In this way, in order to get VMAF properly synced, the computation should start with the Frame located at <T> seconds within the reference video (this is done by trim filter). I started using the "vmaf" app, and as I understand from the scarce command-line help, it comes with embedded models, which have analogue names to the models specified in the model/ directory. - Netflix/vmaf Features are individual inputs that (VMAF) models may use to fuse into a final quality metric score. "_float" is an indicator that the model uses the legacy floating-point features (see our recent effort for migrating into fixed-point features to speed up VMAF). For example: ref_path \ dis_path \ --model model/vmaf_4k_v0. Default value: "vmaf_v0. Something must be wrong on your side, but still good to know that the vapoursynth filter works. 1.

Instead i just parse the vmaf value from the executed ffmpeg output in a populate variables processor by applying a regex. Select a reference video, a distorted video, and a VMAF model to get started. That means you'll introduce I have an ffmpeg version built with VMAF library. To compute the VMAF, I use this FFmpeg command : ffmpeg -hide_banner -i distorted. 'enable_transform' Use the --vmaf-model-path option to set the path to a different VMAF model file. ffmpeg crashes if the model file has DOS line endings. The above example considers that by computing the PSNR through a sliding window in the main video, the best value was finding at T seconds from the start of the reference video. As I write this, this must be either the default model (vmaf_v0. FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. mode=lf before cloning.
