Bring the Sex, AKA preorder Adobe After Effects CS4 Visual Effects and Compositing Studio Techniques



As the author of The DV Rebel's Guide: An All-Digital Approach to Making Killer Action Movies on the Cheap, I can say with some authority that a book should be easier to read than its title. Although by Mark Christiansen's Adobe After Effects CS4 Visual Effects and Compositing Studio Techniques has a longer name than its predecessor, it's for a darn good reason—the addition of the word's visual effects and compositing. Mark's Studio Techniques books have always been unique among After Effects books in their focus on visual effects compositing for film and television.

I had the honor of writing the foreword for AAECS4VFX&CST, wherein I ask and answer the question of why one might want to do such a crazy thing as composite visual effects shots in After Effects CS4:

You’re holding a book on visual effects compositing in Adobe After Effects. There are those who question the validity of such a thing. Some perpetuate a stigma that After Effects is for low-end TV work and graphics only. To do “real” effects work, you should use a program such as Nuke or Shake. Those techy, powerful applications are good for getting shots to look technically correct, But they do not do much to help you sex them up.

Sex them up? Indeed. The central premise of the foreword is that Hollywood is not about reality, it's about glorious unreality—and while there are applications and books that focus on helping you achieve realism, the ambitious effects artist is much better off learning to make things gloriously, cinematically unreal. Sexy even.

“Make it look real.” That would seem to be the mandate of the visual effects artist. Spielberg called and he wants the world to believe, if only for 90 minutes, that dinosaurs are alive and breathing on an island off the coast of South America. Your job: make them look real. Right?

Wrong.

I am about to tell you, the visual effects artist, the most important thing you’ll ever learn in this business: Making those Velociraptors (or vampires or alien robots or bursting dams) “look real” is absolutely not what you should be concerned with when creating a visual effects shot.

Movies are not reality. The reason we love them is that they present us with a heightened, idealized version of reality. Familiar ideas—say, a couple having an argument—but turned up to eleven: The argument takes place on the observation deck of the Empire State building, both he and she are perfectly backlit by the sun (even though they’re facing each other), which is at the exact same just-about-to-set golden-hour position for the entire ten-minute conversation. The couple are really, really charming and impossibly good-looking—in fact, one of them is Meg Ryan. Before the surgery. Oh, and music is playing.

What’s real about that? Nothing at all—and we love it.

You'll have to get the book to read the rest, except that I'll give away the ending:

After Effects may not be on par with Nuke and Shake in the tech department, but it beats them handily in providing a creative environment to experiment, create, and reinvent a shot. In that way it’s much more akin to the highly-respected Autodesk Flame and Inferno systems—it gives you a broad set of tools to design a shot, and has enough horsepower for you to finish it too. It’s the best tool to master if you want to focus on the creative aspects of visual effects compositing. That’s why this book is unique. Mark’s given you the good stuff here, both the nitty-gritty details as well as the aerial view of extracting professional results from an application that’s as maligned as it is loved. No other book combines real production experience with a deep understanding of the fundamentals, aimed at the most popular compositing package on the planet.

What Should Adobe Do With Premiere Pro?


Merge it with After Effects.

Why would I want to see one of my favorite applications bloat to encompass an program about which I am, at best, ambivalent? The answer lies with the post-production ruler of the roost, Autodesk’s “Advanced Systems,” AKA Flame, Smoke and Inferno.

“Do it in Flame” is the battle cry and of producers everywhere who want to get creative work done quickly and well, and leave with a finished product in their hand. “The Flame,” a term which colloquially encompasses Flame, Inferno, and to an increasing degree Smoke, has a reputation for interactive feedback, realtime operation, high quality, and seamless integration.

The interactive feedback comes from a combination of a dedicated disk array and hardware-accelerated compositing operations. “High quality” means up to 12 bits-per-channel color. Integration means that Flame can be used for onlining and mastering, interoperating with NLEs and other systems in the Autodesk family such as Smoke.

Flame has a great toolset. Many of its features are unique, or best-in-class. But many more of them are rather mundane and even behind the times. Still more of Flame’s features are simply odd, having developed within their own ecosystem instead of cross-pollinating with common entry points to digital compositing such as Photoshop and Shake. While a bit convoluted, Flame is a unique and accomplished tool that deserves its stellar reputation.

But some of the mystique that surrounds Flame is more perception than reality. Yes, you can play things back in real time—after you render them, a process which can sometimes be hardware accelerated, sometimes not, especially at high bit-depths. And those high bit-depths are not as high as the 16-bit integer color common to most inexpensive desktop solutions, such as After Effects and Fusion. Flame notoriously lacks pervasive floating-point color support, a feature ubiquitous at every level of compositing from Apple’s Motion to The Foundry’s Nuke. As integrated as a Flame might be into a facility’s post pipeline, that often simply means that it depends greatly on supporting players such as Avid, Smoke, or the kid in the back room with Photoshop, in order to appear as a complete solution to the client.

The other reason for Flame’s excellent reputation is that its high cost commands an equally high-value operator. The biggest perceived value of the flame is its speed and interactivity, but these qualities rest more on the artist’s shoulders than on the system itself. Flame and Smoke do need to render. Their many hardware-accelerated features do not often add up to to “real time.” Flame artists learn the same kind of client-management skills that colorists and offline editors master: They read the vibe in the room, tweak things when the attention is on them and disguise the subsequent rendering (which Autodesk brilliantly rebadges as “processing”) with well-timed chit-chat. “Where are you guys going to dinner tonight?” “Anyone want these Lakers tickets? I can’t use them. OK, here’s that new version…”

And once you render, you’ve got a new asset that you must decide to either build on destructively, which is tempting because of the speed but possibly disastrous if the client asks to dig back several layers for a change. Or you can work in “batch,” where you have the same kind of issues that every After Effects user faces, in that each tweak prompts a complete recalculation from square one. But for that price you maintain infinite flexibility. And incur the need for a render farm, which heavily-Flame-dependent shops do maintain, at great cost.

The inarguably great thing about Flame is that it is a responsive environment in which to be creative. While some VFX tasks require relentless hammering on a known set of assets (the domain of Shake and Nuke), some require more purely creative problem-solving. What should this effect look like? We need to add pizzaz! We really need something cool here and we didn’t shoot anything—what do you have lying around? Flame is a great tool to build, create, design, and experiment.

Does that sound familiar? It’s exactly what I love about After Effects.

After Effects is also a great creative environment. It’s got all kinds of fun tools and ways of making something out of nothing. It’s intuitive, especially for simple things, and plays nice with Photoshop and Illustrator. It wobbles under the pressure of high-end compositing, but it goes toe-to-toe with Flame for creative problem-solving.

What it lacks is Flame’s trademark interactivity. Not being able to enforce a specific graphics card, After Effects does very little with the GPU. Even on a system capable of realtime playback of, say, a 2K DPX sequence, After Effects requires you to RAM preview, and those RAM previews can be slow to build and fragile to view.

I recently visited an Orphanage artist who had temped together some effects shots for a feature film using After Effects. He had all the shots in one project, each shot a precomp conformed into one master comp that matched the cut from editorial. This is a very common thing to do in After Effects, something I do all the time: using the layered comp as an editorial timeline. It works, but it’s a hack. And in this case, it was a rather fruitless hack, as the guy’s machine didn’t have enough memory to hold a complete RAM preview of that lengthy comp. The artist had the right idea, to create a context in which to constantly check his animation, but it just didn’t work.

All day long he’s working in the individual shot precomps, at whatever resolution and quality settings he finds efficient. And every once in a while he wants to view his work in context. For that, he could be working compressed. He hardly needs uncompressed RGB for a quick little review of the cut. Instead, he tweaks one shot and returns to his timeline to find that he must re-render ten shots that he hasn’t touched. He might want to play with things editorially. For that as well, a true editorial timeline would be preferable to a stack of layers that aren’t really stacked.

That conform timeline should be NLE-style, with an implicit, user-selectable codec. The rendered previews should be cached to disk rather than held in RAM. In other words, that timeline should be Premiere Pro’s.

Adobe would suggest that you can do this now using Dynamic Link. You can indeed have a live connection between After Effects and Premiere. It’s a cool idea, but in practice it doesn’t work. It breaks when you do common things like iterate a project name. You wind up re-rendering in Premiere a lot, and when you do, you trigger expensive After Effects re-renders. Dynamic Link is an implementation of an obvious idea, not a bourne-of-need workflow enabler. You will only ever see it demoed with the very simplest of After Effects compositions, because with anything substantial, it becomes unbearable. As I’ve mentioned before, the only reason to use After Effects instead of cheaper, simpler options is to do something substantial.

We need seamless integration between the uncompressed, limitless-but-slow world of After Effects and the realtime environment of Premiere.

Rather than RAM preview an After Effects comp, you should process it to a clip, in the codec of your choosing. Every time you RAM preview you can either write over that clip or create a new one. A clip maintains a connection with the After Effects composition that created it, and knows if it is no longer current. It can display a little warning icon if changes have been made in the comp that have not yet been rendered.

Those clips are real media that you can use, re-use, edit with, and play back in realtime months later.

And they can be nested into a complex editorial timeline, where today they live as a DV temps and tomorrow they gets bumped up to uncompressed HD finals.

Because that codec of your choice could be anything from DV to uncompressed HD to 10-bit DPX.

The Premiere side of the equation would naturally adopt the complex but powerful color management features of After Effects. You’d be able to edit uncompressed DPX in a Premiere timeline and preview with a Kodak Vision 2383 film stock emulation. Heck, preview it with 2393, more commonly known as Kodak Vision Premiere!

This arrangement would let you work the way a Flame artist does, constantly able to weigh the benefits of power and speed. Just need to retouch a frame? Go ahead and paint on your last render. Need to dig back to the very bottom layer? Do so knowing that you can re-render everything above it and get the same results as before, plus the fix. And know that every time you process a clip and update it in your timeline, you’re building a realtime HD program that you can blast out to a client monitor, or a deck, or to Adobe Media Encoder. Combine this with speculative background rendering (ala Nucleo Pro), and you have a very powerful system. And this system would run just as well on a laptop as on an eight-core Mac Pro—the only difference would be the codec you’d chose.

Now maybe all of this doesn’t require the After Effects dogs and the Premiere cats to live together. Maybe Adobe doesn’t need to make the two programs into one. But there’s not a single After Effects user who couldn’t benefit from a realtime editorial timeline. Nor is there a single Premiere user who hasn’t wished for a feature that already exists in After Effects. In other words, whether After Effects and Premiere literally merge into one product SKU is not important—what is important is that, to someone with both applications installed, the option exists to use them together in such a way that the distinction between them blurs away completely.

If only there was some kind of application that existed specifically to “bridge” the Adobe Creative Suite apps together… Hey, what’s this thing taking up 400MB on my hard drive?


Maybe it’s through Bridge, maybe something else, but what we need is an Über Project that can contain both Premiere and After Effects assets and show how they are connected. I imagine it looking much like Flame’s “Desktop,” which is a sort of media home-base in Flame that serves as everything from a clip browser to a reference library to a convenient place to scratch your chin and ponder your next move. You wouldn’t be the only ones looking at this. Have you seen Eyeon’s Generation? Have you seen how much they’re charging for it?


However you do it Adobe, you gotta do it. Sure it will be hard, but only for reasons that would be wrong to base important decisions on. If you do it and do it right, you put a Flame in the lap of every one of your Production Premium customers. You can stop wasting precious development efforts (so much more precious now that your development cycles are shorter) duplicating functionality between your two flagship moving media applications. You’ll force Autodesk off their laurels and get them innovating and competing again. You’ll finally make it possible to host a client-supervised compositing/finishing session with Adobe software. You will put one and one together and the result will be three.

AE CS4's Best New Feature is Backwards

The details of the next release of Adobe After Effects are now public. AE CS4 features 3D object rendering (objects come in via Photoshop CS4 3D documents) and a full seat of Mocha AE. But my favorite new feature is more subtle than that. It fixes perhaps the biggest problem with After Effects. And out of the box, it's backwards.

 

In order to do real compositing work in After Effects, you frequently must precompose, creating nested relationships between compositions that can become quite complex and deep. Navigating these relationships can be the least fun aspect of working in After Effects. Taking over someone else's After Effects project is notoriously difficult for this reason. Half my time looking over an After Effects compositor's shoulder is often spent watching them search desperately for which tab, which alphabetically-sorted comp contains "the place where I did that."

CS4 adds a new feature for rapid, graphical navigation of nested comps. It's called the Mini-Flowchart, and it resembles the After Effects Flowchart View that was previously the only visual way of browsing the relationships in an After Effects project. No one ever uses the Flowchart View, because its half-implemented status punishes you for doing so. But it's a good idea, and the Mini-Flowchart extracts some of the best things about it. It's a little slice of nodal goodness integrated seamlessly into the slick new CS4 user interface.

But did I mention it's backwards?


As you can see, I have four source comps that I'm using in Main Comp. I then have two different output comps, HD and SD. But if you're like me, the flow is backwards here. The sources are on the right and the outputs on the left. The arrows show that images flow from right to left.

The theory is that you might view your After Effects comps as nested folders, and like the NEXT-inspired column view in OS X, your top-level directories are on the left and your deepest-nested assets are on the right. The problem is, nested comps are not files and folders. You can have a footage item that is deeply-nested from one comp and used directly in another. You can't do that with files and folders.

But more importantly, compositing is not storage. It's defining a process. After Effects projects are lists of instructions, and the ones that happen first belong on the left, the ones that happen last belong on the right. At least in countries that read left to right!

Luckily, if you agree, you can fix this easily enough. Just click the wing menu and select Flow Left to Right.


Much better. Source on the left, output on the right. Arrows flowing patriotically. If, like me, you hope that AE will someday do more with nodes, this would be a good change to make (you only have to do it once). Obviously, nodal systems tend to flow left-to-right and/or up-to-down. It's a bummer to me that Adobe chose right-to-left as the default—it feels like it puts more distance between me and a nodal future for After Effects.

But whether you roll left-to-right or right-to-left, the Mini-Flow is wicked awesome. You access it with a button in the Timeline, but better still you can bring it up with a quick tap of either Shift key. You can then easily navigate it with the arrow keys, jumping into any comp by hitting Enter. Trust me, before long you'll wonder how you lived without it.
