Offset and quantization interval for cross component sample offset

A method of video encoding performed at a computing system having memory and one or more processors, the method comprising:

• receiving video data comprising a plurality of blocks, including a current block;
• when the current block has a first property, determining a quantization step size for the current block using a first look-up table;
• when the current block has a second property, determining the quantization step size for the current block using a second look-up table, wherein the second property is different than the first property, and wherein the second look-up table is different than the first look-up table;
• and
• encoding the current block using the determined quantization step size.

A non-transitory computer-readable storage medium storing a video bitstream that is generated by a video encoding method, the video bitstream comprising:

• coded information for a plurality of blocks including a current block;
• and
• wherein the video encoding method comprises:
• when the current block has a first property, determining a quantization step size for the current block using a first look-up table;
• when the current block has a second property, determining the quantization step size for the current block using a second look-up table, wherein the second property is different than the first property, and wherein the second look-up table is different than the first look-up table;
• and
• encoding the current block using the determined quantization step size.
