pulldown is a process pf transferring film to video.film is natively shot at 24 frames per second while video is 30 frames or 60 fields per second.pulldown in simplest explanation changes 4 frames of film to ten frames of video.

well,pulldown is the process of transferring film to video. That sounds easy, but it is actually pretty complicated. Modern film is projected at 24 frames per second. Video, in the U.S. and many other countries, is displayed at 60 pictures per second. So, when we want to convert film content to video, as long as we can come up with a way to repeat each film frame an average of 2.5 video pictures, our job is done. One way to do this is to repeat the first film picture 2 times, the second film picture 3 times, and so on: 2, 3, 2, 3. You might have heard of 2:3 or 3:2 pulldown — this is where those numbers come from. 2:3 and 3:2 pulldown are the same thing — they are not ratios, like they first appear to be.

Pulldown process restores the proper speed of the film on video, it generates some unpleasant problems. Two sequential video frames within every five video frame sequence contain images from different film frames. If there is movement of the images on film, 40% of the video frames will contain visually distorted information.

hi disha:-
Modern high-resolution or high definition displays advertise “pulldown removal” for optimal display of film content, such as that found on DVD. Just what is pulldown, where does it come from, and why would you want to remove it? Pulldown is a method that was created as a way to distribute film content in the world of video.

The general term used to describe committing motion picture film material to video. So named because a projector or telecine machine typically has a "pulldown claw" to advance the film one frame at a time past the gate, or window through which the projection beam or other light source passes. The most common pulldown procedure is called 3-2 (or 2-3) pulldown (q.v.) since for immediate broadcast, alternating film frames are scanned three times and twice respectively before the pulldown claw is activated. The slight slowing of a motion picture, video, or audio program for synchronizing purposes, or to cause it to run in the time allotted without editing of material. Pullup -- The slight speeding up of a motion picture, etc. for the purpose immediately preceding.

The process of matching the frame rate of film (24 frames per second) to the frame rate of video (30 frames per second).

Pulldown is the process of matching the frame rate of film (24 frames per second) to the frame rate of video (30 frames per second). In 3:2 pulldown, one frame of film is converted to three fields (1-1/2 frames) of video, and the next frame of film is converted to two fields (1 frame) of video. THis process is repeated (yielding 3 fields of video, 2 fields, 3 fields, 2 fields...) until the film is fully converted to a video of approximately the same length (duration). Most scan doublers, quadruplers, and scalers use the premise that two fields of video equal one frame, but video created via 3:2 pulldown does not follow that pattern.

The technique used to convert 24 frames per second film to 30 frames per second video. Every other film frame is held for 3 video fields, resulting in a sequence of 3 fields, 2 fields, 3 fields, 2 fields, etc.
