Chronos 1.4 Survives 180Gs of Force Strapped on Mower Blade!

Chronos 1.4 Mower

The Tesla500 Youtube Channel is at it again with an impressive build and experiment. David Kronstein the creator of the Chronos has attached a camera to a specially modified mower and blade assembly to shoot what a lawnmower does directly on the blade’s edge.  The mower was only run at 1/2 speed, to avoid a camera failure, resulted in about 180 G-forces at the edge of the camera.

Needless to say, it really shows how good the camera is at withstanding abuse.  While we do not condone you do this with any camera it is cool to know it can be done and still have beautiful high speed imagery to go with it. Congrats to David for the successful build!   The G-forces involved would kill any living thing with a brain in seconds hence why a camera is a good subject, Please don’t try this at home!

Mi 8 and Mi 8 Explorer Get 960fps Firmware Update!

Mi 8 and Mi 8 Explorer

Xiaomi is soon releasing a new Firmware Update:  ROM – MIUI V10.1.2.0.PEHCNFI – based on Android 9 Pie and available first in China now.  The 2.1 GB update will include two new features that will make these phones more competitive. Search online for the ROM – MIUI V10.1.2.0.PEHCNFI  and be sure to follow the instructions while updating your phone.

The first feature is the inclusion of a 960fps slow-motion mode which is a big increase from the 240fps max setting before. As with other Xiaomi releases of the past, the slow motion samples are very hard to find or non-existent and there is a huge likelihood that they will use image interpolation from that same 240p to yield the 960fps. In a previous article, we referenced this test that showed the Xiaomi Mi Mix 3 using clear software interpolation to reach those frame rates. → Continue Reading Full Post ←

Chronos 1.4 Firmware 0.3.1 b9 Unleashes New Features!

Chronos 1.4 Firmware

The Chronos 1.4c team based in B.C. Canada has been hard at work unleashing the features of the camera hardware and adding software features that should make the camera more valuable to video professionals everywhere. The new firmware adds HDMI live mirroring support for monitoring which is clean and lets you record its output. Another feature is the inclusion of native CinemaDNG save format image sequences which retain 16bits of color data and allow you to really streamline the workflow without time-consuming conversions.

In our testing over the last 4 days, we have really put the firmware “available here” through its paces and found very minimal issues in the software related to usability but no freezes and rock solid operation over around 14hrs of operation.   By saving to CinemaDNG we have no issues with cards getting write space errors due to saving the 1.8MB files individually. We feel this format is really unleashing the camera’s quality fully with a faithful sensor capture representation. → Continue Reading Full Post ←

GoPro Hero 7 Black Has Killer Stabilization but Same fps!

GoPro Hero 7 Black

GoPro has released 3 new cameras including the Hero 7 Black which is now the flagship product for the company.  The key feature is HyperSmooth which is a predictive stabilization technology based on scene analysis and sensor telemetry to accurately anticipate motion and correct the image to generate a gimbal-like smooth appearance to the video.  When you see the footage it is clear it is a huge improvement compared to even the Hero 6 Black which had a pretty good stabilizer.

The Stabilization, however, is limited to  4k 30/60p and other resolutions below 120p but anything above 120fps will use the previous stabilization feature which is not predictive and have no stabilization support at all at 1080p 240fps which is the highest slow motion mode.  No 480fps or other higher fps settings are available as the camera uses both the same Hero 6 Black sensor and the same GP1 system chip for this new camera. → Continue Reading Full Post ←

iPhone Xs Slow Motion Official Apple Sample!

Apple has released a preview video showing the video capabilities of the iPhone Xs in 4k 30, 4k 60 and slow motion 1080p 240fps.  You can see in the liquid and sound part of the demo the quality delivered by the full HD slow motion but it is hard to judge per pixel sharpness and or artifacts from such a short high shutter video. We will need more real-world samples in order to see if there has been an improvement from the iPhone X of 2017.

We have isolated a part of the footage to see the slow-motion compression and we could detect aliasing in the edges, softness and compression artifacts which are typical of mobile phone high frame rates. The iPhone Xs seems to still have them to some degree. Color and motion on the codec seem to be excellent especially in 4k which looks extremely detailed and with more than acceptable dynamic range. → Continue Reading Full Post ←

Nikon Z7 and Z6 Mirrorless Have 120fps Slow Motion!

Nikon Z7 and Z6 Mirrorless

The slumbering Nikon has awakened to the mirrorless present and future and has shown their cards in a very strong but not class-leading mirrorless product line.  The Nikon Z7 & Z6 are nearly identical bodies with changes in the sensor and AF. The more expensive and higher resolution Z7 screams pixels with a 45.7MP Full Frame sensor  ISO 64–25600 range which should be a direct replacement for D850 users. The other Z6 is a better low light camera geared more at wedding shooters and videographers at 24.5MP which should produce outstanding low light  ISO 50–204800 with ISO expansion.

There is a lot to like in these cameras like a real 5 axis (5 Stop) IBIS stabilizer on the full frame sensor which also works on adapted lenses and works with Nikkor VR lenses from DSLR cameras to increase the 3 stops to a real 5 stops hybrid stabilization feature. The video modes offer 4k at 24, 25 and 30p which is so 2014 as is the 120fps full HD 1080p slow motion mode.  AF also changes between models at 493 points on the Z7 and 273 on the Z6. → Continue Reading Full Post ←
