Print view

Amateur filmmaker Marc Donahue of Permagrin Films recently shot a video with an array of fifteen GoPro action cameras to achieve Matrix-like bullet time special effects. The arc-shaped rig allowed him to shoot simultaneously from all cameras. In post, Donahue added the freeze frame and slow motion effects.

There are several videos on Marc Donahue's YouTube channel demonstrating his experiments with the action camera. Also check out the Donahue's interview by FStoppers where he talks about the pre and post -production work and challenges involved. (via Mashable)

This is an illegal video, the process used is patented by Digital Air
http://www.digitalair.com/licensing_commercial.html

They own a patent that says if you take a picture form a frame by frame media (which to you and I is video), then it is theirs.

The only way to do bullet time without contravening their patents, is by using single shots from still cameras.

Let me get this straight, you take the idea that has been done many years ago, has been perfected in major movie productions, you wait a few years, take a few cheap cameras, do it over, just poorly and then people say, 'so cool', 'such a great idea'. Alright :)

Why do you have to be so bitter? Are you not getting enough attention?

@cacv12000 When I saw the headline I actually got excited and was looking forward to seeing it. I was just disappointed by the poor quality. The cameras were poorly synced and the overall quality wasn't impressive. The hands and feet wobbled when the actual idea was to freeze the moment and have the camera track in 'bullet time'. Overall the quality wasn't that good either. Just funny to see people say 'great imagination' when the neither the idea is original nor is the execution well done. Well done on GoPro's marketing, thought :)

0 upvotes

Wasn't the idea that it was done so cheaply?

0 upvotes

This has been done before quite a few times.

Including early last year a whole launch campaign for a big surf label (I can't remember, but I think it was Quiksilver) was shot entirely with exactly this technique.

they set up scaffolding in a wave pool and at actual surf breaks to mount the Go Pros on.

There is great behind the scenes video of it on the web.

The operators they had computers on set for visualisations also.

Very cool stuff.

From a purely artistic point of view this was impressive and fun. But the question that comes to mind is this: Do you really want to have reality distorted so much? It may be good for a quick thrill but is it good for the spirit, good for the soul and good for the historical memories we leave behind?

yes. It helps to understand Einstein's relativity theory.

Great effort - achieving effects like this with a low budget will inspire others. In a few years we will be seeing a whole new wave of cinema, with low budgets and great results (and a shitload of crap, of course). Isn't that what every filmmaker dreams of?

Thanks. So how does Timmbits explain this? Doesn't seem to be any shutter lag or inconsistency here? These guys got lucky?

0 upvotes

That's the one I was talking about, thanks! Yeah, aside from the distortion from the water on the lens, their bullet-time is nice and smooth. I'm curious to know what caused the difference in quality between the two videos, and I'm really curious how Rip Curl worked with their video in post: I don't think it's just a matter of taking one frame from each camera, I bet they use some sort of morph transition or something to create that smooth motion.

Good idea, but I agree that it's a bit too herky-jerky. I remember a surf company did this a few years ago but with alot more (30 or 40 if I recall) Gopros, and it looked really good (I'd post the video if I could find it), and didn't have that "twitch" effect that this one did.

I've been wanting to do something like this for a while now, my hope was to try it with iphones (since almost everyone has an iphone), though I'd imagine it'd still be a bit of a hassle.

Good ! -Did anyone ask, exposing the brand-name of equipment used THAT MUCH ? A kind of "deal", coupled to the number of "clicks" on this clip, would do the trick here. I do not express any suggestion of the existence of such a deal here, but do point at the rather obvious possibillity of it...

I'd love to see links from the critics of their own film work. This is brilliant.

To be honest this is a fantastic effort on a budget of zip.

It's interesting that Marc uses the GoPro as he'd be shooting video with each rather than a series of stills - which opens possibilities to editing motion within the Matrix effect.

I think the comments about motion artifacts may be confused with the "scratch" editing within the action. We've got some interesting forwards and backwards motion of the subject whilst the tracking motion continues in the same direction. This is the first time I've seen this and kudos to Marc for coming up with a variation on a well known effect.

And to the critics of the execution... please send us your examples - we'd love to see how much better your versions are...

2 upvotes

Unless GoPro supplied the cams, it was hardly a budget of zip. Each goes for about $399.00 (Amazon Hero 3 Black) so we are looking at about $6,000 not counting any other materials that were used.

I think main Go pro problems is the lens distortion.
They need to reduce this.
so the videos look better.

As stupid as this will sound, GoPros need to be fish eye lenses to catch all the action. When you are surfing or skydiving optical optimization isn't really as much of a priority as just getting the footage.

One place GoPro really does need to improve is with sound. I want to record my motorcycle rides and GoPro's mics are terrible in that regard. They pretty much don't capture anything below 100Hz, I am guessing to minimize wind noise.

2 upvotes

@sportyaccordy, record audio separately and sync it later, get a simple recorder like a Zoom H1n with a foam windscreen or deadcat on it and put it in your backpack and set it to 48/24 or 48/16. It still might be too windy. Maybe a super fuzzy backpack would work, and don't let the recorder touch the walls of the backpack, make it suspended in there somehow. Or put it inside a fuzzy seat bag on a shockmount. I've always wanted to try that. Your bike will probably be loud enough to hear through all the wind protection. What kind of bike is it?

If by "film cameras" you mean movie cameras, you'd be wrong. The original Matrix movie used Canon Rebel SLR still cameras. At the time, these Canon SLRs were loaded with film, but the subsequent Matrix movies used digital Rebel DSLRs. BTW, one of the reasons why they used Canon Rebel DSLR is A) the Rebels used standard mini stereojack-style electronic cable release, B) they were inexpensive. Other brands, as well as Canon's own higher-level DSLRs, didn't use minijack remote connectors.

I believe they used Canon A2.

Shutters weren't synced properly (see motion flickering between frozen images), but a good start. Can go pro be triggered externally?

I think that it is apparent that the producer made that in purpose.

Whether the flickering effect was nice or not is another matter.

it's quality inconsistency... some of the GoPros had more shutter lag than others

Concept gets an A, Execution gets a D. Keep after it though, this could be very interesting. Though i have seen a couple of other people try it with the 1 and 2 with similar, semi good results.

..and all it takes is a SINGLE camera:

5 upvotes

Not really. The device you linked to permits a visually similar effect, as long as your subject's path is completely predictable, and you don't mind re-shooting if you don't get it right the first time. But if you're capturing live action and you want the footage of an event as it happens, you need multiple cameras.

It's also not clear whether their custom robot is actually a product available for purchase, or whether it costs more or less than 15 cameras.

Lastly, as to the quality - good points, but I don't think his purpose here was cinematic quality. It was proof-of-concept. Sure, now the question is, how good can it get?

1 upvote

@JamesInCA - yes, what I linked is a wholly different league,
here's a behind the scenes movie:

http://www.youtube.com/watch?v=A2CLQdCU7O0

But I'm sure something similar could be built with an amateur level budget as well - without all those bells and whistles like a professional 3d modelling interfaces and stuff like that..

@wlad
Amazing. I have always thought those clips are CGI.

1 upvote

@Peiasdf I think most studios do use CGI for effects like those, but it seems this german studio can accomplish similar effect with a single high speed camera mounted on a robotic arm.
As a geek, I'm impressed :)

1 upvote

@wlad, thanks very much for sharing that.
very impressive!!!

but you have to concede that it's not the same thing. in that video the robot is making the camera move faster than the subject, and it is a very very very expensive setup ($200k for the robot, maybe?). whereas the gopro thing is rather low budget in comparison. would have cost even less if they had used standard wide angle regular cameras (many small cheap portable ones on the market to choose from).

The only property I could see was the one that meant they couldn't actually get all the shots perfectly sync'd. I found the slight "judder" somewhat distracting.

Gopro is great if you need waterproof and wide angle. Not sure why this guy even used gopro 3 models since any cheap little cam that shoots video can do this. Some videos needed the wide angle, but most didnt appear to need it at all.

1 upvote

for this video, nothing special about gopro - you could use just about any camera to do this. (it's the same marketing tactic that apple has been doing for decades now "look at what you can do with apple" and people automatically conclude that you can't do that with any other computer)

this is merely their marketing team finding ways to use a camera, showing it being done with a gopro, and then using social media to get free advertising for the brand. (youtube, fb, vimeo, camera-centric websites like this one)

Also I see some timing glitch

1 upvote

the timing glitches are quality inconsistencies in the cameras. some have more shutter-lag than others.

1 upvote

Actually, I think the timing glitches are a result of the cameras not being genlocked. They're shooting fast, but not fast enough that you can get perfect syncronization of the frames in time domain.

That's what makes this cool - you don't have to have a set of computer synchronized SLRs to create a limited bullet-time effect.

1 upvote

Would be really cool if the shutters were triggered by a massive signal from a singular device than from a wired switch.

Cool concept. Many will surely follow.

3 upvotes

electrons travel at about the speed of light... no matter how long the wires are, a meter or 10 meters, they'll still make the cameras fire at the same instant.
the problem here is inconsistencies in the cameras themselves. some just have a longer shutter lag.

Amazing. Well done!
