Magic Bullet Mojo has been out for a few months now, and you guys seem to be figuring it out fine on your own, but I thought I’d record this guided tour anyway, because when I put the headset mic on I feel just like Janet Jackson.
Magic Bullet Mojo is $99 on its own, or available as a part of the Magic Bullet Suite.
In many of my writings about color correction, both here on ProLost and in The Guide, I’ve talked about the balance between an aggressive “look” that helps tell your story through the use of a pervasive palette, tone, style, and feel; and the preservation of appealing skin tones. When grading a scene, you can push your look much further if you don’t lose track of appealing skin tones. Or, if you so desire, you can make a strong visual statement by choosing to allow your skin tones to get subsumed by your look.
The truth is, skin tones are just one of a small handful of what I call “memory colors.” Memory colors are colors that are, in the minds of your audience, inseparable from certain common objects or events. For example, the sky is so associated with blue that you might feel that you see those two words together as often as you see them individually. The same goes for green and grass.
The most basic idea of color correcting is that you are making colors correct, which is to say that you are making objects on the screen appear to be the colors that we know them to be.
The funny thing about this seemingly simple task is that it can be quite difficult. And it’s difficult for exactly the reason that it’s important.
The human brain is so tied in to our eyesight that we internally auto-correct for certain colors. This is the very definition of a memory color. For example, if you grew up in the United States, you know that a stop sign is red—so you tend to see an image of one as being red even if the color is way out of whack. In the shot below, we recognize the bald head as that of a Caucasian male, even though the white balance is incorrect.
We see his head as skin-colored, even though empirically it is actually almost perfectly gray! You might not believe me, so here’s a crop of the back of his neck to prove it:
This a variation of a common optical illusion called the Same Color Illusion. We “know” that square A and B are different shades of gray “in real life,” and that knowledge prevents us from seeing that they are in fact the exact same shade in the image (click the image to see proof).
Back to the head. Even though they “know” what color it is, your audience will respond more favorably to a memory color object if their knowledge of it matches their experience, rather than fights it. And so it falls to the colorist to correct the color of the head, to make it head-colored rather than gray.
In 2008 I pointed out an example of this from the trailer for The Incredible Hulk (Steve Bowen, colorist). Edward Norton’s face appears the same color whether in a cool scene or a warm scene.
Preserving skin tones is important, but so is preserving other memory colors. Here’s a shot from Jumper (Steven J. Scott, colorist). Sam Jackson is about to walk through a crowd of people. His and their skin tones are accurate, even though their world is a faded, monochrome olive drab.
But back up a few seconds in the same shot and notice that in this faded world, brake lights are perfect, vivid red, and New York taxis read as the correct yellow-orange. This is an establishing shot, and if the grade abused the hue of the taxis too harshly, we might not read “New York” as readily.
Here’s a very short list of memory colors I try to keep in mind when coloring:
People are pink/orange (a color I like to call porange)
Grass and summer trees are green
Water and skies are blue
Fire engines, stop signs, and blood are red
You could also add just about any food to that list. Unless you’re deliberately trying to make something look unappetizing, it’s probably good to render food as accurately as possible—as I’ll show you in a moment.
I welcome your suggestions of other memory colors. And bear in mind that memory colors might vary from film to film and even scene to scene. In Stomp the Yard, there’s a scene at the beginning where almost nothing is red. Later, there’s a red jacket color so important to the story that it leaps out of every scene in which it appears.
So what’s the big deal? Objects have colors, and the colorist makes sure those things stay those colors. Easy, right?
Not necessarily. To achieve the look of that Jumper shot—where key colors pop but unimportant ones blend into a complimentary shade of blue-green—requires practice, skill, and taste. It’s hard enough under the best of circumstances, but lighting, atmosphere, bounce light, flare, camera settings, and a hundred other factors can conspire to force objects to render on-screen in colors quite unlike their real-world hues.
The good colorist first picks the memory colors important to the scene, and then ensures that they stay consistent, often combating these factors to do so.
Here’s a very simple example. I bought some espresso beans today from my favorite local roaster, Blue Bottle coffee. As I was transferring them to an air-tight container, my 7D was right there, so I popped off a quick 720p60 shot of the process—because who doesn’t like seeing coffee beans tumble in slow motion?
When looking at the footage on my computer, I noticed a funny thing. The beans, which in life have a vivid, sumptuous brown tone, appeared gray-black on my screen. I almost didn’t notice, because I know they are brown, but on close inspection it was clear that I had been fooled by my brain into seeing what I knew rather than what was actually there. The cool color temperature of the indirect sun lighting the shot was reflecting off the beans and cooling their color down to near neutral.
There’s nothing unnatural or wrong about this, except that the audience for my espresso epic doesn’t know about the cool light source outside of the frame. They don’t even necessarily know what the falling objects are. I have to communicate that visually, so I need to preserve—or, in this case, recreate—the memory color of perfectly roasted coffee beans.
Here’s the shot with a Colorista Power Mask for just the beans:
And here’s that same shot with an overall look applied after the bean color fix.
To really see the importance of the local correction, look at the shot with the look, but without the bean fix:
Not only do the beans look more appetizing with the fix, they also survive the subsequent look adjustment better. In fact, since the look cools down the shot a bit, the warm color of the beans stands out all the more. Without the bean fix, the look utterly clobbers the brown beans. As a bonus, in the corrected version, the metal canister and the corner of the grinder on the right take on a steely blue color, better matching the viewer’s idea of what color metal should be.
If you pick your memory colors for a scene, and preserve and enhance them through your look, you’ll wind up with shots that pop without looking clobbered by a heavy-handed “preset” look.

Folks following me on Twitter know that I’ve been posting the occasional color correction before/after example there. I’ve now collected them here, including a higher-res version of the coffee bean example.
Today Apple announced the iPad, and what I like most about what we’ve seen so far is that Apple clearly thinks it’s important that we be able to make things with it. The redesigned iWork apps are impressive experiments in creating stuff using a multitouch display. I liked my iPhone enough when it was just a phone, but I love it now that I have Storyboard Composer (formerly Hitchcock), Screenplay, and Photoshop Mobile, to name just a few.
I also use an app called Air Mouse to control the Mac Mini in my home theater. That, and the many other apps that allow your iPhone or iPod Touch to act as control device for your computer, made me ponder the possibility of using the iPhone’s multitouch screen as a control surface for Magic Bullet Looks. But I never took the idea very far because of the small size of the screen.
Folks doing color correction either know first-hand the value of a dedicated control surface, or avoid finding out for fear of the can’t-live-without-it sensation. An understandable fear, given the cost of these peripherals. Back in 2008 when I wrote about gestural interfaces and hardware devices, I expected to spend a couple grand at the very least for any kind of multitouch control device. Video pros routinely spend much, much more for large, cumbersome, single-purpose color control surfaces. Read any review of them and you’ll see one common thread: once you work a three-way color corrector with a set of trackballs that allow you to adjust multiple parameters at once, you never want to go back.
Imagine the dude above is looking at a stripped-down version of the Magic Bullet Looks interface on his main display. The Tool Chain, Preset and Tool Drawers, and touch-friendly Tool Controls appear on his iPad.
The iPad may seem expensive to people with a laptop, a smartphone, and little room in their life for something in between, but for video and film professionals looking for a general-purpose way to get more touchy-feely with their creations, it’s beyond a bargain.
As long as the software shows up.
So what do you think? Is the image above something that interests you? It’s just a hasty concept—nothing more. But it’s got me thinking about all kinds of ways that an iPad could become a part of the way we make films—not just with dedicated apps, but with companion apps that give us new ways of interacting with our favorite desktop tools.

I wanted to thank Przemion in the comments and Vrijegeest on Twitter for bringing hexler.net’s TouchOSC iPhone app to my attention. They are doing this now for audio applications, and even have a free desktop application (Mac and Windows) that you can use to design your own control layouts.
If you’re hanging out with a bunch of editors and you want to play a mean trick on a friend, just find the one guy in the room who uses Sony Vegas (there will be one guy, and only one) and tell that guy that your friend, yeah, the one over there at the bar, he’s super curious about Vegas and would love to hear all about it.
(ProLost, Inc. assumes no liability for what happens next.)
Vegas fans man. They love that Vegas. And they’ll get all up in your blog and be all like, “Dude, Vegas is so underapreciated, and you guys should make Mojo for it, because of all the ruling that Vegas does all the time.”
Well guys, now what happens in Vegas, has some Mojo.
One of my fxphd shots with nothing more than Mojo applied
If you watched my tutorial on achieving the “Hollywood blockbuster look” using various color correction tools, you probably noticed the consistent theme among the very different example films I showed you how to match—the ubiquitous cool shadows, warm highlights look. Whether the film is bleached of all color (like Terminator Salvation) or super saturated (Transformers: Revenge of the Fallen), and whether it is overall warm or cool, modern films have zeroed in on a color correction style that tends to preserve skin tones and set them off against a cooler backdrop.
The same shot before Mojo
It’s more than possible to achieve this look with Colorista or Magic Bullet Looks (check out the Blockbuster preset—it’s been there since day one). But sometimes you just want to spruce up your footage quickly and easily, without a hundred presets to peruse or a powerful colorist’s interface to manipulate.
Sometimes you just want to take your footage that already looks pretty darn good, and give it a little bit of… Mojo.
Magic Bullet Mojo from Red Giant Software is the pocket-sized screwdriver to Magic Bullet Looks’s cordless driver drill. It does one thing, and does it quickly and easily. It gives you that Mojo thang with just a few simple sliders to adjust, and ships with presets for popular looks.
Unlike Looks and Colorista, Mojo is a bit of a one-trick pony. It’s simple and easy and priced to be an impulse-buy at $99 US. One license allows you to use it in Final Cut Pro, Premiere Pro, Avid, After Effects, and Apple Motion [UPDATE: Now Sony Vegas as well!]. Mojo is also now a part of the Magic Bullet Suite.
Mojo has some cool new features that you’ll recognize from the tutorial video. Since it’s all about skin tones, Mojo has simple sliders for emphasizing, cleaning up, and adjusting skin coloration. It even features a helpful overlay that gives you the same kind of skin-tone guidance for which expert colorists rely on their vectorscopes.
Here are some preemptive answers to questions you might have about Mojo:
Q: Isn’t this look just a cheap gimmick? Just a trend that could pass in a few days/weeks months?
A: Maybe, but in another way it’s an evolution of practices many years old in color correction suites around the world. Is it overused? Sure, but that’s because it works. Personally, I love the way it looks, when done tastefully. We provide the tools, you provide the taste. Try turning the Mojo slider down instead of up when you first apply it.
Q: I applied Mojo but my skin tones aren’t popping.
A: Your faces might be underexposed a bit. Try reducing Mojo Balance—it’s the control that determines what’s a shadow and what’s a highlight. Skin tones tend to fall right in between.
Q: I tried the demo and Mojo makes my footage look terrible.
A: Mojo is designed to work with footage that’s pretty solid to begin with. If what you need is color correction, then reach for Colorista. If you love the way your footage looks before Mojo, try the “Mojito” preset—it’s just a little bit of Mojo.
Q: Why do the sliders have more range in FCP than in After Effects?
A: Actually, they have the same ranges, but in After Effects we can have the slider min/max be different from the absolute min/max. I wish FCP would let us do that too, because the ranges we show in AE represent a “sweet spot,” and the values outside those ranges are kind of pushing things into the red a little.
Q: I already have Magic Bullet Looks, why do I need Mojo?
A: Because you don’t open a walnut with a jackhammer. In my own experience, Magic Bullet Looks is occasionally a bit to much overhead for a quick-turnaround project. Mojo is so quick and easy that I reach for it all the time, saving Looks for those occasions when I want to invest some time into my color grading.
