Came up on my feed a few days ago. Looks like convincing ball lightning to me: https://youtu.be/mmOfwFHBu_o
It's likely an arcing powerline (see the reddit comments):

Correct me if I'm wrong but looking at the video this just looks like a 3D point cloud using equal-sized "gaussians" (soft spheres) for each pixel, that's why it looks still pixelated especially at the edges. Even when it's low resolution the real gaussian splatting artifacts look different with spikes an soft blobs at the lower resolution parts.
So this is not really doing the same as a real gaussian splatting of combining different sized view-dependent elliptic gaussians splats to reconstruct the scene and also this doesn't seem to reproduce the radiance field as the real gaussian splatting does.

I want to play something on my keyboard (the only instrument I am slightly ok at) and then be able to tell it to play it with a saxophone and describe exactly how I want it played. I don’t need an AI to create a song for me, I need 100 session musicians at my disposal to create the song I want. I am very excited about having that type of ai.
Here is a cool demonstration to do voice-to-instrument or instrument-to-another instrument
(The inconvenient thing is that for a new kind of output sound you have to train a model for around 1 hour for good quality, but after that you can use it with different inputs quickly):

Edit: nevermind, they are in fact affiliated, and most of the core VLC devs work at VideoLabs. I've kept the original comment below.
This blog post links to the "VideoLab Store", hosted at https://videolabs.io, which prominently uses a logo extremely similar but not identical to the VLC (which stands for VideoLAN, not VideoLab) logo. Their homepage even goes as far as displaying "Hire the VLC team" as its headline.
As far as I'm aware, VideoLab has nothing to do with the VideoLAN non-profit, and it very much seems like they are intentionally trying to mislead people into thinking that they are the developers of VLC.
From their about page:
Videolabs was born from the VideoLAN community and started by maintaining the VLC ports on mobile. It is now the main contributor to VLC, hiring its historical developers, and building custom solutions around the VLC and FFmpeg ecosystems.

ClearMotion founder here! Wanted to share some insights that might answer questions from other commenters and clarify what we've developed.
The ClearMotion1 system is a major leap above all tech currently on the market, with transmitted vibration reduced about 80% versus top market technologies. Here's a video comparing it on production NIO cars against luxury vehicles using semi-active (or slow active) systems others mentioned - sort of like comparing a microcontroller to a NVIDIA H100. http://bit.ly/44TDtgl
This matters especially for autonomous vehicles, where the whole point is to give people back time, and preventing motion sickness while working/reading is essential.
Our tech stack:
- Electro-hydraulic actuators that both push/pull actuate and dampen within a few milliseconds, using electric motors (not solenoid valves or special fluids). We use integrated hydraulics as a mechanical gain lever
- Predictive control software that anticipates vehicle, driver, and road dynamics
- "Infinite preview" control using crowdsourced road data with <3cm localization precision
- Software-enabled features including pre-crash posture mitigation and tire grip technology
The combination creates a "software-defined" chassis, similar to how electric power steering enabled today's driver assist features.
Our Bose acquisition was to acquire specific control software and engineering talent, but most of our IP and our production hardware/software was developed in house.
There were a few questions about durability— our system has passed 5 years of testing across millions of miles - a requirement from all of our customers like NIO and Porsche. It’s also a reason why it’s so difficult to succeed as a startup in automotive, but once you’re in, you’re locked in long-term.
The article says that Bose gave up and sold the rights because:
"Sadly it was totally impractical for mass production in 2004"
What does that mean? Was it too complex or costly to make it back then? Did that change now with your developments?
Better tech is nice but if it's to expensive or hard to mass produce then it could end up the same way as with Bose.
There is also KaraKeep:

Seems very similar.

When you zoom in on the cracks, you can see the bevel on the edge of the crack. That’s incredible.
In many places on the edges of the cracks in the dark background you can see tinges of blue or pink color. Is that from the lighting, or is the color actually there, if it is there, anyone have an idea why?
Also at many places the cracks seems to be overpainted, filled in. I guess that's from the restorations...
I just looked it up and there is a picture from an analysis where they are showing its possible state before the restoration:

"In UV fluorescence, the natural resin varnish layer fluoresces greenish, and areas retouched in 1994 can be distinguished from the original paint as they appear darker"

and the next step is a monthly subscription fee to use your camera...

I am not really technical in this domain, but why is everything text-to-X?
Wouldn't it be possible to draw a rough sketch of a terrain, drop a picture of the character, draw a 3D spline for the walk path, while having a traditional keyframe style editor, and give certain points some keyframe actions (like character A turns on his flashlight at frame 60) - in short, something that allows minute creative control just like current tools do?
Huh "everything text-to-X"? Most video gen AI has image-to-video option too either as a start or end frame or just as a reference for subjects and environment to include in the video. Some of them even has video-to-video options too, to restyle the visuals or reuse motions from the reference video.
Yea, I know that was the case when I clicked on the thumbnails and couldn't close the image and had to reload the whole page. Good thing that you could just ask AI to fix this, but the bad thing is that you assumed it would produce fully working code in one shot and didn't test it properly.
