How to determine the level of film grain synth on a video? (lemmy.ml)

Does anyone know how to determine the level of grain synth used in an encoded video? I have .webms that I've encoded with ffmpeg and svt-av1 but I don't have that grain synth information anymore.

In fact it would be nice if I could just see any other information about an encoded video (rate factor, preset used, etc). These details don't appear when using mediainfo so I presume they are lost and unknowable. But grain synth occurs at decode time, so that should still be something I can figure out, right?

I don't know the answer to the grain synth question, but I am fairly sure you can't recover encoder settings from the default bitstream metadata without adding tags like x26[4|5] do
