see this page: http://in.mathworks.com/help/vision/ref/vision.videofilereader.step.html here 'step' is used to go to next frame, is there any way to come back to last passed frame.

Going back is not possible with that system object.

If you were to use VideoReader then the way to go backwards would be to set the CurrentTime property to a prior time before doing the readFrame
