## Step 2: Dimension

The shape of the arc you will need to cut depends on the kind of shot and the amount of rotation around the subject you wish to achieve. As mentioned in Step 1, our plan was to create a 180 degree rotation around a subject that will be in the frame primarily from the waist up. Keep in mind when deciding on the amount of rotation you desire that at some point, some of your camera cameras will be able to see your rig in the shot (at 180 degrees for example the two end cameras will be faced directly at each other). There are ways to minimize and mask this but it is worth considering when designing your platform.

Because the focal length of camera lenses will vary it is best not cut your rig to specific pre-scripted dimensions but rather test on your cameras to find the desired shot. Have a subject stand at a distance from one of your cameras (make sure the camera is zoomed all the way out). When you have the desired framing in the lens then measure the distance of the camera to the subject. This will be the radius of your camera arc. Keep in mind that you are not limited to an arc and if you have rigging material more flexible then wood you could even reshape the rig to fit the needs of a specific shoot (see the real matrix for demonstration). We went with wood because it was cheap, fast to build, and readily available.

The radius we chose was roughly 5'. To draw the arc we took a 2x4 and drilled a hole in each end. Put sheets of plywood large enough to accommodate your rig down on the floor. In one end of the 2x4 put a pen and anchor the other end temporarily at the center point of the arc. Swing the arm around and draw a nice arc on the plywood (there are probably easier ways to do this involving wire or string). Once you have an arc drawn on the plywood get your cameras and space them evenly around the perimeter. Turn them on and see what it looks like. Put an object in the center of the cameras and adjust them so that they are all centered on the same object. Take a test shot on all the cameras. Make sure you are happy with the range of motion between frames and the proportions and position of the subject to the frame. This is one of the most important elements in getting a good shot in the end and it is one that is hard to adjust once you get the jig saw out, so get it right.

Initially, we made a smaller matrix rig, used velcro to mount the camera and had a session of shots to test the size and spacing. Afterward, we decided to expand the size of the matrix and created a larger platform and increased the spacing between the cameras.

Brilliant work!
DUDE! You look like the Fresh Prince of Bel Air!
Holy crap how much did this cost?!?
How did you do the light drawing 180?
Or you could just do it with 2 cameras, Photoshop and AfterEffects like they did here at the 1:32 mark: <a rel="nofollow" href="http://www.hadlowpro.com/">http://www.hadlowpro.com/</a>. They do it many more times in this video too. I know for a fact that they did it with only two cameras and some rotoscoping and morphing.<br/>
&nbsp;That video is SICK! did they just go frame by frame in photoshop? that would take forever.....
Safety tip, kids: Keep your fingers out of the path of the moving saw!
Aw, no fun...
This is definitely a great project, amazing results. While some of the costs may be out of reach for some you could still get interesting results if you used less cameras, it is still DIY. I made a few versions using 35mm film cameras photographing a whirling dervish, I hope to have time to post an instructable in july on my camera rig but until then you can see the results here: <a rel="nofollow" href="http://www.youtube.com/watch?v=KzL6fH-P0w8">http://www.youtube.com/watch?v=KzL6fH-P0w8</a><br/>
GRL is the dopest crew I have seen rolling other yet... my homeboy rolls with them and for whatever reason they need a laser cuter....... so I voted and you should too!!!!!!!!!!!!!!!!!
dopiest?
NOT A FAN OF RAP, BUT THATS A PRETTY SWEET RIG. BUT SEEMS LIKE A PRETTY STEEP PRICE TAG TO BE A "GHETTO RIG". LOW COST MAYBE, GHETTO, NOT BY A LONG SHOT. IMPRESSIVE TO SAY THE LEAST.
TYPE IN CAPS..........not good
Again congrats guys...
very nice work
I agree with a lot of you. This is not DYI. It actually looks professional, is too costly and is the same way done in the matrix. Nothing new, but i like the light effects around the guy.
Absolutely this is DIY. That's what you do when you don't want to drop \$100,000 to do it professionally... you "do it yourself"
I'm confused ;) When did "looking Professional" and cost take a project out of the definition and realm if DIY? Respectfully all the comments in this vein sound no different than the sour grapes overheard at any event, when someone is judged to be a winner

You could do bullet time if you used cameras that have the multi-shot option where they take multiple photos over a short period of time.
Um...24 \$300 cameras? That's a bit out of my league. And probably many others' leagues as well. That's like, what, \$7300? Plus \$150 for the light stands, and maybe \$500 for all the other pieces and tools? You could buy a car for that much! Not saying it's a bad 'ible, but...whew! Pricey!
im thinking of a different way of doing the same thing, but with one camera...
You could just record a video and have the camera roll on a track as suggested below or you could use a pulley system.
You could but the camera would have to move really fast to create a bullet time effect. Also the frame rate would have to be high.
Well, it'd still probably top off less than this.
That's true.
You could always try green/ blue screen
yeah, but i stuck with just taking pictures, the instructable will be up in a little while
Can't wait for the 'ible.<br/><em>I love italics in this font. I'm getting addicted! Help! 1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM</em><br/>
haha, i'll try to get it up after school tommrow
*June 2nd rolls around*
You know, this wasn't really bullet time. In bullet time, each camera fires within a fraction of a second of each other, so that the actor doesn't even have to slow down. That's how they do it in the Matrix. It has an easter egg in the DVD version that explains this when you select an image of the red pill somewhere in the menus.
wooo! now go to the place of a sun banks ;-)
mmm tasty
anyone got a spare small fortune so i can make one of these. my spare film crew needed something to do
The only thing ghetto about this is the film they shot. The way the built the system is the same as anybody with money would build this system. Same as the HP commercial they have been showing.
Anybody know of any interpolation software? ( Just to fill in the in between frames/pictures?) Thanks
CanÂ´t believe this won the 15k laser cutter! I know I havnÂ´t posted any instructables myself and therefore it might be conceived as arrogant of me to criticise this. But I am a fan of this site and I do think that its a site for and made by regular people. And in the spirit of ingenuity, outside-the-box-thinking and DIY it is my firm believe that giving the prize to this "instructable" is a slap in the face to the sites regular contributors. I mean, the bullet-time rig isnÂ´t really different to the ones used by (more) proffesional filmmakers - basically its a copy of the one used in the Matrix-series.....only difference being cheaper cameras, no blue (i.e. green) screen and less postproduction - but the setup of the cameras is nothing more than what anybody could learn from seeing the "making of" part of the Matrix dvds. And furthermore the cost of the materials used makes this instructable useless for most (if not all) of the sites regular users - really, how many guys and girls who spends their time building stuff out of garbage and old pc-equipment has a budget pushing 10k for building a bullet-time rig? The point being that this instructable isnÂ´t really that great - most people in here could have and probably would have built this if they had the budget. And I would argue that a lot of the cheaper projects in here would be far more obvious candidates for the first prize - certainly in terms of ingenuity and DIY-ness.... If a bullet-time rig was to be the winner, the prize should have gone to the guys from The Matrix :-) Best regards Kim
I agree
wowa! this is intense
Do they have to keep saying fuck and mother fucker? And, not to whine too much, but the beauty of the bullet time effect is that in the Matrix, they go from movement, to stoppage, to movement. I watched the whole video and didn't see one instance of movement/stoppage/movement.
just throw a video recorder at the end of the line of cameras
I somewhat agree, they did actually a chieve a very nice low budget bullet time RIG, but I am a little disappointed that it wasn't used to full advantage. Since I haven't done an instructable yet, I assume I'll get some attitude for making a negative comment... This is not to knock Grafitti Research Lab at all. I'm a big fan of their inventive projects and daring and all, but with that rig, I would just want to make some footage that really rocked our collective world. The effect as GRL used it in this film (the bullet time shots) I believe I could do a similar thing with one video camera and a handful of still images, and Adobe's sick new Creative Suite... and leave some money in the kitty for the wrap party's supplies. In fact, I guess I am just gonna have to see what I can do to put up an instructable about it,. All my comments notwithstanding, I think this was an excellent project, maybe not Grand Prize material, but really up there in the winning zone.
i agree and posted to the likes. i like what they did but can we say overkill.
i think it woulda been cheaper to just make a track and a high speed camera and just have to roll start to finish like how it was actually done. seems like a lot of extra stuff for how to do bullet time. its a great concept probably the easiest for the basic user to make, to do this effect and the most expensive. and i agree with russ nelson. thats not the matrix effect at all. i think this instructable is 100 percent over kill. ive seen a group called digital visions do this effect first hand a few times with a much simpler rig for the 420 outlaws. and i thought this guide would be along the same lines as there rig. and as i saw it my first and only remaining thought is. why would you do it with so many cameras. it worked but the question is not if it would work. its with that many cameras dang how couldnt you get that effect to work.
I've seen people made this 4 times... It was presented at a mall once. its pretty cool when they show the results. they charge 2 bucks though...
Wow.... you guys have done outdone urselves again! I friggin love it!
wow this sure is one of the best and most intense instructables ive ever seen
