Hello,
What does this additional option do for QuickSync encoder?
Is it a lower power than standard? Less performant? Both are hardware accelerated, aren't they?

Re: [Nightly] Low Power QuickSync Hardware encoder
I don't know all the details, but I'm pretty sure it's "low power" as in power == electricity…
Re: [Nightly] Low Power QuickSync Hardware encoder
I'm pretty sure it's an optimization for the low power Intel CPUs, such as my 65W i5 8250.
It runs about the same benchmarks as an i7 4th Gen, but with less consumption under load.

Re: [Nightly] Low Power QuickSync Hardware encoder
low power means fixed function, so it only uses the fixed function unit for encoding which uses less power. Without FF/lower power it's a hybrid, it can use some GPU resources like execution units, in this mode there is more flexibility/quality but also uses more power.
Up to Gen9 graphics (Skylake-Cometlake) Intel only supports Hybrid for h265 encoding, Gen11 (Icelake) is Intels first fully FF h265 solution but didn't support bframes+bpyramid. Iris Xe (Tigerlake) fixed function added bframes+bpyramid.
