limitUV can usually be safely set to higher values than limitY.DeGrainMedian can be stacked twice to good effect if the limits are low enough.DeGrainMedian should be applied before other denoisers.interlaced (true/false) should be set to true if your source is interlaced.The higher you set mode, the higher you can usually safely set limitY and mode (0-5) determines the filter's operation mode all you need to know about it is that higher values will.limitUV (0-255) determines the maximum amount by which DeGrainMedian may change a pixel's chroma value.Įverything just said about limitY also applies here.The strength of the denoising (but going too high may cause overblurring). Would have been changed by more than this value, it is changed by exactly this value instead. limitY (0-255) determines the maximum amount by which DeGrainMedian may change a pixel's luma value.Meant ostensibly for grain removal but also useful for general denoising.ĭefaults: DeGrainMedian(limitY=4, limitUV=6, mode=1, interlaced=false) And then you've got spatio-temporal denoisers, which are basically a little from Column A and a little fromĬolumn B: they do denoising/smoothing across both time AND space (therefore 3 dimensions). Then you've got your temporal smoothers, which smooth out differences between pixels in different frames (smoothingĪcross time). So, you've got your spatial smoothers, which denoise/smooth among the pixels in individual frames (smoothing across the Scintilla's Guide to AVISynth Postprocessing Filters: Spatio-Temporal Smoothers Scintilla's Guide to AVISynth Postprocessing Filters: Spatio-Temporal Smoothers
