Animation of an interlaced CRT TV display, showing odd and even fields being scanned in sequence, to display a full frame. Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.
Shot on digital video in interlaced 60 fps, with some scenes shot on 35 mm movie film in 24 fps. Shown in cinemas in 24 fps and in interlaced 60 fps with 24 fps segments on DVD and Blu-ray. 1999 The Blair Witch Project: Daniel Myrick, Eduardo Sanchez: English Shot on Hi8 in interlaced 60 fps, with some scenes shot on 16 mm film in 24 fps.

In early cinema history, there was no standard frame rate established. Thomas Edison's early films were shot at 40 fps, while the Lumière Brothers used 16 fps. This had to do with a combination of the use of a hand crank rather than a motor, which created variable frame rates because of the inconsistency of the cranking of the film through the camera.
Integrated Multi Format Codec (MFC) provides encoding and decoding of MPEG-4/H.263/H.264 up to 1080p@30fps and decoding of MPEG-2/VC1/MPEG-4 video up to 1080p@30fps. Alma Technologies provides ultra low latency H.264 Encoder IP cores since 2011 capable of encoding Full HD video even on low cost FPGA devices. Standalone hardware implementations ...

For 30-fps standards, a process called "3:2 pulldown" is used. One film frame is transmitted for three video fields (lasting 1 + 1 ⁄ 2 video frames), and the next frame is transmitted for two video fields (lasting 1 video frame).
It converts 24 frames per second into 29.97 frames per second, converting approximately every four frames into five frames plus a slight slow down in speed. Film runs at a standard rate of 24 frames per second, whereas NTSC video has a signal frame rate of 29.97 frames per second. Every interlaced video frame has two fields for each frame.
The introduction of color television technology made it necessary to lower that 60 FPS frequency by 0.1% to avoid "dot crawl", a display artifact appearing on legacy black-and-white displays, showing up on highly-color-saturated surfaces. It was found that by lowering the frame rate by 0.1%, the undesirable effect was minimized.
