The Z Cam E2 has finally started shipping and is now available for direct order at their site. The camera caught our attention for its low price of just $1999 and the high frame rate features of 240fps 1080p and 120fps 4k. It seems to be using the same 4/3 sensor as the great Panasonic GH5s but with extended features.
The camera company ZCam has also released some samples in a variety of scenarios so you can see what the camera is capable of. At first inspection, it is clear this camera is a clear step up from the Z Cam E1 which had some image quality issues. The E2 seems to go out of the box ready to produce class-leading imagery and offer some very nice high frame rate action. There are also some rumored comments that suggest the team is testing 300fps at 720p as an added bonus for future software.→ Continue Reading Full Post ←
Blackmagic Design may have just solved the problem of RAW video capture for any camera and every type of user. In essence, it gives the benefits of RAW capture while allowing flexibility in file size depending on production needs. It is a compressed format but by using a clever demosaic algorithm that happens in-camera, it shrinks the file size much more than other formats while preserving quality and RAW features like White Balance, ISO, exposure, NR, clarity and color bit depth.
For Slow motion cameras, it may be the codec of the future as it will allow the best quality without the enormous file sizes associated with image sequences like DNG or other RAW formats. Being open source and free of licenses it aims to be adopted by the entire industry faster than other formats and will be free of the platform-specific nature of codecs like Apple’s ProRes which only works on Mac OS X. The Blackmagic RAW beta is already available here!→ Continue Reading Full Post ←
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 ←
Nikon has either gone crazy or has analyzed a market that is actually alive and well when it comes to all in one prosumer compact cameras. The P900 was a best seller for several years in the segment with an 83x optical zoom formula of 24-2000mm equivalent. Now the new P1000 increases that range by 1000mm to do a previously ludicrous spec of 24 wide-angle to 3,000mm telephoto range or 125x optical zoom.
The sensor is tiny at 1/2.3″ the same as small compact cameras and just slightly larger than the typical phone sensor of 1/3″. This is what makes it possible for the camera to create such a zoom range without the lens being larger than a Napoleonic war artillery cannon. The video modes are decent with 4k 30p but the high-speed modes are lackluster which is a shame considering this camera could be used effectively for extreme wildlife shots in super slow motion.→ 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.
The Rosalind Franklin Institute has started the development of a 100 million fps high-speed camera that will operate at 1-megapixel resolution to scan how new cancer drug treatments along with ultrasound interact to create effective cures for the deadliest forms of the disease. This type of performance is unheard of in that resolution and would herald a new way of looking at minute amounts of time that happen so fast no detector so far has been able to capture them at a usable resolution.
To put this in numbers, the camera will be able to capture a 100,000,000,000,000or One Hundred Trillion Pixels per second or one hundred million megapixels/sec. Those are staggering numbers and if saved in a raw format it would take a megabyte per frame or 100 Terabytes of imaging data/second. That will be one extremely large frame buffer. With compression techniques and image optimization you could probably get that number lower but if played back at 30fps it would take 38 days to see a single 1-second video, staggering speed for sure!→ Continue Reading Full Post ←
