In other words, it is not possible to build one FFmpeg with multiple versions of x264 with different bit depths. The researchers found that the used AV1 encoder was operating at a speed "2500–3500 times lower than competitors", while admitting that it has not been optimized yet. Intel will continue to improve quality and speed, targeting 4K and 60 frames per second standards for 10-bit content. I think the AV1 bitstream will be frozen soon, so when AV1 support gets added into ffmpeg and Ren'Py, AV1 codec will be used instead.
