I want you to think of the Monitor Crawl like a Bar Crawl. You gather a few of your best friends, hit the road and keep drinking until you can't drink no more. Except instead of hitting the road we hit the Central Hall. And instead of drinking we looked
at reference displays.
Now—I've done this before, bouncing around looking at reference monitors. But always on my own. It's almost always boring as heck and you're never quite sure what to think about what you're seeing.
But bring a few very experienced professional colorist friends along?
This Monitor Crawl was not just my highlight of NAB 2015. But any NAB. EVER.
How did we not do this before? I have no idea. But it was spectacular and will be
repeated.
I mean, put a group of Colorists in a dark room looking at displays and the comments start flying! You're forced to really evaluate what you're looking at, form quick opinions and then have those opinions examined in real-time as you're all looking
at the same display with the same footage.
Our First Annual Monitor Crawl included the following colorists:
- Alexis Van Hurkman: Author and colorist (Minneapolis)
- Joe Owens: Prolific forum helper, technical book editor for Alexis and himself a first-class colorist—in all senses of first-class (Edmonton, Canada)
- Myself: Colorist and Tao Newsletter publisher (Orlando)
- Michael Sandness: I saved the best for last.
Michael is a prolific colorist with a really sharp mind. He works out of Splice in Minneapolis and Michael was the key to this Monitor Crawl.
He had done all the scout work early in the week. He knew where every dark room, housing every interesting must-see display was 'hidden'. Michael led us from booth to booth. We all examined and commented until we were bored and then he had us bee-lining to the next must-see booth.
Remember how I said this was the year I saw our future?
This 2-hour
Monitor Crawl is what I'm talking about... (and the following opinions are mine alone, the rest of the crew can speak for themselves)
The Monitor Crawl was filled with 'Gear I've never seen before, but will see again'
It featured two things: High Dynamic Range displays and... wait for it... Rec. 2020, of all things. Let's start with the HDR displays.
I've seen Dolby's initial forays into HDR displays in prior years. They were interesting but never really impressive to me. I always shrugged and moved on.
This year, the HDR displays were full-on crazy. For us, it started at the Canon booth
Canon showed a 4K LED
30-inch High Dynamic Range prototype. It has a peak brightness of 2,000 nits... perceptually, it seemed 2x-3x brighter than today's properly calibrated displays. And it (literally) felt like it.
Example: In the looping movie there's an interior tracking shot of a man
walking across a darkened bar. The sunlight shining in the windows glowed so realistically for a few moments it looked, well, real (in fact, several of us commented that the extreme dynamic range did almost as good a job catching the 'real' in 'real life' images as any 3D system ever has—and goes to show how important contrast is to perceived detail and depth).
But here's the kicker...
When the scene suddenly cut to a full-on exterior with a midday sun... my eyes hurt at
the sudden transition—they had to adjust just as they would in real life if I stepped out of that darkened bar at noon in the desert.
The Canon HDR was both astonishing and
concerning
I can't imagine color grading for days on end a film shot in the desert at high noon (as I did precisely, on an award-winning feature-length Indie just last year).
I have no doubt that HDR will be a serious health concern for professional colorists
Display manufacturers must address this issue. Eyes can't be replaced—but, not jokingly, colorists can be.
If we want to ensure long, healthy careers these 2000+ nit
displays must be designed to keep an accidental bump on a contrast ring from burning us out... literally. Or from the damage of sustained exposure to these super-high brightness levels.
That said... the Canon prototype was the most impactful of the HDR displays I saw during the Monitor Crawl.
The Sony BVM
OLED and HDR displays were both impressive
Yes. I think it's insane to buy a BVM at their $20K+ prices... but damn if you don't get image for your money. In fact, their BVM OLED is so good, the HDR monitor looked just like it—only packing more punch.
The Dolby booth was super-interesting—but for a different reason
They had a darkened grading suite set-up which featured a Dolby
Vision HDR display sitting directly next to a Dolby High Definition Rec 709 display. A colorist from Deluxe was driving an attached Baselight.
As he was grading the footage playing
through the Baselight, both displays updated simultaneously.
Of course, that set us upon a flurry of questions—which were answered very nicely, though they were surprised by the sudden onslaught of 4 gentleman asking some very pointed colorist-type questions.
Here is what we discovered:
- When color correcting to the Dolby HDR
display (rated at 4,000 nits but I don't think any of the images got nearly that bright... not in comparison to what we saw at Canon), they simultaneously color grade to a Rec 709 display set beside the HDR display.
- The 'downconverted' Rec 709 image is managed by a 'Dolby Vision box' attached to the Baselight (they said the box also talks to DaVinci Resolve). The image path goes from Baselight, out to the HDR display, in to the Dolby Vision box and then to the Rec 709 display.
- A 'Dolby Vision' grading layer in Baselight (or Resolve) gives the
colorist control over the 'Dolby Vision box' and how the HDR down-convert is managed. There's basic Lift / Gamma / Gain controls plus a few others for flattening the HDR image into the narrower tonal range of a non-HDR display.
- The 'Dolby Vision' grading layer then gets encoded as metadata with the final rendered output. When delivering the final master, the master is an HDR movie with metadata for normal range HD down covert. Any licensed Dolby Vision display can read the metadata and perform a real-time downconvert that the
colorist specified via that Dolby Vision grading layer.
- This means if you buy a Dolby Vision encoded movie today for your normal range HD display today. In five years when you buy your HDR display... that same movie will now play back in full HDR glory.
Cool stuff, right?
Of course, it took a few of us asking the same
questions over and over until we all finally 'grokked it' and left the poor Deluxe colorist alone. Unfortunately, the room was too dark for any of us to read name tags, so I can't give him proper thanks.
But it was this type of tag-teaming, and a quick huddle afterwards to confirm what we all thought we heard, that made this group Monitor Crawl
so exciting.
Wrapping up this Newsletter, here's where I saw something I didn't think I'd see for several more years
I saw Rec. 2020. For REAL. With my own eyes.
Now, to be clear, the Canon folks say their HDR prototype was showing Rec 2020. But with no before / after images, I don't think anyone on the Crawl thought
that claim didn't have three asterisks accompanying it.
But at the Christie booth, they demo'ed their RGB Laser projector on a gigantic screen. Their booth was open air but no overheads were turned on. Still, it was in the middle of the show floor, so hardly a proper
Black Box, yet the image was very bright (at half its potential brightness).
And the demo? It compared Rec 2020 to Rec 709 and DCI-P3 by freezing an image and cutting between the three color gamuts.
This was the first time in my life I actually saw the Rec. 2020 color gamut
If ever I'm bleeding Geek, right now is it and I'm happy to share!
In my recent podcast with FSI's Bram Desmet, he mentioned that only laser projectors can hit those super-saturated R, G, B primaries specified in the Rec. 2020 gamut. And you could see the difference. Especially the reds. You don't realize how orange'y our HD reds are until you see them cut into the Rec 2020 color space. Rich. Vibrant. Real reds. Real greens.
Plus... lasers! Now, I'm just waiting for my hover board.
On a side-note, I asked the Christie rep about the FDA certifications required for laser projector installations. He said they've worked out the specification... and as long as no one can look directly into the projector from closer than 13 feet, laser projector installations are considered safe to the public.
There it is. My report on the year I saw The Future at NAB
I could (but won't) go on. However, I do need to send a Special
Thanks...
Thank you Tao Treasurer—you're amazing! Not only would the hugely successful (and sold out) Colorist Mixer not have happened without her (we had 225 people this year) but she was a total trooper.
As we went to parties and networking events, she patiently found ways to keep herself entertained while I did the networking thing. She even managed to have a good time during the Monitor Crawl (even though she couldn't care less about it).
Next Week: We'll be back with a normal, linking issue of the Tao Colorist Newsletter!
