An efficient scheme for video coding is presented which utilizes progressive fractal coding, called wavelet-based fractal approximation (WBFA), and motion compensation (MC). In the scheme, the MC error frames are encoded by the progressive fractal coding. Considering the severe localization of the MC errors, we use irregular sampling of domain blocks in a fine step instead of regular sampling of domain blocks in a coarse step that has been conventionally used. It is shown that the fractal video coder presented is competitive with or somewhat superior to H.263. It also has a relatively simple structure and reveals the characteristics of non-iterative decoding, and relatively fast encoding and decoding. It is found to be more suitable for low bit rate video coding
