--target-quality <TARGET_QUALITY>
Target a VMAF score for encoding (disabled by default)
For each chunk, target quality uses an algorithm to find the quantizer/crf needed to
achieve a certain VMAF score. Target quality mode is much slower than normal encoding,
but can improve the consistency of quality in some cases.
The VMAF score range is 0-100 (where 0 is the worst quality, and 100 is the best).
Floating-point values are allowed.
--probes <PROBES>
Maximum number of probes allowed for target quality
[default: 4]
--probing-rate <PROBING_RATE>
Framerate for probes, 1 - original
[default: 1]
--probe-slow
Use encoding settings for probes specified by --video-params rather than faster, less
accurate settings
Note that this always performs encoding in one-pass mode, regardless of --passes.
--min-q <MIN_Q>
Lower bound for target quality Q-search early exit
If min_q is tested and the probe's VMAF score is lower than target_quality, the Q-search
early exits and min_q is used for the chunk.
If not specified, the default value is used (chosen per encoder).
--max-q <MAX_Q>
Upper bound for target quality Q-search early exit
If max_q is tested and the probe's VMAF score is higher than target_quality, the Q-
search early exits and max_q is used for the chunk.
If not specified, the default value is used (chosen per encoder).
