  2. Frame rate - Wikipedia

    en.wikipedia.org/wiki/Frame_rate

    Thomas Edison said that 46 frames per second was the minimum needed for the eye to perceive motion: "Anything less will strain the eye." [9] [10] In the mid to late 1920s, the frame rate for silent film increased to 20–26 FPS. [9]

  3. Orders of magnitude (time) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(time)

    10 −14 qs: The length of one Planck time (t P = / ≈ 5.39 × 10 −44 s) [3] is the briefest physically meaningful span of time. It is the unit of time in the natural units system known as Planck units. 10 −30: quectosecond: qs Quectosecond, (quecto-+ second), is one nonillionth of a second 10 −27: rontosecond: rs

    10 −12 s: One trillionth of a second. nanosecond: 10 −9 s: One billionth of a second. Time for molecules to fluoresce. shake: 10 −8 s: 10 nanoseconds, also a casual term for a short period of time. microsecond: 10 −6 s: One millionth of a second. Symbol is μs millisecond: 10 −3 s: One thousandth of a second. Shortest time unit used ...

  5. Key frame - Wikipedia

    en.wikipedia.org/wiki/Key_frame

    For example, a key frame may be output once for each 10 seconds of video, even though the video image does not change enough visually to warrant the automatic creation of the key frame. That would allow seeking within the video stream at a minimum of 10-second intervals.

  6. Slow motion - Wikipedia

    en.wikipedia.org/wiki/Slow_motion

    For example, if in the course of 10 seconds of capture, the capture frame rate is adjusted from 60 frames per second to 24 frames per second, when played back at the standard film rate of 24 frames per second, a unique time-manipulation effect is achieved.

  7. Time-lapse photography - Wikipedia

    en.wikipedia.org/wiki/Time-lapse_photography

    For example, an image of a scene may be captured at 1 frame per second but then played back at 30 frames per second; the result is an apparent 30 times speed increase. Processes that would normally appear subtle and slow to the human eye, such as the motion of the sun and stars in the sky or the growth of a plant, become very pronounced.

  8. Shutter speed - Wikipedia

    en.wikipedia.org/wiki/Shutter_speed

    The shutter rotation is synchronized with film being pulled through the gate, hence shutter speed is a function of the frame rate and shutter angle. Where E = shutter speed (reciprocal of exposure time in seconds), F = frames per second, and S = shutter angle: [15] =, for E in reciprocal seconds

  9. FPS - Wikipedia
