Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing , yields abrupt motion artifacts, and degrades the video quality.
Variable frame rate (or VFR) is a term in video compression for a feature supported by some container formats which allows for the frame rate to change actively during video playback, or to drop the idea of frame rate completely and set an individual timecode for each frame.
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.
This is a list of films with high frame rates.Only films with a native (without motion interpolation) shooting and projection frame rate of 48 or higher, for all or some of its scenes, are included, as are films that received an official post-conversion using technologies such as TrueCut Motion.
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
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 ...
Television standards conversion is the process of changing a television transmission or recording from one video system to another. Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem.
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
