How is this guy filming this?

A buddy that skates as well as him? This confuses me. There was a time that I played with the inline skates. This guy's insane but I appreciate him risking his life to get these videos.

I think the "360 [degrees] camera" he's using means something like what the "backup" (actually all-round) cameras of expensive cars are nowadays: Cameras filming all around him, combining that for the surroundings, panning (in software) to a different perspective in front of or behind where he actually is, then interpolating his body (harder to do that with a car body, not sure on this) into the end result. That's why he isn't shaky at all, as he'd be if he were filmed by someone else: The filming is done from his point of view. N.B: He isn't shaky, but there are some shimmering edges to his legs (e.g, around 1:40). Image processing artifacts from putting him into the environment, and processing the top-down view of him into a frontal one, would be my guess. TL,DR: I think he's filming himself, from on top of his head. ETA: Not as much of a hotshot as he likes to make himself look on film. Did he bump into that motorbike at ~5:55? Clearly a bit edited out. -- Christian R.

I'll accept the selfie stick that has been edited out. But sometimes there are far away views. That's a goddamn long selfie stick.

They only use a pre-built 3-D model of themselves; possibly with slight variations for doors open etc. And I suppose if you have it re-sprayed in another colour it'll still show the factory-original hue on-screen. Check any (semi-)recent video of a Mercedes S-class,BMW 7-series, etc by Doug DeMuro or some other such car YouTuber. Yeah, no way was I suggesting he had that kind of processing power on top of his helmet. If it were done that way (seems less likely now that people are pointing out the selfie stick), it would have to be post-processing. But this was no super-amateur video; I assumed all more or less professional YouTubers do quite a lot of that. -- Christian R.

Post #443,510 by CRConrad 10/5/23 2:31:26 AM 10/5/23 2:31:26 AM Reply	Yeah, but off-the-shelf for luxury cars now will be... ...off-the-shelf for YouTuber hat-cams in what, three-four years? I saw this review of, think it was an S-class, where DeMuro (or whoever) fiddled around while standing still: Pinch-to-zoom, swipe to pan, etc etc, on the touchscreen, and he got a made-up perspective from some point of view where he wasn't and no cameras were. "OK, let's fly up and look down on ourselves", like. Can't recall if he demonstrated or just said that "On the freeway, we can 'drive behind ourselves and look at ourselves from the rear' -- or from in front or any side." In that courtyard demo, it was as if the camera was on a drone, buzzing around the car. OK, so I was apparently (or at least most likely) wrong in thinking that had trickled down to YouTubers' hat-cameras already, but for all I can see, it will. Soon. (Wow, isn't the IT industry great? We're really contributing to making the world a better place! Soon narcissistic exhibitionists in rich countries won't have to schlep around selfie-sticks any more! What, me cynical?!?

The selfie-stick footage shows faces and bodies in real time. There's no software yet doing real time generation of human movement. -- Drew
Post #443,520 by CRConrad 10/6/23 6:08:44 AM 10/6/23 6:08:44 AM Reply	Yeah, I forgot his face. Changing perspective on the movement of limbs seen from on top of someone's head into seeing them from in front or behind is a big enough ask, but I suppose it can be done... But from up there, the camera doesn't see his face at all. Duh! -- Christian R.

Post #443,524 by crazy 10/6/23 1:55:54 PM 10/6/23 1:57:35 PM Reply	A simple helmet mirror would do it Stick it out on an arm like a bike mirror except have it within the camera's view to get the face and body. Four of them with four cameras (or two of them with really wide angle but that would add to the computer stitching so I would use as many cameras and mirrors as possible) and you can get mostly everything. Software should be able to do the rest but that's got to be some serious compute power and algorithmic brilliance as it joins it all together, reverses for front camera, looking back at your face viewpoint, combined with flipping all the traffic and joining it with the other camera viewpoints in the non-body portion and upside down flipping your body and stitching it all together. Hey Drook, it's a gleam in my eye. Nah, that's the glassiness from smoking pot. It's a pipe dream. But someone else could do it. I don't actually do anything anymore, I'm more of an idea rat.

When it looked like something good was happening, they'd hit the button and they'd all fire at once. Then they could rotate the view and see it from all angles. I immediately imagined putting 4-8 cameras - video, not still - around the court and use software to simulate intermediate views. Picture they can spin a dial to select a location for a virtual camera. -- Drew

Only hardware does, (barely) compensating for software getting slower. -- Christian R.
