Masaru Suzuki, System Department Manager
SHIROGUMI INC. is one of the largest CG and VFX production studios in Japan. Their head office is in Aoyama, Tokyo, with two more studios in Sangenjaya and Chofu. This interview was conducted at the Chofu studio.
Could you tell us about your team organization and production environment?
Suzuki: We create VFX for films with two teams – the CG Team and compositing team. TWe prefer to have dual-monitors with an HP Z820 workstation. The main monitor is color managed for checking the final color, and the sub monitor is for operating software. Artists needs 10-bit preview so we chose NVIDIA Quadro GPU cards. The compositing team has been using the CG245W since 2011, while the CG team is now using the CG246. We’ve been replacing the monitors gradually, and with the film PARASYTE, both teams are using ColorEdge. We also switched from using ColorNavigator 6 to ColorNavigator NX for managing all ColorEdge monitors in the studio. For the PC environment, the CG team uses Autodesk Maya on Linux and secondary computers running Windows, both connected to ColorEdge monitors. The compositing team uses The Foundry NUKEX and Adobe on Windows 7 Professional 64bit.
Hayakawa: A total of 17 ColorEdge monitors run at the Chofu Studio. The staff consists of eight CG team artists and six compositing team artists. ColorEdge monitors are used by the director, two VFX supervisors, and as part of a shared workstation using The Foundry’s HIERO.
What made you decide to go with ColorEdge monitors?
Suzuki: A backlit LCD production monitor won’t look exactly the same as a cinema projector, but we feel the need to create an environment where the difference is as small as possible. The screening room at Picture Element, Inc., where our final color correction is done, uses ColorEdge monitors with extremely small color differences to manage data. PARASYTE will be finalized with the DCI-P3 standard so we determined it was necessary for the CG team to also have ColorEdge monitors for a linear workflow. Monitors that could accurately reproduce the DCI-P3 color gamut would also be essential for our CG team using Autodesk Maya.
Hayakawa: We began working with a linear workflow starting with our compositing team, which was using NUKEX. The CG Team had been working with sRGB monitors as their standard, making it unfeasible to switch the whole team at once, so they continued to use only the monitors they had until software support became available. Over the course of a number of projects, the compositing team was ready for a linear workflow and Autodesk Maya was also ready for the change. So with the timing for this production in mind, we switched our overall production workflow to this model. This meant that the compositing team would be able to see the images for PARASYTE produced and passed along by the CG team with a consistent look.
Suzuki: As far as introducing color management monitors to a company is concerned, I think you’ll find that no matter what company you look at, they need to be gradually phased in, and I think it’s best to do so starting from the last process in the workflow. We’ve found that the gradual phasing-in also works better because your artists will gain a stronger understanding on just why color management monitors are needed.
So one of the advantages of going with ColorEdge was being able to confirm correct colors, then?
How do you decide on the color settings for each project?
Suzuki: The director of photography and colorist handle this using the screening room at Picture Elements Inc.
Hayakawa: We receive and work with sequenced DPX images from post production.
Suzuki: In the past, we would have a single master CRT monitor that we would check with as we worked, and as we gained experience we would get a feel for the difference between the CRT screen and the theater screen to compensate for that, but we would still have to regularly check the footage on the theater screen and readjust it on the CRT until it finally matched. Nowadays, working on ColorEdge monitors lets every staff member check their work whenever they want to and be sure it’s the same as their collaborators. It doesn’t just improve work efficiency — it also improves our end results. I’m also really thankful that each collaborating company can be on the same page. At Picture Element, they also use ColorEdge for color checks in addition to their theater-like screen, so they provided the monitor setting data for the project, as well as allowing us to confirm the actual difference between their screen and ColorEdge. After making this confirmation, we applied this to every monitor at the Chofu Studio. At the time, we were making adjustments one computer at a time with ColorNavigator 6, rather than using ColorNavigator Network as we do today, so I divided the work up with Mr. Hayakawa and did the setup while the staff members weren’t working. …I really wish that we could have tried ColorNavigator Network a little sooner. It would have made it a breeze. [laughs]
Could you tell us about why you tried ColorNavigator Network from the start this time?
Suzuki: We already wanted to manage over a network. We have three studios within Tokyo, and when we consider gradually introducing ColorNavigator to other studios and doing the monitor adjustments one by one, it just seems unthinkable. We also liked the ability to check group-wide whether the set color mode is being used.
So after you tested it, you immediately switched every ColorEdge monitor to be managed with ColorNavigator Network, and were pleasantly surprised.
At Shirogumi, we strive to use the new versions of the CG software as well. If you don’t use the tools for actual work, you won’t really understand them, so we actively challenge ourselves to do so. Of course, we considered it while also making comparisons with the differences between it and ColorNavigator 6, which we had been using.
How has it felt to use ColorNavigator Network?
Hayakawa: Previously, we would try to find the time to visit each desk to input the settings, so we’re incredibly happy to be able to do automatic calibration now. Doing the settings and putting them into effect is such a piece of cake now. [laughs] It also helps to prevent calibration from being forgotten, the way that could happen when we would rely on people to do it.
Suzuki: Before we started using the ColorEdge CG series, we would have to take a color calibration tool around to each workstation and do the adjustments while they weren’t being used, sometimes changing the staff schedules to free up the workstations. It took a lot of time and effort.
The money spent on ColorEdge equipment has proven to be a great investment when you look at the time it’s helped us save on redoing work because of colors, time spent physically traveling to and from the screen room to confirm the color settings, and a variety of other invisible management costs. For administrators, there is a tendency to look only at the monetary cost of new equipment, but if you look at it from the perspective of using it for four years, the benefits really outweigh the cost.
ColorNavigator Network makes things easier not just in-house, but also for managing work with collaborating companies. Here in Japan, there are companies that don’t employ their own systems administrators, so if they can prepare even a single setup with the ColorEdge CG series, then we can handle the settings management ourselves while sharing them with our collaborators. Knowing that we can manage monitor details for our partner, from here, is a great source of relief.
For our most recent project, the film PARASYTE (released in theaters in Japan on November 29th, 2014), we shared our monitor details with our production partner company, DAG, using ColorNavigator Network as we continued through the production process. The management system allows me, the systems manager, to get a feel for every workstation at once. Then, for each studio, Mr. Hayakawa can see the details here at Chofu, and at Sangenjaya their systems department can do likewise. In the same way, the people at DAG can use ColorNavigator Network to see the details of their own managed workstations.
Could you share some details on working with DAG, using shared monitor information, on the film PARASYTE?
Suzuki: Before we even started, DAG brought a ColorEdge CG245W here and performed a calibration for us to make sure that the monitors were similar enough to each other. It was clear that they’re very attentive to monitor matters, and they were eager to set up ColorNavigator Network. Being able to do monitor management over a network made for obvious efficiency improvements. People at DAG also appreciated the fact that they were able to see monitor information like whether their calibration was successful or not at a glance, and that they can use the same project name for the settings as we are, to allow for shared use.
With this sort of mutual trust relationship, it’s best to build things gradually rather than to try to rush it all at once. I also like how you can switch between multiple settings, so I hope we can expand our activities into other fields, such as game production or things like signage, where the final target is an ordinary TV, as well as something targeting ad agencies, which handle a wide variety of images for the web, mobile applications, and TVs.For us as pros, it’s really the image that matters in the end, and so I think you have to optimize your display environment and your final quality management. You can use a master monitor to do your final check like in the past, but I really feel it’s important to make efforts to minimize any errors or discrepancies from the start of production.
Is there anything else about ColorNavigator Network that makes you glad to have it?
|Suzuki: I’d like to continue using asset data that I can register with ColorNavigator Network going forward. I can register the monitor users and usage locations, so it’s easy to manage where the monitor is being used. When it comes to system administration, I also find that the ability to see the monitor firmware and the connected PCs’ OSes at a glance has proven itself more and more useful in supporting users. Of course, ColorNavigator Network also has very user-friendly color mode settings, too. I also really like that the standard color spaces preset for video production includes not just DCI-P3, but things like Rec 709, sRGB, and other standards.|
Has it saved you time compared to before?
Suzuki: It has absolutely saved us lots of time. The ColorEdge CG246 and CG245W monitors allowed us to do the calibrations without needing to attach a sensor, and now (with ColorNavigator Network) we are working faster from the very beginning.
Hayakawa: I can still remember how setting up a new monitor from scratch would take a lot of time.
Suzuki: With ColorNavigator Network, I just have to load the pre-prepped settings files from the ColorNavigator NX management software, and from then on I can send settings all at once to monitors from ColorNavigator Network and start calibration, which has saved me a lot of time.
Is there anything you’d like to see in a future version of ColorNavigator Network?
Hayakawa: I’d like if the browser-based confirmation screen had a layout that would let me check with an iPad, too.
Suzuki: I’d love if there were a simpler version as an iPad app, just to let me do a daily check to make sure there haven’t been any errors or anything. Personally, I’d also like it if there were a UI that would let me see everything on a MacBook Air or Surface screen. I already have it set up to reduce the number of data columns displayed, but I’d like to see a little more work put into the UI design.
For asset management, I want to be able to use the asset management screen in ColorNavigator Network to designate a group, and then send settings to managed locations all at once. I think it would be really convenient for companies that have to manage a number of locations, and it would come in handy just for doing fine-tuning by location even just on the same floor.
Do you have any thoughts on using ColorNavigator Network in the future?
Suzuki: Well, as I was talking about earlier, the first thing that comes to mind is using it to collaborate with partner studios. For a lot of studios, just a single project would be rather small; I believe that lots of studios are working on two or three overlapping projects most of the time. I think ColorNavigator Network, which can uniformly manage multiple settings among these projects, can offer an effective solution. For us, if we add more monitors at our company that need to be managed, and if we can cut the length of time that setup and other work would take, then I think that would make for an overall reduction in wasted labor.
Hayakawa: For a number of years, we’ve been working with self-calibrating monitors. Previously, though, even if you did adjustments, as time went on you started to wonder if a monitor had perhaps drifted away from the target settings, and it was impossible to completely relieve these worries. The staff would use their experience to get a feel for any differences from the screen preview environment, but having to actually check the images in the screen room before making corrections was a real nuisance from both time and cost perspectives.
Having a system like ColorEdge where we can be certain that self-calibration is being done every week has been a huge source of relief. For the staff, knowing that what they’re working on is properly calibrated and matched has had psychological benefits too.
Suzuki: That’s true. For anyone who has a clear sense of what they’re doing, if they start by putting what they can do into practice, little by little, there’s nothing they can’t achieve. When we have a client who isn’t familiar with matters related to color, we have to find simpler ways to explain ourselves; ColorEdge is good not just for us using it, but for helping us do the important job of spreading knowledge and awareness of matters related to color.
Hayakawa: As our trusted master monitors approach the end of their lifespans, I think a lot of people have been worrying about where to set their targets. It is important to have a master environment that you can set as a target, but it is also important to manage quality during the production process by using ColorEdge monitors, and work in an environment that is as close as possible to your master environment. Having a management tool like ColorNavigator Network to support that environment has really reduced the burden on our staff.
