition we had more than 20 cameras covering the course, including fibre-connected and RF cameras, as well as cameras on a segway, motorbikes and one helicopter-mounted camera. In previous years, we started testing out the use of 4G-connected cameras for the marathon and this year weâ€™ve integrated a total of three 4G-connected devices to the live coverage. We also had a 4G back-up on our lead camera in case
of any issues with the RF coverage in general.
How many people have been involved in the production of the event? Approximately 150.
Which is the main technological novelty of this sporting event? This year we ran a test with two 5G-connected cameras, with footage shot from these devices included into the live coverage.
You have deployed Sony solutions. How has the collaboration been so far?
screen programmes and is a way to produce footage to engage with fans on online platforms.
It has given us the chance to try shooting with smartphones and see how the virtual production switcher can be used, and the way it behaves when paired with more traditional, linear broadcast workflows, for instance in terms of image quality. Certainly, it creates new possibilities for second
Was the production done in HD or 4K? The BMW BERLINMARATHON is produced in HD SDR.
Do you plan to include HDR technology in the future? For every production we are doing, together with our customers, we assess
the most fitting production format. For several projects, we have been utilising UHD in combination with HDR so far. In the future, we believe that even if the distribution channel will be primarily HD SDR, a production in HDR can benefit the overall user experience.
What has been the biggest challenge when producing this event? Probably set-up time. Itâ€™s a one-day event, plus

a test day the day before, and obviously we can’t start setting up a week before the race as we cannot disturb city life. Therefore, we have to be quick and use only two days before the test day to set-up. For such a big production in a rather public environment, the test day is crucial in order to have some time for trouble-shooting before the actual event.
You have a lot of experience in remote production workflows. Has that technology been applied to the Berlin Marathon? If not, will it be in the future? Remote production is a very exciting topic which opens up a lot of new possibilities. There are events where remote production makes a lot of sense and helps as well to free up budget in the long run for potential improvements or to invest in other/additional projects. As a host broadcaster especially, you always have to consider risk versus reward, though, as we 52 NOVEMBER ‘19
have an obligation towards all broadcasters taking the World Feed. We wouldn’t rule out that at some day the BMW BERLIN-MARATHON could be produced remotely but with a lot of variables for such a big event, and one taking place mainly in a public space, so far we’ve decided against it.
Interview with Mark Grinyer, Senior Manager, Live Production Services, Sony Professional Solutions Europe How important are sports productions when designing Sony solutions? For Sony, Sports is one of our key professional market segments. Both Sports & Live Events are proven drivers for technical and Production innovation. To ensure focus on Sports, Sony formed Sony Sports Innovations as a global
business unit on the 1st April 2017.
We heard at IBC that you will deploy a stateof-the-art technology at the Berlin Marathon. Could you give us more details? In Berlin, working with our partners, Sony not only deployed our latest products like the HDC5500 system camera and Virtual Production, but working with Sony mobile and Deutsche Telekom, we also used a number of prototype devices.

We would like to know more about the devices you used at the sporting event. Which camera system did you use? How many devices did you utilize? Across the event there were three use cases: Use Case #1: This was a trial of a fixed main broadcast camera (HDC5500) connected via a prototype low latency encoder and a smartphone. This camera was connected back to the main Production OB unit.
Use Case #2: Two roving cameras PXW-Z280 were directly connected to smartphones. Again, via the mobile network and a stream receiver (PWS110RXA), the streams were also available in the main Production OB unit. Use Case #3: Social content - a number of smartphones running XDCAM Pocket App were used to stream footage to the Virtual Production switcher operating in the cloud. The output of which was available for viewing as a web stream.

It has been a great team effort to synchronize all of the R&D and development effort to ensure we had viable production workflows with which we could trial real life use cases on one day.
What will be the future applications of this technology? In the end, how the technology is deployed is driven by production workflows. As the core mobile technologies transition from prototypes to ‘everyday’, we can envisage the ability to easily and quickly deploy cameras and cloud production resources which can only enhance creativity and so enjoyment for the viewers. 53 NOVEMBER ‘19
The winner of an EMMY Award for "Russian doll" embraces 8K recording and HDR
54 NOVEMBER â€˜19
Technical care is getting an increasingly important role in TV fiction. Long gone are those formats in which visual finish was a secondary issue to scripting. At present, maybe because of the appearance of players such as Netflix, Amazon Prime o HBO in the scene, direction of photography has evolved to become a decisive item for viewers. Chris Teague, winner of an Emmy award for Outstanding Cinematography for a Single-Camera Series thanks to his work in Russian Doll (Netflix) and also author of the staging of Glow, told the team of TM Broadcast International about his way of understanding TV technique.
55 NOVEMBER â€˜19
We would like to start by asking you to summarize your career in a few lines so our readers can get to know you better. I went to film school at Columbia’s School of The Arts in New York City, and before that I had studied photography and worked a bit as an assistant to a documentary DP. At film school I studied writing and directing, but I had some technical skills so I ended up being one of the go-to DPs for school exercises and short films. That work evolved into indie feature work, and in the past few years I’ve mostly been working in television.
56 NOVEMBER ‘19
If we had to identify a trend in the last decade TV shows, we would say that “cinematography evolved” compared to the 70s, 80s or even 90s. Do you agree? In your opinion, what is the biggest technological change that TV series has faced? Yes, the look of television has certainly become more cinematic and varied in past years. Part of that I believe is due to a wider variety of story material that lends itself to different visual approaches, and the advent of streamers like Netflix who are more willing to do unconventional things.
HD, 4K, 8K… Resolutions evolve day by day. You had to film “Russian Doll” with RED equipment working under those resolutions. How was the experience? How did you fell when filming with those resolutions? Before Russian Doll I had no idea why anyone would shoot higher than 4k if you have to deliver in 4k. After seeing the tests of the RED Helium sensor at 7k and 8k I saw how the oversampling of pixels can lead to a more rounded texture to the image, particularly when paired with appropriate lenses and color grading.
We have talked to many CTOs and cinematographers and they agree that HDR could work as a revolution, as color was decades ago. Therefore, they told us that cinematographers still need to learn how to use correctly this powerful tool. What do you think about this? How was your experience with HDR? I was hesitant about working in HDR, but it was actually a perfect format for this show. Once you spend a few hours in the DI suite working with the rich color and contrast of HDR
you tend to find the SDR image feeling a little flat and lifeless.
We would like to stop briefly at your work in Russian Doll. Could you describe the main equipment used for this production and why did you choose it? We shot on the RED Helium sensor. At the time I felt our only choices for Netflixâ€™s 4K mandate was RED or the Panasonic VariCam, and I had previously owned RED cameras and liked what I was able to do
with them. I thought the tests we shot with the Helium looked great and fit the show. For lenses we shot with the Leica Summiluxes. I have typically shot with older lenses because they are softer and more idiosyncratic, but I loved the Leicas for this because they look amazing wide open at T1.4 and despite being modern glass I still feel that they are not too crisp or sharp. 57 NOVEMBER â€˜19
A large part of the first season of the show was filmed in night environments. How do you face these conditions? I shot the entire show at 1600 ISO to introduce a little bit of noise and texture, and shooting at that ISO paired with T1.4 lenses meant we almost always had more exposure than we needed. The challenge was not getting enough light, but controlling the existing light on NYC streets to keep the show from feeling too bright.
In addition, you used different types of technological gadgets for some shoots, such as underwater or subjective scenes. What were the solutions you used? We used an underwater housing for the water work. Luckily our steadicam operator Kyle Wullschleger is an underwater operator, so he handled that very well. We also used a body mounted camera rig with a Sony A7SII, as well as 58 NOVEMBER ‘19
some shift/tilt lenses for the scene when Alan is drunk and walking on the roof.
Let’s move to the way you like to work. How do you face one particular project? What is your workflow? Each project is different. I try to get into conversation with every creative part of the team and let those conversations lead to concepts that will direct the look of the show. I like to test cameras and lenses to find the right feel for the show. Ideally I make a document of images and text to serve as a “style guide” that I share with my team to help get everyone on the same page.
Do you have a preferred manufacturer? Do you choose a different option for each project? We are very fortunate to be working in a time when there are many excellent camera formats to choose from. I think it is good to be familiar with all of them.
Is there any technology that you would like to be improved or implemented in the coming years? So much of our work in lighting is about balancing levels from interior to exterior, or shade to bright sun. I think the more our camera latitude increases, the less work we will do to simply balance things, and the more we can focus on being creative.
How important is postproduction in the decisions you make on the pre-production phase? I think my colorist is one of my key creative partners, and I like to involve them in the process as early as possible, as they help me make big picture creative decisions that will shape the look of the show. Nat Jencks has worked with me on many many projects and we share a similar visual sensibility, so he has been an excellent creative partner.
What is the biggest challenge you had to face as DoP? The biggest challenge is staying on top of all the different decisions that
need to be made in the incredibly fast pace of television. I never have enough time to devote the energy I would like to each and every creative
element of a project, so it is important to know what to focus the most time on, and still not let anything slip through the cracks. ď ľ

Real-time HDR to SDR conversion By: Varun Patel, Product Manager LYNX Technik and Lucien Lenzen with the Hochschule RheinMain University of Applied Sciences in Germany.
To address the increasing consumer demand for exceptional quality content, many media professionals are implementing HDR solutions into their workflows, utilizing image sensors and cameras that inherently support wider density and color ranges. HDR (High Dynamic Range) provides viewers with enhanced contrast and increased brightness and more vibrant color, resulting in a far superior image when compared to current standard HD and 4K UHD signals. Whether content from HDR cameras needs to be processed for delivery to HDR equipped displays, or whether HDR content needs to be converted to SDR to provide content to the vast installed base of 60 NOVEMBER â€˜19
standard SDR displays in a media facility, the demand for HDR is clearly there. One of the main difficulties involved in progressing from standard dynamic range (SDR) to high dynamic range (HDR) television is the need to provide good downward compatibility with the huge number of SDR television receivers already installed and in current use. The new generation of broadcast cameras can provide a much wider scene contrast range than conventional displays and it is obvious that converters are needed to handle the different formats. In cooperation with the University of Applied Science in Wiesbaden, Germany, LYNX Technik
AG developed a set of HDR to SDR conversion solutions for its greenMachineÂŽ platform which down convert high dynamic range (HDR) images to standard dynamic range (SDR) images. To understand the difference between a classic HDR down converter and the enhanced solutions that LYNX Technik has introduced, we should take a look at how contrast compression is performed. Many camera operators use a knee function to incorporate luminance information which would normally be outside the SDR range. Traditional HDR down converters work in more or less the same way. However, the capabilities of such
systems are very limited compared to the wide range of luminance information. Normally they use a fixed curve that doesn’t take much image content into account. Even if it does though, using a flat gradation to cope with a high contrast range will lead to a flat-looking image at some point. This is why the results of some more sophisticated approaches which use metadata to tweak the curve based on the image content are still not necessarily convincing.
Moreover, metadata is hard to handle in a live broadcasting environment. The problem of dealing with a higher contrast range at acquisition rather than at distribution may be a new one for the broadcast industry but it is an existing one for filmmakers and computer graphics artists. Film has always captured more information, so manual grading always has been and still is performed by a colorist. The problems with grading though are that it doesn’t work for
live broadcasting and it can be expensive. Meanwhile, computer graphics artists use various procedures based on tone mapping. These also have some drawbacks for live broadcasting: They can be computationally intensive for video applications and because they are basically designed for still images, problems arise from the temporal domain, leading to flicker artefacts. HDR Evie™, powered by LYNX Technik’s greenMachine® platform 61 NOVEMBER ‘19
was developed to enable live automatic contrast compression avoiding the artefacts inherent in classic tone mapping techniques. Statistical analysis is performed on every image to preserve as much scene contrast range as is necessary but at the same time as little as possible. For example, it is not expedient to set a very dark exposure to prevent some small irrelevant highlights from clipping while the main part of the image is underexposed. Based on models of the human visual system, especially around the perception and preferences relating to contrast, the algorithm calculates the amount of clipping, or rather contrast compression, required. HDR Evie is an automatic process which analyses the incoming HDR image on a frame by frame basis. Changes in luma will also affect the color impression. That is why the chroma is automatically adjusted to the new luma. Temporal filtering is performed to avoid flicker. 62 OCTOBER â€˜19
HDR Evie provides more than simply better image quality; it also affects the way in which content is produced. By optimizing the lighting balance and exposure, aperture setting becomes less crucial. As long as the information in the captured scene is not absolutely crushed or burnt out, HDR Evie will try to map it into the final contrast range. As a result, controlling aperture is much less critical on the production side. In a typical televised football game, for instance, some areas of the image may be
obscured by roof shadows while others are bathed in overly bright sunlight. The aperture needs to be constantly ridden but itâ€™s likely that the overall image will nevertheless be fairly poor. HDR Evie can enable both a constant f-stop number and a balanced image as long as there is no clipping at the camera output. Sensors that can deal with a higher dynamic range therefore work better. Of course, the f-stop still has to be adjusted if the lighting condition changes substantially; on a very good HDR camera sensor,
a single cloud would not affect the result, however an overcast sky would require a new setting. Production flexibility can be increased by reducing the need to light a scene. HDR does not provide a total solution; sometimes even making things worse. This is why there is also a need for HDR-toHDR conversion. This means not only changing the HDR signal type. For example: from Perceptual Quantizer (PQ) to HybridLog-Gamma (HLG) or vice versa, but rather balancing the image as in the SDR case. HDR at acquisition doesn’t always
work well on the intended HDR display. From evaluations with normal TV viewers, it can be shown that more local contrast and homogenization is also preferred for HDR signals. This is why HDR Evie can also be used to enhance HDR processes such as HLG. Because of the good downward compatibility of the HLG curve, the resulting (processed) HLG works very well on both SDR and HDR displays. Since HDR Evie is designed to work best with natural images, it can produce unintended changes (e.g. in exposure)
when processing synthetic images such as a color bar. Another limitation are the results from the temporal filtering. To avoid pumping, the adaption speed is restricted. On a crash zoom or very fast pan it is not possible to guarantee an ideal exposure all the time – but, on the other hand, a wrong f-number would be worse. Moreover, the image analysis needs one full frame before it can start its processing, leading to a delay of one video frame. HDR is still a challenging topic. Higher dynamic range at capture does not solve the problem of a nonhomogeneous lighting condition within a scene and can even create new problems. HDR Evie is designed to produce better images easily and economically, while optimizing lighting balance and exposure, and also correcting hue and saturation. 63 OCTOBER ‘19
