VideoToolbox compression quality

Post by adrienj » Sun Dec 30, 2018 8:26 pm

Description of problem or question:
Now, HandBrake 1.2.0 uses VideoToolbox for hardware-accelerated video encoding and decoding capabilities.
When I select H264 (VideoToolbox) or H265 (VideoToolbox), it's not possible to choose a constant quality, but only an average birate.
Is this a limitation of VideoToolbox?

HandBrake version:

Operating system and version:
macOS 10.13.6 High Sierra
