  "message": "Turn on frame_sign_bias by default.\n\nThis experiment of frame_sign_bias is to remove the 7 bits in the\nframe header that signal the sign bias value for the 7 reference\nframes. Instead of explicit signaling, this experiment is to use\nthe frame_offset value to derive the frame sign bias. It achieves\n-0.08~-0.1% coding gain on average. It has been adopted by AOM.\n\nChange-Id: I543f2641d9a11cabfe822cd4daa8b88b938421d6\n",
