There are simple 2-line and 4 line converters. The 2-line converter creates a new line by comparing two adjacent lines, whereas a 4-line model compares 4 lines to average the 5th. Interfield interpolation reduces judder, but at the expense of picture smearing. The greater the blending applied to smooth out the judder, the greater the smear ...
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.
In the case of material shot on video, improvements in smoothness just from having a higher refresh rate may be barely noticeable. [11] In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown).
For instance, a cycle that starts with film frame B yields a 3:2 pattern: B-B-B-C-C-D-D-D-A-A or 3-2-3-2 or simply 3–2. In other words, there is no difference between the 2-3 and 3-2 patterns. In fact, the 3-2 notation is misleading because according to SMPTE standards for every four-frame film sequence the first frame is scanned twice, not ...
Many motion blur factors have existed for a long time in film and video (e.g. slow camera shutter speed). The emergence of digital video, and HDTV display technologies, introduced many additional factors that now contribute to motion blur. The following factors are generally the primary or secondary causes of perceived motion blur in video.

The process of transferring 24 frame/s video at 25 frame/s rates is also the most common method for ingesting 24p film rushes into a non-linear editor.The resulting 25 frame/s video can then be transferred into a non-linear editing system at 25 frame/s, maintaining the 1:1 frame correspondence between film frames and video frames.
