Abstract
Abstract A computer implemented method for editing a video frame is disclosed. The video frame comprises scan lines of a first video field interlaced with scan lines of a second video field, and the scan lines comprise a plurality of pixels, each having values representing image information. The method comprises displaying the video frame on a display screen of a computer system, the computer system having a processor and input means which are coupled to the display screen, receiving an input from the input means which indicates which of the first and second video fields of the video frame is to be edited and in response to the input, de-emphasizing the scan lines of the video field which is not to be edited.
