The chroma value determines the color space used for encoding. By default, the chroma value is set to 4:2:0, which provides a good balance between image quality and network bandwidth. You can increase the default chroma value to 4:4:4 to improve image quality. You don't need to use GPU acceleration to change the default chroma value.
