  • SVT-AV1

  • This is the default film grain modeling process: https://gitlab.com/AOMediaCodec/SVT-AV1/-/raw/master/Docs/img/film_grain_fig1.png

  • FFMetrics

    Visualizes Video Quality Metrics (PSNR, SSIM & VMAF) calculated by ffmpeg.exe

  • Someone tried your suggestions and apparently, at least with the current FFmpeg versions, the flag doesn't affect VMAF (see here). I can only conclude VMAF does already return the highest values possible with AV1 as is, though what you said made a lot of sense so am unsure where exactly something changed from you gaining your knowledge to the current state of VMAF in FFmpeg (I'm a little puzzled).

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
