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. Consequently, the temporal resolution is an important factor ...
On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown . Conversely, if ...
Comparison of a slow down video without interframe interpolation (left) and with motion interpolation (right) Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate film, video or animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display ...
LFC helps ensure that when the framerate of a game is running below the minimum supported refresh rate of a display, the frames are displayed multiple times so the framerate remains in the supported refresh rate of the display and smooth gameplay is maintained. [14] AMD FreeSync Premium Pro adds luminance and wide color gamut requirements. [5]
In order to decrease render times (i.e. increase frame rate) the number of triangles in the scene must be reduced, by using low poly meshes. [ 3 ] Computer graphics techniques such as normal and bump mapping have been designed to compensate for the decrease of polygons by making a low poly object appear to contain more detail than it does.
Format identifiers like 576i50 and 720p50 specify the frame rate for progressive scan formats, but for interlaced formats they typically specify the field rate (which is twice the frame rate). This can lead to confusion, because industry-standard SMPTE timecode formats always deal with frame rate, not field rate. To avoid confusion, SMPTE and ...

However, the refresh rate still determines the highest frame rate that can be displayed, and despite there being no actual blanking of the screen, the vertical blanking interval is still a period in each refresh cycle when the screen is not being updated, during which the image data in the host system's frame buffer can be updated.
