.TP
.B brd_scale=<0\-10>
Downscales frames for dynamic B-frame decision (default: 0).
Speed should increase by a factor of 4 every time brd_scale is increased
by 1.
Each time brd_scale is increased by one, the frame dimensions are
divided by two, which improves speed by a factor of four.
Both dimensions of the fully downscaled frame must be even numbers, so
brd_scale=1 requires the original dimensions to be multiples of four,
brd_scale=2 requires multiples of eight, etc.
In other words, the dimensions of the original frame must both be
divisible by 2^(brd_scale+1) with no remainder.
