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.→ Continue Reading Full Post ←
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.→ Continue Reading Full Post ←
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! Watch the video below:→ Continue Reading Full Post ←
Ever wondered how super slow motion in the past was capable of multi-thousand fps performance with just film exposures? Well, they used customized camera rigs that combined multiple rolls of films, mirrors, and synch cables to essentially get a result beyond what the limitations of the equipment forced upon the shooter.
In a very cool video by Camera Tech on Youtube from 2015 they were able to get a custom mirror rig to shoot simultaneously on two GoPro cameras with a semi-translucent angled mirror that splits the light to each camera lens by 50% making it possible to sum both frame rates in post by alternating the frames captured by both cameras with a very slight time difference equivalent to 1/frame rate expected.→ Continue Reading Full Post ←
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 ←
The Chronos 1.4 team has been hard at work on firmware improvements. The latest pre-released software patch shared with HSC improves the h.264 file quality at the pixel level by using a new demosaic algorithm to better match the real camera output. We did a few sample tests to see how big an improvement it is and also to maybe ditch the slow and space eating RAW 16bit workflow which is our preferred file saving format as it retains all the sensor information.
The new improvements are already available to the community as a beta in this post. It is very stable it should immediately improve the way you work with the camera. Also, a new roadmap of upcoming firmware releases was shared in the forums which include HDMI monitoring and a complete OS change to Debian Linux from the current Arago distro for the camera which should improve development and speed in implementing features.→ Continue Reading Full Post ←
