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 ...
When using this method, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in the process. Slowing down the recording to increase duration also lowers the pitch, while speeding it up for a shorter duration respectively raises the pitch, creating the so-called Chipmunk ...
This increase in speed also increases the pitch of the audio by about 70.672 cents. [6] [better source needed] Digital conversion methods can correct for this increased speed and play the video back at its correct speed and pitch, at the expense of a decreased audio sample rate. [b]
For CDs, the 1× writing speed is equivalent to the 1× reading speed, which in turn represents the speed at which a piece of media can be read in its entirety, 74 minutes. Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 ...
The opposite is the case for time-lapse videos, where the effectively saved framerate is lower than for normal videos This means that the action visible inside the video runs at slower speeds than in real life, despite the indicated playback speed of ×1. This encoding method is used by the camera software of the following devices (incomplete ...
Clock rate or clock speed in computing typically refers to the frequency at which the clock generator of a processor can generate pulses used to synchronize the operations of its components. [1] It is used as an indicator of the processor's speed.
