While it was true that each picture element was polled and sent only 29.97 times per second, the pixel location immediately below that one was polled 1/60 of a second later, part of a completely separate image for the next 1/60-second frame. At its native 24 FPS rate, film could not be displayed on 60 Hz video without the necessary pulldown ...
[1] [2] VFR is especially useful for creating videos of slideshow presentations or when the video contains large amounts of completely static frames, as a means of improving compression rate, or if the video contains a combination of 24/25/30/50/60 FPS footages and the creator or editor of the video wishes to avoid artifacts arising from ...
Similarly, 60i is shorthand for 60/100.1% fields per second. Some NLE programs may refer to 23.976 as 23.98, causing a small amount of confusion. Note that with 23.976 fps time code, the "second" counter is still increased after 24 frames, even though 24 frames add up to slightly more than a real second.
To convert 24 frame/s film to 29.97 frame/s (presented as 59.94 interlaced fields per second) NTSC, a process called "3:2 pulldown" is used, in which every other film frame is duplicated across an additional interlaced field to achieve a framerate of 23.976 (the audio is slowed imperceptibly from the 24 frame/s source to match). This produces ...
In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
The TV can natively display 240 frames per second, and perform advanced motion interpolation which inserts between 2 and 8 new frames between existing ones (for content running at 60 FPS to 24 FPS, respectively). For active 3D, this framerate would be halved.
Shot on Hi8 in interlaced 60 fps, with some scenes shot on 16 mm film in 24 fps. Shown in cinemas, DVD, and Blu-ray in 24 fps. The 2024 remastered Blu-ray from second sight is presented in interlaced 60 fps with 24 fps segments. 2001: Soarin' Over California: Rick Rothschild English: 48: IMAX HD, Disney California Adventure ride [7] [8] 2006 ...
Sony RX100 IV, V, VI and VII: High Frame Rate (HFR) mode records at 240 fps up to 1,000 fps for 3–7 seconds. This is saved at 24 - 60 fps, i.e. from 1/4x down to 1/40x speed.
