# I'm using -rc:v vbr -cq:v 20 (higher = more compression) to have a variable
# bit-rate with a quality target. This gives us a good looking re-encoding that
# does a good job preserving the quality of the source video (at least for
# twitch streams I'm trimming) but the bitrate might be higher or lower than
# the source. The quality metric will fluctuate during encoding because NVENC
# does't use a fixed quantization parameter. -cq:v is a target, not a constraint.
# So you can have quite the fluctuating (or high) bitrate with these two params.
# In order to set a birate cap that is prioritized over visual fidelity, we can
# add in:
# -maxrate:v -bufsize:v
# (with bufsize typically being double the maxrate)
#
# Using this with the vbr and crf params tells the NVENC encoder to try to
# encode at a perceptual quality level around CQ=20 but keep the bitrate under
# 6000 kbps (constrained VBR). If a scene is too complex to maintain CQ=20
# within the bitrate cap, the encoder will:
# * Raise the quantizer (lower quality) to obey the -maxrate
# * Result: CQ metric fluctuates upward
