Samsung ISOCELL GN2 does 480fps!

The hegemony of phone sensors has been the purview of Sony with their Exmor sensors for many years but now Samsung has started making inroads in the space with their ISOCELL chips. The latest is currently mass-produced and shipping in handsets already which is not a paper launch, but a real thing. The chip is capable of massive low light improvement compared to other sensors because it is essentially a near 1″ sensor with 1/1.12-inch measurements. This is close to what Sony RX cameras use as a main sensor, and a first for a phone.

As to how they are able to fit this sensor on phones, it is a dance between a protruding camera bump that is a little larger than usual and also a lens system that creates a full imaging circle from a minute distance. The GN2 is capable of recording 480fps in HD 720p, 4k 120fps, 30fps in 12.5MP windowed size and 10fps in 100MP mode which uses a clever algorithm and three RGB exposures to derive a 100MP image from the 50MP source. → Continue Reading Full Post ←

Sony a7s III Slow Motion Samples!

Sony a7s III Slow Motion Samples

Now that the excellent a7s Mark III video recording mirrorless camera has been out for over six months, it is time to revisit the slow motion component and see what quality we can expect from the Sony a7s III Slow Motion Samples. Many have praised the 4k 120fps mode which is heavily detailed, low noise and suffers from only a very small crop factor that is hardly a problem.

We looked at the Full HD 1080p 240fps mode on the camera and it was clear it did not match the 120fps 4k mode as it was not only less detailed but full of aliasing and moire if you looked for it. It was clear the camera was not up to professional standards when in this mode which is to be expected from a full-frame sensor cropping to 1080p. That said, this camera is a powerhouse that easily takes the mantle as Sony’s best mirrorless compact video camera.

Sony a7s III Slow Motion Samples:

Be aware that 120fps in 4k is not only highly detailed and full of dynamic range but it is the best high frame rate this camera has to offer. You can easily use this mode for professional broadcast or film work is shot in good conditions.  The a7s Mark III is the best Sony Alpha line camera for low light performance and it is evident by the samples this translates directly into higher frame rates.

Sony A1 Slow Motion has 8x Mode!

Sony A1 Slow Motion

Just in time for the Japanese Olympics if they ever take place, Sony has released the Sony Alpha 1 or A1 for short which is probably the most powerful mirrorless camera ever produced.  Customary for Japanese camera manufacturers in Olimpic years, the likes of Canon and Nikon have released their professional flagship products like the  1DX and D6 which are still SLR mirrored products that have the highest possible Autofocus features for a camera of that type as well as speed and dependability.

Sony has had some inroads in that space with the Sony a9 series but they were missing a higher megapixel count version that could really differentiate it from the pack and the A1 seems to be just that kind of product. By shooting 8k video at 24,25 and 30p it becomes future-proof for the next decade as far as resolution goes and by taking 30 images per second in stills mode at the full 50MP resolution with AF Tracking, it is one blinding fast beast.  The fact that it also shoots 120fps 4k and 240fps Full HD doesn’t hurt it either.

The Sony A1 is probably the fastest mass production professional hybrid camera ever made. The speed required for 50 megapixels at 30fps means that it is processing and saving in RAW format or RAW+JPG to CF Express Cards  at 1.5 Billion Pixels/Second and all of this while using the 120Hz continuous intelligent Auto Focus for people and animals.

Sony A1 Slow Motion Frame Rates:

  • H.264/XAVC S 4:2:2 10-Bit

  • 50p/59.94p/

  • 8x Slow motion is 240fps played in a 30fps timeline!

The Slow motion frame rates are also here with up to 4x 120fps in 4k 10 bit at up to 280Mbits/sec and 100 to 240fps 8x in Full HD 1080p at 50Mbps.   We can see the sample below that contains several clips at 4k 120fps and some intercut 240fps Full HD like the divers shot in Hunters Of Light below.  We can safely say that the quality at 4k 120fps 10 bit is near perfect but we still cannot attest to the quality of a file in Full HD at 100, 120, 200 and 240fps derived from a Full Frame sensor recording from a 50MP source.

We have confirmed that the camera has a 21 Megapixel crop factor in APS-C size for stills and possibly video which probably means that all the higher 1080p frame rates are possibly extracted from the crop area of the sensor and not from the full 50MP area.

Cheapest slow motion camera for $6 does 660fps!

Cheapest slow motion camera

We just received a video link for a Raspberry Pi imaging platform that allows for 660fps slow motion video capture using the computing unit along with it’s memory and a $6 USD camera to record slow motion video with better than expected results. The video from 2019 by RobertElderSoftware explains the way the camera and R-Pi were able to capture the footage using some scripting and writing a windowed wide but not tall imaging rectangle directly to memory to create the cheapest slow motion camera.

Of note is the apparent low resolution of less than VGA at 640 x 64px and the somewhat appraisal of rolling shutter artifacts on some of the coins. However, RobertElderSoftware also has a step by step instruction video set on how to get a $40 Raspberry Pi computer and a  $6 USD camera module to build your own homebrew slow motion camera with some scripting.  After a lot of scripting and patience, you should be able to mimic his results.

Cheapest slow motion camera using a Pi Unit:

It is literally amazing what a dedicated engineer with an extremely limited set of tools and cameras is able to do on a project like this. Now imagine RobertElderSoftware using something like a more powerful ARM-based Mac M1 or similar with way more RAM disk for capture along with a better camera and sensor combination.

You can visit and subscribe to Robert Elder’s Channel here and learn many more from his cool projects and coding guides!

Maybe in the future, we could see some homebrew project kit that could be able to shoot 500fps or even 1000fps in 4k for a limited investment. In any case, we feel that you should take a look at the project below and get inspired.  We thank our reader Nacho Simon for the heads up on this awesome project and Mr. Elder for his creativity and drive! -HSC

Chronos 2.1 HD Slow Motion Camera use is exploding!

The Chronos 2.1 HD Slow Motion Camera which is the larger sensor and resolution version of the Chronos 1.4c is now being used in a lot of production situations. The material created with it gets better and better and while there is still a small backlog of camera orders due to COVID 19 disrupting part supply channels, most orders are now just a few weeks behind.

We have looked at a dozen videos that we would like to share with our readership showing the Chronos 2.1 HD in full force shooting in exquisite 1080p quality.  We are still waiting for a review unit which was delayed for a shortage of components to get to us but needless to say, the camera is gaining a very good reputation as the lowest price vs. quality option in the 1000fps 1080p camera world.

Chronos 2.1 HD Slow Motion Camera Video Samples:

We have seen a plethora of footage shot with the Chronos 2.1 HD lately which shows how Krontech has been able to ship a boatload of cameras across the globe.  You will find professionals and hobbyists alike shooting incredible material with the camera which is probably the best looking 1080p slow motion footage under $10,000 we have ever seen.  This little camera is making inroads into the market that is probably causing headaches to the higher end high-speed camera manufacturers. We can’t wait for Krontech to use what they have learned here to go even higher and offer a possible 1080p 4000+fps camera or a 1000fps 4k camera in the future.  Congratulations to our Canadian friends!

Phantom Slow Motion Camera Used to Study Coughing Reach!

Phantom Slow Motion Camera

Schlieren Imaging has always been a very narrow and specialized field of imaging. It can visualize air perturbations in a fluid-like way that can show the reach in this case of someone’s breath and heat dissipation to see if a mask makes a large enough difference in transmission of infected airborne particles compared to no covering.

By using a Phantom VEO4k 990 slow motion camera at 938fps and a speckled background with specialized angled lighting, researchers were able to test a variety of masks while coughing to see the effects.  You can watch the video posted here and also check out the full study available here if you want to dig deeper. → Continue Reading Full Post ←
