Beyond the press, Youtube channel from Finland has posted an incredible video that showcases the power of 72 Chronos 1.4 cameras in the Chronos Ring system to deliver 330,000 fps making it able to capture Oxy-Acetylene gas explosions at ridiculously slow speeds. It is so fast that a single camera would have to travel at 43.175 Kilometers/second which is over 5x faster than the International Space Station. That is the power of daisy-chaining slow motion gear that is considerably inexpensive compared to high priced options and giving you incredible results. Props for the Team at Krontech.ca for sharing their system with the world. More info about the Chronos Camera and the Chronos Ring at: https://www.krontech.ca
Now that the Sony Xperia 1 has been reviewed by more people, there are now sufficient video samples at 960fps to make a judgment on the performance of the slow motion mode. As you may recall, the phone is only capable of recording 0.1 seconds at 960p at full HD 1080p and 0.2 seconds at 720p at the same frame rate. That translates to a maximum of 3.2 seconds at 1080p played back at 30p and 6.4 seconds at 720p 30fps.
There is no increase in recording time from the XZ2 and XZ3 phones which had essentially the same feature as the Xperia 1. We, however, saw a little better color reproduction and slightly better artifact handling on the new phone but so minute an edge that we simply cannot recommend upgrading for this feature or considering it over other 720p slow motion phones like the Galaxy S10 or OnePlus 7.
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.
To better encapsulate the slow motion happenings of the web we are starting a new post type called Fraction/s as in “Fractions of a Second” that shows anything and everything related to slow motion that has happened recently. This is based on the fact that high speed imaging hardware releases have been stabilizing and slowing down compared to previous years. This way we can better cover anything small or large related to this craft.
Thanks to our readers who have submitted a lot of this information which sometimes escapes us. There is a lot of interest in slow motion related information but it is easy to get buried in the mountain of daily information. We hope that we cover many of these occurrences so you get to see them.
So now that the Xperia 1 phone has started shipping to some parts of Asia and Oceania it is time to see what the initial slow motion 960fps samples look like. It seems that the length of the playback video is unchanged at 6.4 seconds for 720p and 3.2 seconds for 1080p. So 96frames are recorded at 1080p 960fps and 192frames at 720p. This is the same restrictive spec for three years in a row by Sony.
You would think by now the phone could have increased the slow motion buffer to something useful like at least half a second instead of 0.2sec for 720p and 0.1sec for 1080p. Think again, it seems we will not get anywhere near usable times in 2019 from the Xperia Line again. Your best bet for recording on Sony will be to get a camera like the excellent RX Series that allow much longer recording times and greater resolution.
This week Sony Announced Xperia 1, the successor to their previous flagship the Xperia XZ3 with a few new features and a very ultra-wide 21:9 CinemaWide™ 4K HDR OLED display which creates cinematic like aspect ratio UHD video with what they claim Cinealta HDR color science. The footage does look impressive at first glance but we have to remember the small sensor on phones simply cannot compete with an APS-C or Full Frame Cinealta camera sensor.
The good news is that the phone continues to offer the 960fps Full HD 1080p spec as in previous phones the XZ series. Sony chose to not allow initial samples of footage shot in various modes including the high speed because the phone is not finalized. From anecdotal evidence, it seems to compare favorably with their Xperia XZ3 but with some better color characteristics due to the Cinealta heritage color LUTs.
