    183183The film grain synthesis feature is invoked with `-svtav1-params film-grain=X`, where X is an integer from 1 to 50. Higher numbers correspond to higher levels of denoising for the grain synthesis process and thus a higher amount of grain.

     185The grain denoising process can remove detail as well, especially at the high values that are required to preserve the look of very grainy films. This can be mitigated with the `film-grain-denoise=0` option, passed via `svtav1-params`. While by default the denoised frames are passed on to be encoded as the final pictures (`film-grain-denoise=1`), turning this off will lead to the original frames to be used instead.
