Destin from SmarterEveryDay has posted an incredible video explaining how a lawn mower cuts grass. It is way more interesting and memorable than you might think. The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even. The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera.

NVIDIA has been hard at work on the problem posed by high frame rate interpolation of video data shot on lower fps. We have had this tech since the late 1990s with the advent of Twixtor and refined over the decades in systems like Twixtor Pro and Adobe’s Optical Flow in After Effects. You are still not getting real temporal detail data since the frames are created by extrapolating velocity and direction vectors plus pixel values between frames to get the result.
We explored this technique in our post on interpolation here and why it is no substitute from a real slow motion camera solution. NVIDIA’s new method uses machine learning along with 11,000 videos to arrive at a more convincing result. Considering the relatively small sample size we can imagine a future where hundreds of thousands or millions of footage samples are used to generate near flawless interpolation. This technique takes some serious computation and data sets so as of now it is not really ready for the mass market but that could change with the cloud very soon.
The fps1000, fps2000 and fps4000 projects are alive and well and are progressing forward with a unified hardware base. We are not able to share information the current state of the project other than it is advancing to a ready to ship point in the future to all outstanding backers. The fps4000 camera is able to be rented now in the United Kingdom at this website for £150.00 pounds a day plus VAT & Insurance.
We are awaiting a 4k version of this camera in the future and the current fps4000 looks to be evolving to include a Sony Infolithium standard battery which also looks like a grip of sorts. You are able to rent it with a micro 4/3 mount or a Canon EF if needed. Some may point out that if its available for rent it should be ready to ship but these cameras are engineering non-mass production samples that are still evolving. The rental house also helps the project by testing and finding issues with the camera with the help of production users, that can be corrected before final production.
The fps4000 is starting production of 1080p units with 4k cameras following closely behind. The Slow Motion Camera Company Ltd. has launched a new website today with specs, pricing and an easy order page which will let you finally be in the order queue for an fps1000, fps2000 and fps4000 camera.

We are expecting an fps4000 camera for our lab sometime in the 1st quarter of the year which will let us put it through its paces. The cameras aim to change the way you record slow-motion footage by allowing up to 2 minutes continuous recording in camera solid state memory which can free up DPs from the typical few seconds in slow motion cameras. This, in theory, allows recording an entire production in slow motion which can be ramped in speed slow or faster if needed.
The fps4000 camera hinted in Q4 of 2017 as the camera to replace the fps lineup is now entering its first production batch and it will fulfill the promises to backers that expected a camera either in 1080p or 4k. The fps4000 will reach up to 4k resolution at 500fps in it’s highest configuration. This is half the performance of the Phantom Flex 4k camera when it comes to frame-rate at that resolution.
The fps4000 also has a lower resolution configuration for 1080p at 2000fps. Back in 2017 on the announcement, there were configurations up to 4000fps at 720p using different sensors. The hardware main design seems to be shared among the cameras which makes it possible to offer different models at accommodative costs. This should allow all Kickstarter backers to have their promised camera and continue the line for new customers who need low cost extra long recording times in camera.
