[BUG] Unexpected behaviour x264 and max qp
#2
You are correct.
Max quant should be initialized with a maximum of 69.
Since it's calculated this way: QP_MAX = 6*(CALULCATION_BIT_DEPTH-8) +15 + 18;
So for 8 bit it's 69. Not that the maximum value used for qp and crf is still 51. (since the +18 are 'virtual')
-> the initial values Hybrid uses as default will still be 1-51, but the initial maximum for the quantizer change should be 69.
