Allow to add fixed quantization parameter offset between luma and
chroma quantization parameters. This control directly corresponds
to the chroma_qp_index_offset field of the h.264 picture parameter
set.

This string is too long. The one above it ("H264 Set QP Value for HC Layers") has exactly 31
characters, which is the maximum. Perhaps abbreviating "Prediction" by "Pred" will work.
