Sony has released specs for a new IMX Cellphone oriented sensor that has a whopping 48 Megapixel photosite grid with a new Bayer altered pattern of quad pixel colors that aims to quadruple the dynamic range of the signal and increase detail retention significantly by supersampling every photosite and creating a final 12MP image with excellent characteristics.
As far as frame rates go we were glad to see very high-end read-out speeds for this sensor as full 4k video can max out at 90fps and other high fps settings include 1080p 240fps full area downsampling and 720p 480fps but with a cropped windowed frame extraction. At 48MP or 12 regular De-Bayered then we expect the crop to be quite extreme at the 720p mode unless they do a 4 or 6MP downsample.→ Continue Reading Full Post ←
TIME has posted a series of videos on the reaction of fans to the World Cup final game between France and Croatia shot by Videographer James Autery on the streets of New York City. While he only used 120fps video capture, it is enough to fully show human reaction detail. Follow the link below to watch them at their official site:
Ever wondered how to use slow-motion footage effectively with Premiere Pro CC from Adobe’s Creative Cloud? This quick tutorial by YouTubers Becki and Chris will go through the basics of capturing, editing and organizing the footage for a consistent workflow. They used cameras like the GoPro Hero 5 Black, Sony a7s II, and the DJI Osmo to capture the footage.
Their techniques will apply to any camera that shots high frame rates like 60p and above. Maybe in a future tutorial, they are able to use higher frame rate footage from more capable cameras and even use the optical flow feature to really slow things down in post.

Sony has released an altered version of the RX100 V camera for the Australian market which keeps all of the good features of the RX100 V camera but also changes it’s internals and software to allow for increased buffer space for images and video in HFR mode and allows the AF module to include the Fast Hybrid AF system with 315 focal-plane phase-detection points to match that of the RX100 VI which was announced just last month.
The memory increase itself allows for 24fps continuous shooting with a buffer up to 148 JPEG frames. That also allows improved High Frame Rate recording times, and fast continuous AF with stills and while recording UHD 4K video. Recording of 7 seconds of recording in Shoot Time Priority at the 240 fps setting which matches the one in the regular RX100 V and RX100 VI in America.→ Continue Reading Full Post ←
With the Samsung Galaxy S9 and S9+ on the running for the best slow motion smartphone of 2018, recent leaks if confirmed could make the Note 9 an even better proposition for high frame rate enthusiasts. As with all rumored and leaked info, it could be false or inaccurate when compared to the final specs. However, this phone is scheduled for an August 9th, 2018 reveal at a special event.
The most encouraging info on the new Phone will be the use of a new ISOCELL sensor capable of full HD recording at 960fps. Which will be a big improvement from the Galaxy S9’s 720p 960fps. That phone only records 0.24sec worth of 960p video so it would be ideal if the Note 9 was able to at least double that time but at full HD resolution. The phone is expected to cost at least $960 based on the Note 8 price so it will not be cheap to get this kind of performance.→ Continue Reading Full Post ←
NVIDIA has been hard at work on the problem posed by high frame rate interpolation of video data shot on lower fps. We have had this tech since the late 1990s with the advent of Twixtor and refined over the decades in systems like Twixtor Pro and Adobe’s Optical Flow in After Effects. You are still not getting real temporal detail data since the frames are created by extrapolating velocity and direction vectors plus pixel values between frames to get the result.
We explored this technique in our post on interpolation here and why it is no substitute from a real slow motion camera solution. NVIDIA’s new method uses machine learning along with 11,000 videos to arrive at a more convincing result. Considering the relatively small sample size we can imagine a future where hundreds of thousands or millions of footage samples are used to generate near flawless interpolation. This technique takes some serious computation and data sets so as of now it is not really ready for the mass market but that could change with the cloud very soon.→ Continue Reading Full Post ←
