Two sizes of images are typically used: 1920×1080 ("1080i/p") and 1280×720 ("720p"). Confusingly, interlaced formats are customarily stated at 1/2 their image rate, 29.97/25 FPS, and double their image height, but these statements are purely custom; in each format, 60 images per second are produced. A resolution of 1080i produces 59.94 or 50 ...
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.
When transferred to NTSC television, the rate is effectively slowed to 23.976 FPS (24×1000÷1001 to be exact), and when transferred to PAL or SECAM it is sped up to 25 FPS. 35 mm movie cameras use a standard exposure rate of 24 FPS, though many cameras offer rates of 23.976 FPS for NTSC television and 25 FPS for PAL/SECAM.
Also, other patterns have been described that refer to the progressive frame rate conversion required to display 24 frame/s video (e.g., from a DVD player) on a progressive display (e.g., LCD or plasma): [11] 24 frame/s to 96 frame/s (4× frame repetition): pulldown is 4:4; 24 frame/s to 120 frame/s (5× frame repetition): pulldown is 5:5
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 ...
NTSC to PAL conversion also tends to blur each film frame into the next, and so is seen as a sub-optimal way to view film footage. 30p can be preferable over 24p since performing a standards conversion to 25i PAL has fewer technical complexities – any NTSC–PAL converter will do. The larger differences between the 30p and 25i framerates will ...
[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 ...
A few film formats have experimented with frame rates higher than the 24 fps standard. The original 3-strip Cinerama features of the 1950s ran at 26 fps. [3] The first two Todd-AO 70 mm features, Oklahoma! (1955) and Around the World in 80 Days (1956) were shot and projected at 30 fps. [4] Douglas Trumbull's 70 mm Showscan film format operated ...
