A video processing apparatus generates an output frame from two or more input images by deriving pixels to interleave between lines of pixels of a base field. The pixels are derived from one of: a first pixel generator generating a pixel value from one or more fields other than the base field, dependent on a respective motion vector having a sub-pixel resolution; or a second pixel generator generating a pixel value from other pixels of the base field. A spatial phase-correcting filter receives an input group of derived pixels including a current derived pixel, and generates an output phase-corrected current pixel value. A pre-compensation mechanism, operable if a pixel forming part of the derived pixels group has been generated by the second pixel generator, applies spatial phase alteration to approximate the phase of that pixel to the phase of the current derived pixel.
