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 ←
We are constantly looking for high-speed camera bargains and one of the best places to find them is on eBay where used cameras go to find a new home. It is hard to judge the actual state of a product until you use it but that is why you can ask questions to the seller and reach a deal if needed. You also have to take into account that many cameras get used in dangerous situations to record events where no human can be close to like on a rocket launch pad or testing artillery.
Make sure if you purchase a camera to be given a determined time to test it and make sure it is working as described. The whole point of finding these bargains is to save a boatload of money compared to purchasing them outright from the manufacturer. HSC is not paid a commission or promotion fee for these listings so make sure you do your due diligence before buying, we are not affiliated with the sellers. This month a few diamonds in the rough were found that could really bring an edge to your slow motion shooting. Let’s dig in!→ Continue Reading Full Post ←
Sometimes all it takes to embark on a new project is some unexpected inspiration. On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment. The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.
You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”, you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane.→ Continue Reading Full Post ←
Sometimes getting a slow motion camera that performs to the spec you need and at a quality you can’t compromise on; means you have to get a professional piece of gear that is used but fully working. In that market you will still not find extremely cheap cameras but it will surely cost much less than what the hardware cost’s retail if you can live with a few scuffs or missing cables.
We have found a few options that are on the secondary market that fit the bill and these cameras offer exemplary performance and should perform reliably. Note that these are just recommended for you to look at and any decision to buy is your own. We are not responsible for any malfunction or transaction you establish with the sellers. We are only shedding some light on these options. → Continue Reading Full Post ←
Tom Guilmette is no stranger to slow motion work. His career shooting sports, nature and other subjects over 20 years has been quite prolific and without you knowing for the most part, his work has been probably displayed on your TV many times.
