Dolby Made Pictures
As IBC 2010 begins, there are a number of products that are going to be released, announced, and examined closely. One of which that I think will deserve all the recognition it is going to get is Dolby’s new color grading monitor. When I first started talking about this monitor about 6 months ago, people asked me “Why is Dolby making a monitor? I thought they were a sound company…” My answer to them was that if you look at it a bit more closely, you’ll realize that Dolby isn’t specifically a sound company, but rather an experience enhancing company. Some of the earliest Dolby products were all about improving the quality of a movie experience through noise reduction. This eventually led to Dolby Digital, Dolby Cinema Servers, Broadcast systems, a slew of consumer products, and now a color grading monitor. So while Dolby does have a large stake in the world of improving the fidelity of audio, their real mission is to improve the fidelity of the entire experience - now with a monitor to truly boast about.

I have had the privilege of working with some of the great team at Dolby and they have let us put the monitor through some real world testing. After some initial evaluations and careful calibration, colorist Ian Vertovec decided along with David Fincher (who was interested in the capabilities of the display as well) to do all the broadcast color trim mastering of The Social Network on the Dolby. After spending some long hours with the system, Ian is more than impressed with what it delivers and I’d like to share some of the highlights (pros and cons) of this new technology.
BIT DEPTH | TSN is shot entirely at a T1.3. Most of the film takes place indoors with practical lights spread amongst the deep-focused backgrounds. For many monitors, this ultimate shallow depth of field spells disaster for panels that cannot fully display 10bits per channel. Banding, quantization, solarization and random noise patterns are all artifacts of a low bit depth panel. The Dolby resolves greater than 10bits- so even when one feeds a base-band 10bit signal, the monitor can accept higher samples for a much higher quality result. This translates nicely into the deep, precise black/shadow components of the monitor. It is no joke nor exaggeration that we honestly asked each other (more than once) if the monitor was actually “on” when our Pablo was feeding black. Most impressively, Ian was able to move the lift on a picture less than 1/2 of an IRE and see a clear response on the monitor. On an LCD panel, it is not typical to experience response in values less than 1 IRE-especially below levels of 3. The Dolby borrows from both LED and LCD technology - enabling it to harness the strengths of both.WIth a film like The Social Network, the RED MX sensor delivered show detailing that I’ve literally never seen before-more than can be displayed on even the best DLP chips. The heart of this film lives between 5 and 15 IRE - making the shadows an important part of how the film looks and feels. The Dolby has really enabled Ian to have the precision of a CRT with the size and sharpness of a large plasma.

FILED OF VIEW | One of the biggest challenges of any LCD display is the limitation of consistency across a wide horizontal viewing plane. The Dolby is amazing when it comes to a strong horizontal FOV. In fact, one can clearly rely on a consistent response even when 90º off axis from the center of the monitor. Color imagery, contrast, and brightness all remain surprisingly equal. In most timing bays, the viewing arrangement is with a colorist in the center and a cone of view filtering out from the center of the display to the clients viewing the display either beside or behind the colorist. With a 90º viewing angle, clients up to 15 feet away can easily be 15 feet apart from each other without any visual variation to what the colorist sees in front. The limitation to the monitor is in the vertical viewing plane. The monitor only has about a 15º vertical plane-especially with brighter pictures. So the monitor must be level in the room and all people viewing the display must be within 15º of the center-but this is fairly typical for LCD screens, so while there is weakness in the vertical capabilities, the horizontal is the bigger challenge with viewing angles and the Dolby delivers.
MENU & CONTROL | The Menu system we have on the Dolby is not the final version. But even in this testing version the menus are easy to use, clear, concise, and the monitor comes with an external control pad that can be remoted right to the operator. I really like this idea because when have a post house, you will inevitably feed the monitor a multitude of signal types, multiple inputs and types of inputs, and color spaces. With the Dolby control surface, the operator can easily see the on-screen-display and know what they are looking at and quickly change a calibration, an input, or even a color space without having to go behind the monitor or navigate on-screen menus while a client is in the room.

P3 CAPABILITY | Perhaps one of the most interesting characteristics about the Dolby monitor is that it offers both Rec709 (full range and SMPTE) as well as P3 color space display. For a busy facility, this is a great option because you can easily grade a film in P3 on a DLP and then make trim passes, changes, or even fixes to the film in P3 without having to be in the theater. This also makes the P3 option great for QC’ing work and not having to book a large room or run a DLP lamp. While I’m not advocating you color correct P3 movies on the Dolby, it is something that is now on the table.
SIZE | The monitor is 42” diagonal (36” x 20”). While this is not bigger than some of the plasma screens that people are doing broadcast grading work on, it is larger than the largest of the CRT options for color correction. It’s much lighter and smaller than a CRT and though it has fans in the back to cool it (about 12” total depth) the monitor is fairly easy to move and place on even an average sized desk. Size is important when considering what to put in a grading bay and since most bays were originally designed for 32”-36” monitors, the Dolby 42” is a good fit.
RESOLUTION | The fact that the monitor is not a 2K monitor is a problem with me. The Dolby will only display up to 1920x1080. This really does become a problem-especially if you plan to work with P3 content on the display because P3 content is going to be 2048 or 1998 H. The monitor will accept a 2K signal, but will automatically perform a center extraction. One example that hurt us in the TSN broadcast pass was that we are working with a 2048 source file which is getting trimmed and pan-and-scanned to 1920. Because the monitor cannot display 2048, the east-to-west pan-and-scanning has to be done without the ability to view your over-sampled edges of the original aspect ratio. So when you pan-and-scan the only way to know you’re approaching the 1920 line is to go too far. In all honestly this is not a huge inefficiency but the fact is this Dolby display is clearly built for cinema and cinema is not a 1920 format and it is quickly moving further away from 1920 in the coming years (years in which I hope to still be using my Dolby monitor).
BRIGHTNESS & BURN-IN | The monitor has incredible brightness characteristics that give it the ability to be so bright it literally will hurt your eyes. With proper calibration this is (of course) not an issue, however the option of over-driving the brightness makes for some nice options with regard to matching grain, noise reduction, performing QC, and even compositing where brightness can help the artist make precise decisions. Because the monitor is using LED technology, I’m told the monitor cannot ever have burn in. Since we didn’t think it was wise to leave a zone plate on the display all night to find out, we decided not to test this one and take Dolby’s word for it. But I’m sure one of these days someone will forget to black the monitor and we’ll eventually find out if it is, in fact, true.
Overall, this monitor is no doubt better than a CRT. It’s smaller in size but has a bigger display, it’s lighter, easier to operate, faster to calibrate, needs less calibration maintenance, offers more I/O port compatibility, offers P3 viewing, supports LUTs, and better matches what consumers in general are seeing at home: large LCD and plasma screens. So if that is what consumers are watching, why spend the money on the Dolby in the first place? For me, the answer is that you will find better overall consistency in exhibition if you master to the highest quality instead of the lowest common denominator. The cost of this display is clearly pushing it towards a professional market: around $1,000 per inch. While Ian graded, we actually looped out of the Dolby directly into a Panasonic 50” series 11 plasma with SDI input board. This was a great way for us to see how images were going to behave once they ultimately reached the consumer. The Panasonic looks great! They have the same resolution and sharpness characteristics. They have the same brightness characteristics and both deliver a great picture, so again, why spend the money on the Dolby? The answer is simple: the further down the above list you go, the further apart Dolby goes from the rest of the fleet. And the ultimate result can be summed up in one valuable word: CONFIDENCE. Having technological confidence in a display devices gives confidence to the colorist. A confident colorist helps make a confident client. The CRT left big shoes to fill, and LCD and plasma screens never matched what the CRT delivered - even on a subjective level, to which many clients generally feel was the best “textured” image. From our experience, Dolby can clearly deliver superior images to CRT, and once again give confidence to our monitoring paths with a visible quality that has the name to match.
