well there are spin-rigs on which you can mount cameras, The SloMoGuys had an opportunity to try a few different things with one in their super slow show. The problem with spin rigs that this setup solves is one of speed: I don't know the upper limit on the potential speed of rotation for a 7.7 kilo camera (v2511 w/o lens) at the end of a 4m arm, but it can't be super high because the sheer weight of the camera was making the whole thing a bit wobbly (yes I know that with a stronger arm and a better counterweight system they could have gotten better results). On the other hand, the spin rigs only require one camera. Granted, it's a faster camera, but one camera vs the nearly 50 in this setup seems a bit more cost-effective

Absolutely brilliant.

9.4km/s !!! LOL Its hard to imagine how much hours of work you and your team put in building that Ring, but the ending result is absolutely insane! Keep the amazing work.

This is amazing. Your always pulling off some pretty incredible things, nice work.

If you play two copies of the same video side by side, but one lagging behind a few frames you can get cool stereoscopic video for cross-eye viewing. EDIT. I tried opening this video twice and it works. Angle differences between shots are very large so 1 frame of difference between images is more than enough.

Should use some optical flow to interpolate between the cameras, especially since as you have such a large frame rate at each position, should interpolate quite well.

We can juuuuuust fit 96 cameras in portrait mode, if we flip the ring portion of the truss upside down and mount the cameras on the largest diameter portion. For a lot of shots, portrait is actually the most appropriate anyways.

I love this! Ideas for future uses for this?? Perhaps making some kind of half-sphere array of like 200 or so cameras! That would be so cool but the data coming off that would be crazy! But to be able to choose any angle of a given high-speed shot... that would be something else!! It would require a crazy type of truss system to be able to hold it all, of course. But the possibilities of getting shots from 180-degree half-sphere of cameras... that would be amazing!

Fewer cameras can be blended via a photosynth process to create a 4D point cloud and allow visualization of dynamic events from arbitrary viewpoints.

Wow - this is a game changer! I bet you will pull in some orders just because of the versatility.

For all of the comments that mention motion sickness due to the constant rotation, rest assured that with software interpolation you can slow it down and alter the look. You can also slow it down easily by repeating frames. This is an amazing rig that should provide many scientific, industrial and commercial imagery breakthroughs.

Thought, could a perspective program be used to piece together a seemingly still image, like a go-pro 360? I know one would loose something in the process...

To a extent yes, but you can't do 360 degree stills, there has to be a minimum amount of motion. Whereas if you capture all angles at once, you can freeze action and show it from all angles.

Awesome concept and implementation. Great projects can be made with this rig. But also agree - spin speed around the object should be at least 3x slower. Or probably slow where the impact is and fast until it gets to other impact point. Exceptional work.

Is there a way you could use this to create a virtual reality image that someone could walk around and see every angle?

Ooh! Ooh! Just had visions of 3d photogrammetry and creating particle simulations from the data using this technology. 😮

Mesmerising stuff! I had to keep reminding myself it was my perspective rotating and not the object. Some description of the subjects would have been nice though.

Guys a great set up of very expensive kit. You need to have the circular trusts be motorised so it can move from top to bottom super fast (just like when they shoot with a robot arm slo motion shots) having this set up with motorised camera up and down mounts will definitely create a very special perspective. Constructive Idea! For now the spinning effect starts to have a motion sickness effect. I understand your setting up but for present setup post editing would be great to keyframe to best framing perspective of the subject at many parts of the timeline. Would love to be part of this!

this is amazing :O

Doubling the number of cameras (as crazy as that would be) would also mean 4 seconds per rotation versus the current 2 seconds. Except for events at the center of rotation, it was a bit hard to follow the action due to the fast spinning (and my stomach/inner ear didn't like it much either.) But an amazing thing to get working and it was very cool to see those events unfold in moving slow-mo like that! Well done!

It would be interesting to try using the NVIDIA's Super SloMo to generate intermediate frames to slow down the rotation to be a full revolution every 4 seconds instead of every 2 seconds. How are they synced? Can normal cameras be synced like this? Like say 192 sony rx0s and using them at 240fps get 46000fps footage at 1080p?
