    It usually refers to timing instability in the video.
    It was most noticeable in analogue video recordings where the difficulty in keeping video heads and capstans rotating at a constant speed resulted in a small amount of 'wobble' in the displayed pictures.

    With digital video this can be almost completely ironed out by buffering the digits and reading them out at the correct rate, ie timebase correction.

    I hope I haven't just muddied the waters here. :)
