Abstract

The invention relates to editing of video information signals recorded on a record carrier, such as an optical record carrier are edited in an internal memory of the edit apparatus. Editing results in an edited stream of information, which includes a bridging fragment. Prior to recording the bridging fragment on the record carrier, the edited stream of video information around the edit point is made visible by retrieving the edited stream of video information directly from the internal memory, so as shorten the time required to make the edited stream of information visible on a display screen.
