1. A system comprising:
a memory configured to store data for a picture; and
an encoder coupled to the memory and configured to:
determine that a parent coding unit of a child coding unit of the picture is not predicted in an intra-block copy mode;
determine that an activity level of the child coding unit is less than a threshold level; and
skip an intra-block copy search for the child coding unit in response to determining that the parent coding unit is not predicted in the intra-block copy mode and in response to determining that the activity level is less than the threshold level.
