So You Want To Learn 3D? How to bring the stereoscopic dream to life

It’s been a long journey into the realm of 3D documentary filmmaking for myself and the rest of the Parallax team.

A rugged path marked with a few big wins – triumphs earned via epic missions through a series of formidable stereoscopic obstacles.

The good news: we’ve trampled a rough trail … a trail that will hopefully help other enthusiasts avoid getting too thoroughly lost in the enchanted forest that is 3D production.

Our stereographer, Sean White, details some quick and dirty ways to follow us into the third dimension.

Immerse yourself

Learning 3D is a full-time job. A solid foundation of stereo principles is needed if you want to succeed

Research. Take an introductory course. Enlist the help of an experienced stereographer.

Or for true 3D keeners, deconstruct a ready-made system into its basic components. Best way to master the beast. Hands down.

Start small

Our first foray into 3D filmmaking was a modest one involving two $20 cameras purchased on EBay and mounted on a side-by-side rig.

Starting small makes getting bigger the only option.

Experiment

Always think of ways to make your 3D system better. Tinker, take risks, and invent.

Capitalize fully on your mistakes by knowing exactly where you went wrong. Leave no error unturned.

Share your failures and successes with other experimenters. Best way to avoid epic catastrophes.

Keep your eye on the prize

Driving your whole 3D pursuit is the desire for results – not only should you want something properly stereographed but something beautifully stereographed.

Keeping this in mind, never forget to reverse calculate . . . knowing what you want in the end means taking purposeful, well-thought steps to get there.

Alright, that about does it … now it’s time for the good stuff:

Get out there, get dirty, and above all, have fun.

Making a 3D documentary: 3D TV penetration stats

Fun with numbers … 3D TV style. As we get ready to shoot our first 3D documentary, I’ve been curious about what the future holds for 3D TV.

It’s tough to find stats on this, but I did come across a report from the International Television Expert Group, released in May 2010.

The report forecasts:

1) Over 20 million TV homes globally will be watching 3D TV within five years.

2) 3D TV is expected to be in 1.6% of all homes by 2015.

3) North America will lead the way in terms of number of 3D TV homes with 9.2 million.

4) Western Europe will be the second largest region with 6.8 million.

5) Asia Pacific third with 4.6 million.

It predicts growth will be constrained by:

1) Absence of a glasses-free system of watching 3D TV.

2) Lack of content.

3) High production costs.

4) Scarcity of channels.

5) Bandwidth constraints.

6) High cost of 3D sets.

Obviously, the more people who get to watch this next episode of the explosive demolition series Blowdown we’re about to shoot – the implosion of the Fonte Nova Stadium in Salvador, Brazil – in 3D, the better.

Has anyone else come across stats on 3D TV penetration?

It would be great to see more …

 

Making a 3D documentary: stunning visuals, solid story

It’s the final countdown. Our stereographer, Sean White, is hustling to nail down all the gear to shoot  our first 3D documentary.

The crew will be packing up on Sunday, and flying to Salvador, Brazil on Monday to start filming the explosive demolition series Blowdown – plan to get get lots of pics and video of the gear before they leave and post here next week.

I’ll be joining them the week after, and will stay until after the implosion of the condemned Fonte Nova Stadium.

And while Sean and the others are busy thinking about how to capture great visuals in 3D, I’m going to be thinking about story.

Even though all this 3D stuff looks incredible, I still believe that if the story isn’t good, it’s not worth watching – so I need to make sure we’re investing in it first.

This means capturing key bits between Controlled Demolition Inc.’s crew – obstacles they encounter, conversations they have, and emotional moments that resonate.

On the other hand, I don’t want to be afraid to capture 3D footage that will captivate our audience visually …

Shooting a 3D documentary: thinking 3D in the field

As our first 3D documentary shoot approaches, I’m contemplating the intricacies of shooting in the third dimension. Our stereographer, Sean White, is familiarizing the rest of the crew with the new things they’ll have to take into consideration when shooting the prep and implosion of the Fonte Nova Stadium in Salvador, Brazil.

Bottom line: the jump into 3D will change how we frame and shoot the explosive demolition series Blowdown.

In other words, it will change pretty much everything.

And to make it work, the crew’s going to have to learn how to “see” in 3D.

They’ll have to think about where things are going to fall into positive and negative space.

They’ll have to identify visuals that are going to look superb in 3D – and, just as importantly, recognize the shots that won’t make the cut.

They’ll have to understand the strengths and limitations of each rig – our beam splitter, mini beam splitter, and the plethora of side by sides – so they know which one works best for which shot.

They need to recognize when we can’t get too close to a subject.

They must realize that they can’t frame something in the extreme foreground and pan to reveal a subject in the background – a trademark move to help create depth in a 2D image can mean too much volume in 3D.

They also need to make sure there are no objects floating around in the foreground (ie. wires, the edge of a wall, rebar sticking up, edge of a concrete slab) – and understand what details could be distracting.

Not to mention they’ll be working on a dusty demolition site – for example, excavators pulling up dirt, swinging into the shot as the “claw” grabs something.

They’ll not only have to think about how this will play in 3D, they’ll have to think about if one lens is dusted out, say, by the excavator’s load.

If they miss any one of the parameters on any one of the eyes this shot – or any other shot – will be useless.

Here’s to cleaning the cameras – times two.  And all the adventure that comes with it.

Lucky we have a great crew. Ready to roll.

Shooting a 3D documentary: why we use still photography to capture time lapses

A bit more re. how we plan to produce time lapses for our first 3D documentary.

We’ve used still cameras to capture time lapses for previous episodes of Blowdown, the explosive demolition show we’re gearing up to film – for transitions, establishing shots, and work that’s progressing.

Here’s a raw example of one from an episode in Season One – the implosion of four cooling towers at the Sellafield nuclear facility in England:

The reason we use this technique is because it gives us photos that are higher resolution that HD – pristine, jpeg images up to 21.1 MP.

Obviously much better quality than frame grabs off of video.

It also means our primary video cameras/crew can be used to film action – in this case demo work on the Fonte Nova Stadium in Salvador, Brazil – while the still cameras (in this case Canon 7Ds) sit unmanned on a side-by-side rig, automatically collecting shots.

In the 3D realm, the super high resolution will allow us to converge and do digital zooms in post within the time lapse without losing any quality.

Shooting a 3D documentary: how we’re syncing Canon 7Ds (VIDEO)

Yesterday’s post has created some confusion between syncing Canon 7Ds for 3D time lapse photography and syncing them for 3D videography.

I’ve edited to make clear yesterday’s post is for stills, and am now posting re. video.

To sync Canon 7Ds while shooting film footage for our first 3D documentary we plan to use the same infrared box systems we’ve rigged to sync our Canon Vixias, and slate our shots so we can sync in post.

I’ve outlined this technique in previous post for Vixias. For 7Ds we:

Set both cameras to self-time/infrared mode, which allows us to use an infrared remote (The Canon RC-5, in this case)

Position our box designed to receive any infrared signal and transmit it through a split cable to two infrared sensors.

Tape the infrared heads at the ends of the split cable to the infrared sensors on the two Canons and then use the remote to start them in sync.

And yes, because of the internal clock circuitry disparities we don’t get a 100 per cent accurate start and stop, as the cameras may not start recording on the same frame.

Our stereographer, Sean White, has found our 7Ds can be out of sync by one or two frames at 30 FPS.

To get around this we’re doing a physical slate at the start of each shot for our editor – this way he can toggle shots by a frame or two and sync from where the slate is.

Sean’s tested this system extensively.

He’s found that once you sync clips at the start they stay in sync for up to 12 minutes straight – much more time than we need to get the types of shots we’re going to capture with the 7Ds.

Video: Compositing for a 3D documentary – VFX elements that work in stereo

The 3D VFX pyramid fly-in shot that our compositor’s been working on to test techniques for our first 3D documentary is good to go.

Again, you’ll need the good old red-cyan goggles for this:

Our compositor, Jakub Kuczynski, explains elements in the shot:

And compares working on 3D VFX versus 2D VFX:

This shot will be part of the 3D demo I plan to show broadcasters next week.

Now all I need to do is find a 46-inch JVC monitor to show it on …

Shooting a 3D documentary: how we’re syncing Canon 7Ds (STILLS)

I’ve received a few questions re. how we’re syncing Canon 7Ds we’re using to capture elements of our first 3D documentary … so I’m blogging about it to share with everyone.

We’ve used DSLRs to get high res stills at set intervals for time lapses for years, but, of course, never in 3D.

For this 3D episode of Blowdown, the explosive demolition series we produce, the crew will use 7Ds for these time lapses – and also for establishing shots of the condemned sports stadium in Salvador, Brazil and, of course, the implosion itself.

Here’s how we’ve brought this system into the third dimension:

1) Splice cable so there are two heads on one intervalometer.

2) Attach heads to timer remote ports on two Canon 7Ds on side-by-side rig.

3) Sync using the one handheld intervalometer.

Voila!

I’ll provide more details re. our time lapse strategy later: wanted to get this bit up ASAP.

Hope it helps.

 

VFX compositing for a 3D documentary: compiling a demo

As we prep to shoot our first 3D documentary, our compositor, Jakub Kuczynski, is getting ready to produce 3D VFX for the show.

We use these photo-real visuals in the explosive demolition series Blowdown, which we’ll be filming the next episode of, mostly for:

1) Locators – help orient the audience and show where the crew is working at a particular point.

2) Disaster scenarios – show the audience what will happen if different aspects demolition plan go wrong.

3) Dynamic structure shots – fly-overs, fly-throughs, fly-ins … allows audience to experience the strength, grandeur and engineering prowess of structures that Controlled Demolition Inc. implodes.

Here are two examples from previous shows: Super Stadium and Spyship:

Locator VFX: RCA Dome. Indianapolis, Indiana

Disaster scenario VFX: Hoyt S. Vandenberg. Key West, Florida

As part of this process, Jakub’s generating sample 3D VFX shots so we can assess them and so I can take some on my trip to meet with broadcasters the week after next.

We’ll combine the 3D VFX clips with some of the 3D test footage we’ve shot so I can give the broadcasters a solid visual idea of what we’ve developed so far.

One of Jakub’s shots – a fly-in to pyramids.

Why I’m including this in the 3D demo:

Look forward to the final.
