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.
Super 8 and 8 mm film formats – magnetic sound stripes are shown in gray. Super 8 mm film is a motion-picture film format released in 1965 [1] [2] [3] by Eastman Kodak as an improvement over the older "Double" or "Regular" 8 mm home movie format.

The HDMI TV standard (2003) allows both 44.1 kHz and 48 kHz (and multiples thereof). This provides compatibility with DVD players playing CD, VCD and SVCD content. The DVD-Video and Blu-ray Disc standards use multiples of 48 kHz only. Most PC sound cards contain a digital-to-analog converter capable of operating natively at either 44.1 kHz or ...
(In reality, over the course of an hour of real time, 215,827.2 video fields are displayed, representing 86,330.88 frames of film, while in an hour of true 24-fps film projection, exactly 86,400 frames are shown: thus, 29.97-fps NTSC transmission of 24-fps film runs at 99.92% of the film's normal speed.)
This new recurring feature shines a spotlight on these stations, starting with the one that inspired Petty’s quote, Los Angeles’ 88.5, the SoCal Sound. “‘Lifeboat’ is such a good ...
The film solution was to project each frame of film three times using a three-bladed shutter: a movie shot at 16 frames per second illuminated the screen 48 times per second. Later, when sound film became available, the higher projection speed of 24 frames per second enabled a two-bladed shutter to produce 48 times per second illumination—but ...
Although the decisions, styles and preferences of the filmmakers can affect the shooting ratio of a project greatly, the nature of the production (genre, form, single camera, multi-camera, etc.) greatly affects the typical range of the ratios seen – documentary films typically have the highest (often exceeding 100:1 following the rise of ...
