I have used the bicubic filter to do the up/down scaling. Here is a simple one-liner that uses the filter_complex to do the resolution change and then computes the VMAF value. However, in case the source and destination videos are not of the same resolution, then you have to ensure that the destination is brought to the same resolution as the source video before computing VMAF. ffmpeg.exe -i videoToCompare.mp4 -i originalVideo.mp4 -lavfi libvmaf="model_path=vmaf_v0.6.1.pkl":log_path=vmaf_logfile.txt -f null. If your source and destination videos are of the same dimensions (height and width), then you can directly compute the VMAF value using the command line below.Īll you need to do is point FFmpeg to the location of the VMAF model file and it will do the rest. Let’s look at a couple of ways of computing VMAF.
To understand how to install VMAF, please read our “ VMAF Installation” article. It’s become very popular as it succeeds (not fully) at automating subjective quality testing that usually requires humans to watch and score videos.įFmpeg and Netflix’s VMAF are now part of every video processing and compression engineer’s toolbox. VMAF from Netflix stands for Video Multi-method Assessment Fusion, and it is a video quality metric that combines human vision modeling with machine learning.
