Autodeinterlace is disabled when setting this -subsample N Specifies the subsampling of frames to speed up calculation.

fps FPS Video Frame Rate: force frame rate conversion to value. Time in seconds from the beginning of the Reference video to which the Sync Window will be applied from. The sync lookup will be done between the first frames of the Distorted input and this Subsample of the Reference. The sync is doing by a frame-by-frame look up of the best PSNR See for more options of syncing As output, a json file with VMAF score is created optional arguments: -h, -help show this help message and exit -sw SW Sync Window: window size in seconds of a subsample of the Reference video. It allows to deinterlace, scale and sync Ref and Distorted video samples automatically: Autodeinterlace: If the Reference or Distorted samples are interlaced, deinterlacing is applied Autoscale: Reference and Distorted samples are scaled automatically to 1920x1080 or 3840x2160 depending on the VMAF model to use Autosync: The first frames of the distorted video are used as reference to a sync look up with the Reference video. $ python3 easyVmaf.py usage: easyVmaf -d D -r R Script to easy compute VMAF using FFmpeg.

Just clone the repo and run it from the source folder.

'HD Neg' and 'HD phone' models are computed by defaultįFmpeg >= 5.0 build with libvmaf. For using easyVmaf with FFmpeg = v5.0.ĭocker image - better handling of dependencies and built instruccions Since easyVmaf 2.0 only FFmpeg versions >= 5.0 will be supported.

Python tool based on ffmpeg and ffprobe to deal with the video preprocesing required for VMAF inputs:ĭetails about How it Works can be found here.
