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 individual timecode for each frame. VFR is especially useful for creating videos of slideshow presentations or when the video contains large amounts of completely static frames, as a means of improving compression rate.
Famous quotes containing the words variable, frame and/or rate:
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
“Faith, I have been a truant in the law,
And never yet could frame my will to it,
And therefore frame the law unto my will.”
—William Shakespeare (1564–1616)
“As a novelist, I cannot occupy myself with “characters,” or at any rate central ones, who lack panache, in one or another sense, who would be incapable of a major action or a major passion, or who have not a touch of the ambiguity, the ultimate unaccountability, the enlarging mistiness of persons “in history.” History, as more austerely I now know it, is not romantic. But I am.”
—Elizabeth Bowen (1899–1973)
