The invention encoding at least one picture (IN) cut into partitions (PA1, PA2, ... PAn), characterized in that it implements, for a current partition to be coded, the steps of: - selection (C2) at least one causal partition already encoded and then decoded, - calculation (C4) of at least one optimal encoding parameter (idx1, idx2, ..., IdxK) associated with said selected causal partition, according to a predetermined encoding performance criterion, on a competitive basis with a plurality of coding parameters applied to said selected causal partition, - coding of the current partition using said optimum encoding parameter calculated.
