A method for inter-encoding a block of a colour image in H.264 high444 profile is proposed wherein the image comprises a first, a different second and a different third colour component. Said method comprises the steps of determining among two or more reference block candidates comprised in a different colour image that reference block candidate which has a corresponding first colour component matching said first colour component of said block at least as well as any of corresponding first colour components of the remaining reference block candidates, and encoding the second colour component of said block using a corresponding second colour component of the determined reference block. The reference block having a first colour component, which matches the corresponding first colour component of the block to-be-encoded, often is a good starting point for searching a reference block for a different second colour component of the block to-be-encoded.
