Compression Artifacts & Pulldown

A question about a ghost leads to discourses on 3:2 pulldown and the QuickTime codec dialog.

This started as a quick post about how to gain finer control over the compression settings in the QuickTime dialog. But before we can get there, we first need to talk talk about how 3:2 pulldown works. (Trust me; it all ties together; it was also a good little mystery.)

I recently gave a training session at a local studio, and at the end they were invited to trot out their Barney Stumpers (questions about why something went wrong, how something works, etc.). For one stumper, a user had some footage with 3:2 pulldown, and after pulldown was removed, he noticed that an after-image of the previous frame appeared in the next frame after an edit. Why?

A Distorted View of the World

A case study of why it’s crucial to plan just how you’re going to move between 16:9 and 4:3 worlds.

One of my vices is auto racing; I love to watch it. Which, of course, means that Speed TV (formerly Speedvision) is a requisite part of my satellite or cable TV package. Speed is owned by Fox Sports; you’d think there’d be some budget available, and some standards enforced. But every now and then, they put on a program that makes me wonder just who they’re hiring to do their production. (See my previous blog post Staggering Mistakes for another shining example.)

One recent program - a preview of a Formula 1 event - had me stumped for days trying to figure out just how in the world they managed to mess up the image that much (the result of which is simulated here). Here’s what I think they did:

Rethinking the Music Video

What if the graphics in a music video were driven by the music, instead of a filmmaker?

At last year’s TED (Technology, Entertainment, and Design) conference, Jakob Trollback - director of the highly innovative motion graphics studio Trollback+Company - gave a talk and showed a sample of a different approach to take for music videos. His idea is that the video could and should be an expression of the song, not an expression of a filmmaker’s high concept, or for that matter the low concept of MTV demographics. The video above realizes this vision with the song Moonlight in Glory by David Byrne and Brian Eno from their groundbreaking album My Life in the Bush of Ghosts.

Trollback isn’t the first to take this approach. Imaginary Forces created a legendy piece honoring film soundtracks for the Oscars which also used abstract graphics apparently motivated by the music, while even earlier Digital Kitchen made a great piece for Sony’s digital theatre sound system which was very similar in flavor to the piece above (if anyne can dig up a link to video of either piece, I’ll add it here). But it’s an interesting, thoughtful approach nonetheless.

mocha AE to CC Power Pin

Using Animation Presets and Expressions to simplify using CC Power Pin instead of Corner Pin with mocha AE.

Imagineer Systems’ mocha AE is a stand-alone planer motion tracking application that creates keyframe date which you can in turn use in After Effects. If you are performing a perspective-style track, you will paste the resulting data into a Corner Pin effect already applied to the to-be-pinned layer in After Effects.

However, some prefer using the CC Power Pin effect that comes with Cycore Effects (bundled free with After Effects) over the stock Adobe Corner Pin effect: It is more flexible, and some feel it resamples the layer with higher quality. As a result, a number of workarounds have appeared to apply mocha’s Corner Pin data to CC Power Pin. I’d like to share a couple, and add my own.

Multithreaded Information

Is the medium really the message? Or should we think more about matching the message to the medium?

(At the end of an old article we recently posted to our Keyframes channel about creating graphics for the NBC AstroVision sign in Time Square, we mused about the ways networks are trying to take advantage of new media to connect better with their audiences and create more brand loyalty. Even thought it was originally written ten years ago, it still resonates today. I thought I would drag it out here for your weekend musing, in case you missed it over in CMG Keyframes.)

One of the original attractions of “multimedia” was the ability to provide additional details and background information about a subject without forcing interruptions in the linear unraveling of the central narrative (as I do here with my frequent parenthetical asides). Examples of this include allowing the user to click on hot words or photos in a CD-ROM application (do any of you still remember those?) or on a web page to take you to another page with tangential content, or attempts to present multiple media streams at once - such as text, photos, and sound - to give a wider gestalt to the story.

So where does established, linear, big media - i.e. broadcast television - fit into this picture? Although the economics are different, many of the same goals applied, even ten years ago: You have a linear central story (the program), but other details you could provide...even something as simple as outtakes from filming the program, or background on the stars. Fan magazines, newsgroups, web sites, and even TV Guide help fill this roll. NBC, in their own way, started doing the same back in the late 90s. For example, their “NBC2000” group was one of the first to put the alternate screen boxes at the end of television shows, sometimes containing outtakes or promos of other programs. With their AstroVision sign, they went further.

Initially, NBC tried “repurposing” their existing TV promos onto the sign. However, as many multimedia producers also found out back then, you can’t always take a message from one medium to another and expect it to hold up. In this case, the lack of sound, as well as the differences in attention span between someone at home and someone in Times Square (or Epcot Center, or sporting events, where they also play these promos), rendered the original promos less effective than they were on TV. In response, NBC started designing alternate content for the sign - such as trivia puzzles, word games, and factoids about their stars. Each one is then followed by a few seconds of the program the star appears in, along with the name of the show, television network, and night it plays. It ain’t exactly a hot link, but it does give you the pointer you need to follow up on a thread you might have found interesting. And if you’re already a fan, it gives you some additional background information to widen your experience of the show.

It wasn’t the “grand convergence” many preached about back in the 90s (or even today), but neither was it a bad idea - especially for the time. I know it is still popular to say the medium is the message, but perhaps some of us would be better served by focusing more on the message, and then figuring out how to use the mediums at our disposal to better disseminate it.

NAB 2008: Plugged In

We came away with three themes buzzing in our head: plug-ins, training, and Nuke.

As expected, NAB 2008 did not reveal any major new software releases for motion graphic designers, but it did showcase a number of interesting new plug-ins. We’d like to give you a quick round-up of our favorites here; we’re arranging to give many of these more in-depth reviews up here on PVC over the next several months. We also were very interested in with what The Foundry has done with the high-end compositing application Nuke (which they acquired from Digital Domain), and came away with the impression that in this slow economy, training has become more important again.

We’re Off To See The Wizard

NAB always brings the promise of finding that secret ingredient we need to make us better at what we do.

It’s been awfully quiet around here lately...too quiet. But you know why: It’s the week before NAB (the National Association of Broadcasters) Convention, the largest annual industry trade show for those of us in North America), and we’re all hunkered down either a) finishing projects before NAB, b) getting our presentations ready for NAB, c) making out our shopping lists for NAB, or d) all of the above.

You Are What You See

A recent study reinforces how important it is to carefully choose the elements we use in our graphic designs.

This Saturday on NPR’s Weekend Edition, there was an odd little piece about a study performed by Duke University about people’s reaction to logos (click here to listen; click here to read a text article about the same study). It said that being exposed to the Apple logo – so briefly that they couldn’t even register what they had just seen – caused the subjects to then become 20-30% more creative, while being exposed to the IBM logo caused them to become more competent and professional - or at least, acted that way on a test they took immediately thereafter. (The same study also concluded that people exposed to the Disney logo went on to behave more honestly than those exposed to the E! Channel logo.)

No, the point of this is not to start another flame war between Apple and PC users. And yes, I’m familiar with “blipverts” and other forms of subliminal advertising. What struck me was how important imagery we use – even subtle, background imagery or images that are not on screen all that long – may influence our viewers when designing a show open, informational graphics, or other forms of motion design. We always try to think through things like color, pace, and the calming versus threatening nature of imagery we use when designing motion graphics to evoke a certain mood or reaction, but the results of this study have made me even more hyperaware of it.

(While lying there listening to the program, I was also reminded of the William Gibson novel Pattern Recognition where the heroine was actually allergic to branding. She made a living off this talent from companies who hired her to see if their new logos made her sick – if so, they had a winner!)
