A spatial concealment technique, based on the concept of the strength of an edge, is proposed for ‘digital dropout’ error, evident in old archived media. As long as the presence of pathological motion is observed in video sequences where current state‐of‐the‐art methods fail to reproduce correct information, such spatial restoration offers a much better solution in terms of quality and complexity. Furthermore, relevant edge‐based weighted interpolation is able to restore complicated edges and complex textures from the available neighbourhood. An experiment is performed on real video archives to evaluate the efficacy of the proposed technique.
