What is MOV video format?

MOV is a video format developed by Apple. It is a type of file container that can hold many different video formats and multimedia. Because Apple created it, it only works with Apple products or video players, like Quicktime. MOV files often contain high bitrate video files with little to no compression.

Why is the QTFF file format so important?

The file format is object-oriented, consisting of a flexible collection of objects that is easily parsed and easily expanded.

The QTF phase values specify the phase timing of the peak positive QTF load contribution in the positive direction given by the direction conventions, relative to the time that the wave crest, trough or zero down- or up-crossing occurs at the primary motion position of the QTF phase origin.
