1. A method for filtering in video encoding, comprising:
when (i) an intra block copy (IBC) mode is disabled for a chroma component of a block and the IBC mode is enabled for a luma component of the block or (ii) decoupled partitioning structures are applied to the luma component of the block and the chroma component of the block,
enabling at least one loop filter for the chroma component of the block;
determining a first sample of the luma component at a location in the block based on a first loop filter configuration that does not include the at least one loop filter; and
determining a second sample of the chroma component at the location in the block based on a second loop filter configuration that includes the at least one loop filter.
