Destin from SmarterEveryDay has posted an incredible video explaining how a lawn mower cuts grass. It is way more interesting and memorable than you might think. The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even. The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera. Highly Recommended to watch and subscribe to SmarterEveryDay for more great content! -HSC
There has been a lot of excitement about the OnePlus 6 for the past two weeks and while the slow motion feature is not the first feature you look for, it may be the biggest deal in phone slow motion in several years. The duration eclipses the competition by leaps and bounds at 3.75 seconds of recording vs 0.2s or 0.4s for the competition.
We have found a few samples that show the phone at 480fps 720p and 240fps 1080p quality which right off the bat show that the phone is capable but still a long way from competing with professional slow-motion cameras like the edgertronic series or Chronos 1.4 in both recording time and image quality. Even with all of these negatives, the OnePlus 6 does bring the technology forward by allowing phone users to record enough slow-motion footage to make it usable for publishing on the web or specific uses in education or sports analysis.
The full specs are official now and the OnePlus 6 is now considered a flagship phone by any measure you can throw at it. It has massive memory, speed and a price that will not break the bank at just $529 USD for the smaller capacity 64GB version. It has dual cameras and 4K shooting at 60FPS, 1080p at full 240FPS, and our favorite spec 720p at 480FPS.
Gone is the 960fps spec of phones like the Samsung Galaxy S9 & Sony Xperia XZ2 but with the added benefit of shooting 1800 frames of it which translates to 60 seconds playback “1 Minute” at 30p on the OnePlus 6. So an entire usable minute of slow motion at 720p will be a welcomed addition to any slow motion fans and while quality will have to be seen and analyzed, it already makes for a better overall experience than the 0.2 seconds recording of the competition.
The Lumix TS7 by Panasonic “TS7 in the US, Canada, FT7 outside of North America” is a well-rounded package when it comes to pricing and features. It is a 4k 30/25/24 ready camera and it can go underwater 31 Meters or 102ft plus all the cool ruggedized features you might expect on a camera of this kind like being crush-proof up to 220lbs/100kg and freezeproof down to -10 °C / +14 °F. It is a real alternative to smaller action cameras like the GoPro, Xiaomi Yi 4k+ and Sony Action Cam series.
The lens is a 28–128 mm 35mm equivalent 4.6x zoom range which is quite sharp across the range as we have seen from samples. The main issue with this camera is the small 1/2.3″ BSI sensor and the fact that it packs 20MP or a resolution of 5184 x 3888px which is a little too cramped to be ideal for low light or in our view underwater performance without added bright artificial lighting. ISO goes from a low of 80 to a high of 6400 which probably is already pushing it too much. This camera would have been a better bet with a 10 or 12MP BSI sensor to maintain some edge in low light for the competition.
We were excited last September when Sony announced a trio of Palmcorders based on their latest 1″ stacked image sensor. The FDR-AX700, the HXR-NX80 and the PXW-Z90V share essentially the same sensor and lens along with other common features but differ when it comes to codec bit rates, broadcasting output like SDI out and or HDMI but what interests us is the HFR high frame rate mode.
The Sony RX100 and RX10 series share the same 1″ stacked CMOS sensor in their latest iterations to these cameras but with a new form factor that is aimed at more professional shooters, there is a lot of expectations to see if quality has improved in Slow Motion. We have gone thru the manuals on the cameras and have not been able to find the exact resolution specs when recording HFR but we estimate they are identical to the latest RX10 IV all in one prosumer camera.
We find that while the video is simple, it does a good job in explaining the methods on Apple’s iOS and Android to get slow motion footage ready for posting on the web or social media. There is some basic editing and trimming for cutting the nonaction parts.
