Abstract
A multiple access record/playback device, such as a digital disk recorder, is used for video effects, such as simultaneously providing a preview video signal and a time offset production video signal of the same video image or simultaneously providing multiple views of the same video image. An input video signal is selected from a plurality of input video signals for storing on the multiple access record/playback device. The input video signal is read out for display from the multiple access record/playback device from an identified start point at two times to provide simultaneously a preview video signal and a time offset production video signal for the same video image. Alternatively the plurality of input video signals of the same video image are stored simultaneously on the multiple access record/playback device, and one of the plurality of input video signals is selected for reading out for display from an identified start point at two times to provide simultaneously the preview video signal and the time offset production video signal. For analysis the plurality of input video signals stored on the multiple access record/playback device may be read out for display synchronously and simultaneously for analysis of the video image from different views.
