In these contexts, frame rate may be used interchangeably with frame frequency and refresh rate, which are expressed in hertz. Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU , is able to generate frames, and refresh rate is the frequency at which a display shows completed ...
He also did research into frame rate, running a series of tests with 35 mm stock filmed and projected at various speeds, shown to audiences who were instrumented to biometrically test their responses. By measuring their EEG, he found that as the frame rate increased, so did the viewer's emotional reaction. The test subjects' brainwave activity ...
If the frame rate falls below the flicker fusion threshold for the given viewing conditions, flicker will be apparent to the observer, and movements of objects on the film will appear jerky. For the purposes of presenting moving images, the human flicker fusion threshold is usually taken between 60 and 90 Hz, though in certain cases it can be ...
The process of transferring 24 frame/s video at 25 frame/s rates is also the most common method for ingesting 24p film rushes into a non-linear editor.The resulting 25 frame/s video can then be transferred into a non-linear editing system at 25 frame/s, maintaining the 1:1 frame correspondence between film frames and video frames.
59.94p is the frame rate used for 720p broadcast HDTV in the USA and other countries with an NTSC broadcasting history, as specified in SMPTE 296M. The exact rate is 60000/1001, which works out to be slightly over 59.94 frames per second. 60p is a progressive format that is very close to the 60000/1001 broadcast system used in some countries.
On larger CRT monitors (17 in or 43 cm or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps ...
The rate of NTSC video (initially monochrome, only, but soon thereafter monochrome and color) is 29.97 frames per second, or one-thousandth slower than 30 frame/s, due to the NTSC color encoding process which mandated that the line rate be a sub-multiple of the 3.579545 MHz color "burst" frequency, or 15734.2637 Hz (29.9700 Hz, frame rate ...
There is a large difference in frame rate between film (24.0 frames per second) and NTSC (approximately 29.97 frames per second). Unlike the two other most common video formats, PAL and SECAM, this difference cannot be overcome by a simple speed-up, because the required 25% speed-up would be clearly noticeable.
