Chronos Camera m43 Lens Adapter with Speedbooster Support!

The two existing Chronos cameras, the 1.4c 720p at 1502fps & the Chronos 2.1 -HD 1t 1080p 1000fps are identical when seen from the outside but very different inside as they contain different sensor and memory boards. However one constant is that both use the C mount as the default for lens adapters. The camera usually comes with a Canon EF or Nikon F mount adapter depending on the buyer preference which screws on the C mount thread and allows for support of classic lenses from Macro to telephoto. 

One request from the community has been the support for other lens mounts like Micro 4/3ds which lets you adapt a variety of lens mounts and the much coveted speedbooster adapters which allow a 1 f-stop improvement in light gathering for micro 4/3ds systems. Today Krontech, the company behind the Chronos high-speed camera is introducing a passive Micro 4/3rds adapter for both the Chronos 1.4c and 2.1-HD and uses the body screw terminals near the lens thread mount to place a solid connection that allows such lenses. → Continue Reading Full Post ←

Multiply Your Video Frame Rate with Dain-App !

Multiply Your Video Frame Rate

We got over 20 messages with essentially the same video sample in our inbox this week. They all touted the new interpolation from the DAIN experimental App or (Depth Aware Video Interpolation App)  which now analyses footage with a Neural network AI algorithm that crunches motion vectors and even what seemed impossible before “Object Occlusion” to generate higher frame rates from lower fps sources.  The technology is pretty fascinating and should be further improved by more training and samples over the coming years.

For stop motion animators, this is a complete game-changer as now you could animate with as little as 8fps and then interpolate to 30fps or 60fps with very little in the way of tearing and artifacting as long as the footage is well lit and objects clearly defined.  To make matters more interesting, it also analyses footage with shallow depth of field yielding impressive results.

Multiply Your Video Frame Rate with Interpolation or the “I” Word for Slow Motion Enthusiasts:

We visited the Interpolation topic in the past on our Fake Slow Motion article and concluded that then, the quality of interpolation while good was far from usable and you really could not compromise real high fps footage from interpolated versions except in very simple cases.

Now with DAIN technology, we have no choice but to re-visit the cases and analyze what it is capable of.  We looked at a few dozen examples and it is clear the technology has progressed forward so much that now stop motion animation, 2D Cell-based cartoon animation, and even 3D animated sequences rendered at 30p can easily be turned in higher fps increments yielding impressive and in some cases miraculous results.

We would like you to first watch the video below to understand what a depth map is and how the software in DAIN can create frames from nothing that look just like real ones.  A depth map will generate an approximated view of the world in a Lidar-Like vision representation to figure out to the best of the AI estimation where objects are in a scene according to their location close or far to the camera.

Depth-Aware Video Frame Interpolation by Wenbo Bao:

Even at 48fps from  12fps source, it is clear the technology in DAIN can yield impressive results even with heavy organic detail in the background including foliage. The software does an admirable job of estimating the relative position of objects in the video scenes.

Krontech Releases Chronos Software 0.4 with LAN support!

Chronos Software 0.4

Krontech.ca the makers of the Chronos affordable professional high speed camera have released the Software version 0.4.0 Beta of the camera platform.  The cameras will now be using an embedded build of the Debian operating system which was already the default OS for the Chronos 2.1 HD.  All Chronos 1.4c cameras can now be upgraded to the new Beta version free of charge Follow this link for the official thread.

We tested the software briefly and found it to be responsive and solid.  However as a Beta, you should be ready to find some glitches here and there, if you are doing mission-critical work you should wait for a full release before updating to be on the safe side, we recommend it for most users who are not shooting once in a lifetime events. If you do find bugs please contact them to help squash them out.

Chronos Software 0.4.0 Software Beta:

Official thread, installation instructions and download link here!

Notable Changes:
– Support for the LUX2100 image sensor.
– API for camera control via JSON/HTTP over the Ethernet port.
* Examples: https://github.com/krontech/chronos-examples
– Saving of media over network to an NFS and Samba share.
– Software updates can be downloaded over the internet.
– Real-time video stream from the camera using RTSP.
– New back-of-camera GUI is available via the software update screen.
* For more information: http://forum.krontech.ca/index.php?topic=498

The biggest change is the ability to control the camera via Ethernet which gets it into more professional settings that allow for a really long tethering solution or using a small portable LAN Wifi router like the ZyXel here which will allow wireless control from afar. As of now it allows the use of control scripts that will operate the camera remotely with a great deal of customizability.  For situations that require the camera to be sealed and controlled remotely and unattended, this is an ideal solution. We will revisit the feature once we have tested it.

Spice Slow motion test chronos camera 2.1 HD by LaSt Studio:

We love the new Dark GUI and we especially find it comforting to get more video preview space which was taken by the old interface scroll bar and buttons. Now the video preview takes center stage much like what you see in other professional cameras like the ones from RED and or Blackmagic design.   We will test the new software in our next shoot with the Chronos 1.4 and will get a 2.1 HD to review later this year. Stay tuned!

Chronos does space science:

Krontech also shared this article in IEEE Spectrum magazine that details the work by Masten Space Systems on creating instant landing pads for future space exploration vehicles. The technology uses the rocket exhaust and composite materials to create a kind of lilypad array on planetary surfaces to create a stable base for exploration modules.

The Chronos cameras were used extensively for testing the different materials and exhaust plumes of rockets on their research. The footage below shows part of the Chronos camera imagery analyzing different test cases of the technology. We estimate the Chronos 1.4c was used for this project.

It is exciting to see Krontech catering to many labs now and creating a name for itself in the Aerospace industry by showing affordability does not necessarily mean unprofessional.  The fact that rocket scientists are using the cameras with great success should make it an easy purchase for many other labs.

Sony FX9 Slow Motion is Good But Not Great!

Sony FX9 Slow Motion

The new Sony PXW-FX9 XDCAM 6K Full-Frame Camera is what Sony fans have been waiting ever since the APS-C cameras Super 35 cameras like the FS5 and FS7 made the rounds. It is all that those cameras offered but now on a state of the art Full Frame sensor with Dual ISO capable of 800 and 4000 depending on the needed use. By being extremely sensitive the camera needs ND filtration and it doesn’t disappoint on that feature either by including a ramping – smooth increments ND filter from 1/4 to 1/128 which adjusts on Auto Mode depending on the scene without ruining the shot. An industry first.

On the Slow Motion front, the camera is consistent with Sony pedigree with now offering 120fps Full HD and with a promised firmware update 180fps Full HD and also 16-bit raw 4K/2K footage up to 120 fps to an external recorder.  This is close but not quite what the FS5 is capable of in FHD which includes 240fps. The FS7 has in contrast 240fps @ 2K RAW Ext Rec & 180fps 1920*1080 Internal. Much closer to what the FX9 is capable of doing.

Sony FX9 Main Specs:

  • 6K Full-Frame Exmor R CMOS Sensor
  • 15 Stops of Dynamic Range
  • UHD 4K (3840 x 2160) up to 59.94p
  • HD Recording up to 120 fps & 180fps with Firmware Upgrade
  • 120fps 4k RAW 16 bit External Recording (Future Firmware)
  • 10-bit 4:2:2 to dual XQD media card slots
  •  561-point phase-detection AF sensor
  • ISO of 800/4000
  • Auto ND Filter 1/4 to 1/128
  •  XAVC-I with 422 10-bit quality
  • Built-in gyro For Metadata Post Stabilization. No IBIS!
  • 4-channel audio recording
  • 12G-SDI and an HDMI for 4K output
  • 28-second Cache Recording to prevent missing any shot!

https://www.youtube.com/watch?v=JO625L0qxGo

Slow Motion Specs of the FX9:

  • 4k 50p/60p
  • 4k 100/120fps RAW 16 Bit Firmware External Recorder
  • 120fps Full HD at launch
  • 180fps Full HD after Future Firmware Upgrade

The camera includes a “Quality priority setting that maximizes Full HD slow-motion image quality with advanced oversampling technology.” As to how good the camera will be able to preserve full HD quality at up to 180fps remains to be seen but it is encouraging to see that they are serious about the image quality in these modes. If Sony is able to deliver identical quality at 120 and 180fps as the regular supersampled Full HD we will be impressed.

The Slow Motion component of the FX9 is a good compromise when we see that it sports such a large sensor that needs to be great at several ISOs from lows to highs.  The rolling shutter might be larger than other S35 cameras but you are also able to record in crop 4k S35 mode. So it really is an FS7 II camera with an impressive Full Frame Sensor, usable Autofocus and the world’s first variable ND filter with Auto mode.

The letdown here is the no mention of the Sony 240, 480fps and 960fps Super Slow Motion HFR modes that were in the FS7 as options. Sure there were not ready for full production quality since the information was lost but this is apparently a compromise from the full-frame sensor unable to scan at such high frame rates. For serious users of this camera this should not even be a problem, image quality in regular modes trumps gimmicky high frame rates. So the HFR mode is gone here and we hope not for ever on Sony Pro video cameras.  We can excuse it due to the state of the art Full Frame sensor.

Destined Evolution:

The FX9 is the culmination of the evolution of the DSLR revolution started by the Canon EOS 5D Mark II which introduced the Full Frame look to digital video. However, this camera is so much better in all respects that it is kind of a bad comparison. No Aliasing or moire artifacts in 4k supersampled mode, better frame rates, better color science, better codec and features unique like the ND and AF with face detection.  If Sony can translate a lot of this technology to the long-awaited Sony a7s III if it ever ships, will be really mind-blowing.

Maybe the best part about the FX9 announcement is that the Sony FS7 & FS7 II will be lowered in price due to the displacement made by the new camera. The FS7 is an incredible performer that is production tested with very good slow motion performance.

We will have Sony FX9 slow motion clips as the become available. Since the firmware is pre-production we will not be able to judge any clips until the final release to avoid making an uneducated guess for the final quality.  In the meantime look at the videos below about the camera which will educate you really well on the capabilities and quality, you can expect.  Thanks for reading -HSC

Slow Motion News August 2019

Slow Motion News

We have a few developments to share in the high speed camera world. Things have been somewhat quiet in the phone front as the high speed component feature was relegated to a footnote in 2019 after a great 2017 and 2018 main spec treatment. We may get much better phone slow motion as memory size and speed increases while maintaining the same price range thanks to the fast pace of electronics development.

Sony just announced their latest RX VII camera which means that an RX10 and maybe a new RX VA version will show up before the year is over.  We were not happy with the feature being stagnant in resolution and speed on the RX series for 3 years in a row now. Sure AF and overall speed have increased when it comes to other parts of the camera but the high frame rates remain frozen in 2016 specs.  In the meantime, we have a few new things to show you.

Chronos 1.4c Camera Software V0.3.2 Development improves Frame Rates and adds new features:

We installed the Chronos V0.3.2 RC1 Beta software and on initial testing find the software to be mostly stable and the new features make it a better camera all-around.

In our testing, we found that noise and column gain was reduced considerably after a 15min warm-up.  Also, the saving to SDHC cards is faster in RAW mode, we were getting 4.8fps instead of 3.7fps in 0.3.1 this makes a very noticeable difference in saving speed which seemed too restrictive in RAW.

We did encounter some problems when using HDMI external monitors and viewfinders when using the peaking function. These are already being patched for the next release so we recommend you wait for v0.3.2 RC2 if that feature is needed while monitoring.

The camera now has the ability to format and see how much space is left on SD and USB/SATA media which is a very welcome feature set for on the field users. We would love the ability to load saved clips for playback at a later date as software evolves including post save editing and clip erase if possible.

Another welcome feature is now the ability to shoot even faster frame rates for all resolutions. 720p has gained 17 frames from 1502fps to 1519fps which is our main use resolution.  However, the camera is now able to shoot up to 40,420fps at 320*96 pixels which used to be 38,565 fps for a 1,855fps gain with no quality degradation. It is not often that you get free speed in any camera, this time it is lossless and operates just as before.

For more information on the Chronos 1.4 camera visit the Krontech.ca and or info on the patch at the development forum thread here: http://forum.krontech.ca/index.php?topic=488.0

Notable Changes:
– Automatic ADC calibration during black calibration, which should reduce column banding across a wider temperature range.
– Add a storage tab to the util menu to view, eject and format the attached storage devices.
– Speed boost at most resolutions, with a top speed of 1069fps at 1280×1024, and 40420fps at 320×96.
– Configurable automated power-on and off depending on the AC adaptor status.
– Option to disable the ring buffer when in segmented recording mode.

Minutae:
– Factory black calibration is now user accessible from the Factory tab of the util window.
– The software update button has been moved to the storage tab of the util window.
– Shipping mode to disable power-on by battery until an AC adaptor is attached.
– Add a watchdog to reboot the camera in case of a power-on boot failure.
– Display descriptive error strings instead of number on failure.

Fixed Bugs:
– Gated burst record mode may lock up after several trigger edges.
– Gated burst record mode unreliable when trigger debounce is enabled
– Memory leak in the M3 video coprocessors which could lead to a crash after lots of H.264 encoding.
– Ignore video which was recorded during zero-time black calibration (which happens after changing resolution).
– Stuttering issue on the playback window on new production LCD modules.
– Fixed deadlock in camera when restoring user settings from external media.

Fixed since V0.3.2-beta-6:
– Changes to focus aid or exposure aid (zebra stripes) would have no effect until resolution is changed.
– Changes to exposure may be overwritten during black calibration.
– Bad image quality at 336×120 resolution
– Util window, storage tab – bottom of text cut off if device has multiple partitions
– Factory black cal (black cal all resolutions) would get overridden by old user black cal, if a user had done their own black cal, even before.

Known Issues:
– On the save file settings window, the bitrate as listed above the resolution may be lower than the actual bitrate, if Saved File Framerate is lower than 60fps

Xiaomi Black Shark 2 Pro Phone Announced with 1920fps at 720p!

https://www.youtube.com/watch?v=MMlgedBJo3g

As we have seen from Chinese phones this year, the 1920fps spec for slow motion at 720p is included in several spec sheets like the Nubia Red Magic 3 but we found out that it is not only a fake spec but the actual video quality is pretty low.  The phone uses a 480fps capture at 720p and then creates interpolation of 4x  which is 480 x 4 =1920fps to create the final video. In some phones, it is just playing back 4x slower but in others there is interpolation. WHatever the came may-be, you are better off by avoiding this feature in your buying decision.  The quality is low and compression high, then the stuttering of faking the 1920fps kicks in and you end up with a subpar experience.

Here is a video sample of what appears to be a real clip from the Blackshark 2 Pro. You can easily notice the interpolation.

Now for some fun, The Slow Mo Guys have played with a huge amount of Gallium metal which becomes liquid at under 30 degrees C and looks pretty close to mercury without the toxicity. They do remind us that Gallium corrodes Aluminum on contact as it amalgamates with it, Aluminum which is what most cameras and lens cases are made of are pretty vulnerable,  so if you try this with your slow motion camera, be sure to use a barrier. -HSC

fps4000 first 480fps 4k Footage Revealed!

fps4000 first 480fps 4k Footage

Warning: The parent company of FPS cameras “The Slow Motion Camera Company Ltd.” went out of business and entered liquidation proceedings. No further development of cameras is expected. More information here on Google Search

It’s been a while since we’ve covered the fps4000 camera mainly due to development time taking longer than initially estimated. However, Graham Rowan the engineer behind the camera has now posted the first 4k 480fps footage shot in RAW on the fps4000 camera which uses a sophisticated memory arrangement on the onboard super-fast flash RAM to be able to record lengths of time unimaginable before on slow motion cameras at high resolution.

This camera is a very different kind of technology from regular high-speed cameras that record to volatile DRAM.  The fps series records to flash chips that are soldered to the mainboard and allow a variety of frames rates and resolutions depending on the sensor used but all is saved on the flash memory as a non-volatile stream of data.  Modern SSD chips are so good at re-allocating reading and writing bits that the life of the components is now measured in decades of regular use instead of a few years.  The fps4000 is using this technology fully to enable memory bandwidth magnitudes greater at a significantly reduced cost.

fps4000 first 480fps 4k Footage:

First UHD video from the fps4000
3840 x 2160 resolution 
480 frames per second

The Blue & Yellow Macaw video above shows the quality you can expect from full RAW DNG capture on the fps4000 camera at it’s higher-spec of 1280GB SSD £5,000 British Pounds plus Shipping and taxes. The fps4000 in 4k is also sold as a 1/2 speed 250fps maximum 4k UHD camera with 640GB SSD at a lower price of £3,500 British Pounds plus Shipping and taxes.  You can clearly see the 4/3 sensor used is delivering excellent quality even with 3.9µ pixels. Notice the 720 version on the same sensor size has a 13.5µ  pixel size which should prove to be outstanding in low light.

Also, note that the camera is able to record 60 full seconds of slow motion at 4k UHD 480p full resolution. This type of recording length is unmatched in any professional high-speed camera solution. We have only seen this type of rec length on custom lab camera systems and it usually involved a fast SSD disk array with fiber channel connections.

Here are the fps4000 configurations:

The lens options are varied with the Micro 4/3 mount as you can use any m4/3 adapter to Canon, Nikon, Minolta, Pentax, and other systems.

We should be able to test a review fps4000 unit in the not so distant future. Shooting 4k 480fps will create a mountain of data that will probably need an expanded drive array. The quality, however, will be worth every bit of space.  -HSC
