Recent studies demonstrated that blood pressure (BP) can be estimated using pulse transit time (PTT). For PTT calculation, photoplethysmogram (PPG) is usually used to detect a time lag in pulse wave propagation which is correlated with BP. Until now, PTT and PPG were registered using a set of body-worn sensors. In this study a new methodology is introduced allowing contactless registration of PTT and PPG using high speed camera resulting in corresponding image-based PTT (iPTT) and image-based PPG (iPPG) generation. The iPTT value can be potentially utilized for blood pressure estimation however extent of correlation between iPTT and BP is unknown. The goal of this preliminary feasibility study was to introduce the methodology for contactless generation of iPPG and iPTT and to make initial estimation of the extent of correlation between iPTT and BP "in vivo." A short cycling exercise was used to generate BP changes in healthy adult volunteers in three consecutive visits. BP was measured by a verified BP monitor simultaneously with iPTT registration at three exercise points: rest, exercise peak, and recovery. iPPG was simultaneously registered at two body locations during the exercise using high speed camera at 420 frames per second. iPTT was calculated as a time lag between pulse waves obtained as two iPPG's registered from simultaneous recoding of head and palm areas. The average inter-person correlation between PTT and iPTT was 0.85 0.08. The range of inter-person correlations between PTT and iPTT was from 0.70 to 0.95 (p
If you don't have the best memory card for your camera, then you're not going to get the most out of your photoshoots. With so many options for speed, capacity, brand, compatibility, and price available, you might initially feel overwhelmed. However, we've broken down the best memory cards available to show you which ones are best for you.
Every digital camera uses memory cards for storing your videos. Choosing the right one, however, can sometimes be overwhelming. After all, it is an important decision. This straightforward three-step guide is designed to help you find the best memory card for your specific use case.
Some higher-end DSLR and mirrorless cameras support multiple cards, making the decision a bit more complicated. For example, the Sony a7S III supports SDXC and CFexpress Type-A cards. In situations like this, it is generally recommended to pick the type with faster write speed, which, in this case, is Cfexpress Type-A. Your camera usually supports this faster card for a good reason (more about that below).
Write speed determines how fast data can be saved on the memory card. This is especially critical when dealing with higher-resolution videos. If the memory card is too slow and unable to adequately handle the incoming data during recording, it may start dropping frames or store the video in lower than expected quality. In worst-case scenarios, your camera may stop recording altogether.
If not stated otherwise by the manufacturer, the write speed marked on a memory card usually does not indicate the minimum sequential write speed but the maximum a card can reach. Even though paramount, you should not be basing your purchase decision solely on the maximum write speed.
The highest minimum write speed any SD card can sustain is determined by the highest Speed Class marking on the card. Symbols of the Speed Class, UHS Speed Class, and Video Speed Class (with a corresponding number) indicate a specific speed at which your camera or any other device can write data on the card consistently. The higher the rating, the more data you can write to the card in the same amount of time.
One SDXC card can be certified in every speed class. It is so because there is a lot of overlap between the classifications. For example, Speed Class rating C10, Ultra-High Speed Class rating U1, and Video Speed Class rating V10 each refer to a memory card that has a minimum sequential write speed of 10MB/s. Similarly, a V60 card with a minimum sequential write speed of 60MB/s is pretty much automatically handed the Speed Class C10 (10MB/s) and UHS Speed Class U3 (30MB/s) rating as well.
For that reason, whenever looking for an SDXC memory card for video recording, you can pretty much just focus on the Video Speed Class and ignore the rest. The following chart helps to navigate the speed classes easier.
As mentioned before, if you are one of the lucky ones whose camera supports the CFexpress Type A cards alongside the SDXC cards, go with these. They not only ensure you get the maximum out of your camera, but they are also the most future-proof option, as more and more camera manufacturers adopt the format.
A faster read speed decreases your wait time by allowing you to transfer data from the card to your computer faster. That means you can get to editing and sharing your work a lot quicker. Faster read speeds are critical for projects with short deadlines requiring quick turnovers.
Video bitrate, frame rate, length, and format each affect the size of your video files. For instance, a single minute of 1080p video may take only around 130MB of space. At the same time, one minute of ProRes 4K video at 880 Mbits/s will consume roughly 5.3GB. That works out to 318GB every hour. A lot, to say the least. You definitely want to use higher-capacity cards if you are recording at such high data rates.
When it comes to stocking up memory cards for video recording, it is critical to choose wisely. There are close to quadrillion memory cards out there and not all of them can meet the demands of modern cameras and your workflow.
The filmmaking term for shooting slow-motion video (or high-speed video) is over-cranking. Technology has progressed a lot since the days of film, and the realm of high-speed filmmaking has taken on new dimensions; there are a wide range of options for everyone from the broadcast professional to the hobbyist.
This camera is fairly prosumer with a price tag of around 2800 USD. The real benefit of this camera is quality high-speed recording on a tiny camera. Users can select a recording speed of 300 fps, 600 fps, or 1200 fps. Resolution drops with the highest frame rates as follows: 512 x 384 (300 fps), 432 x 192 (600 fps), 336 x 96 (1200 fps).

A high-speed camera is a device capable of capturing moving images with exposures of less than 1/1,000 second or frame rates in excess of 250 fps.[1] It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used film to record the high-speed events, but were superseded by entirely electronic devices using either a charge-coupled device (CCD) or a CMOS active pixel sensor, recording, typically, over 1,000 fps onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena.[2]
A normal motion picture film is played back at 24 frames per second, while television uses 25 frames/s (PAL) or 29.97 frames/s (NTSC). High-speed film cameras can film up to a quarter of a million fps by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for stopping and starting the film behind a shutter which would tear the film stock at such speeds. Using this technique one second of action can be stretched to more than ten minutes of playback time (super slow motion). High-speed video cameras are widely used for scientific research,[4][5] military test and evaluation,[6] and industry.[7] Examples of industrial applications are filming a manufacturing line to better tune the machine, or in the car industry filming a crash test to investigate the effect on the crash dummy passengers and the automobile. Today, the digital high-speed camera has replaced the film camera used for Vehicle Impact Testing.[8] 041b061a72
