Description
VMAF is a perceptual video quality assessment algorithm developed by Netflix. Refer to the FAQ page for frequently asked questions of VMAF.
This is a port of the VapourSynth plugin VMAF.
vmaf is used.
Requirements
- [x86] AviSynth+ or AviSynth 2.6
- [x64] AviSynth+
- Supported color formats: Y8, YV12, YV16, YV24, YV411
- AviSynth+: all planar Y and YUV formats (8/10/12/14/16bit) are supported.
NOTE:The folder model must be located in the same folder as VMAF.dll.
Syntax and Parameters
- VMAF (clip reference, clip distorted, int "model", string "log_path", int "log_fmt", bool "ssim", bool "ms_ssim", int "pool", bool "ci")
- clip =
- clip =
- Clips to calculate VMAF score. Must be in YUV 8..16-bit planar format.
- First input clip is the reference, second input clip is the distorted clip (e.g. processed, encoded, etc).
- clip =
- int model = 0
- Sets which model to use. Refer to the models page for more details.
- 0: vmaf_v0.6.1.pkl
- 1: vmaf_4k_v0.6.1.pkl
- Default: 0.
- Sets which model to use. Refer to the models page for more details.
- int model = 0
- string log_path =
- Sets the path of the log file.
- Default: None.
- string log_path =
- int log_fmt = 0
- Sets the format of the log file.
- 0: xml.
- 1: json.
- 2: csv.
- Default: 0.
- Sets the format of the log file.
- int log_fmt = 0
- bool ssim = false
- Whether to also calculate SSIM score.
- Default: False.
- bool ssim = false
- bool ms_ssim = false
- Whether to also calculate MS-SSIM score.
- Default: False.
- bool ms_ssim = false
- int pool = 1
- Sets the method to pool the per-frame scores.
- 0: Mean.
- 1: Harmonic mean.
- 2: Min.
- Default: 1.
- Sets the method to pool the per-frame scores.
- int pool = 1
- bool ci = false
- Whether to enable confidence interval.
- True: It uses vmaf_b_v0.6.3 for model=0 and vmaf_4k_rb_v0.6.2 for model=1.
- Refer to the VMAF confidence interval page for more details.
- Default: False.
- bool ci = false
Examples
Comparing a high quality clip vs an encoded clip:
VMAF(HQ_original, HQ_encoded, model=0, ssim=false, ms_ssim=false, pool=1, ci=false)
