    I have been upscaling for about two weeks

    I would like to use AviSynth+, AVSPMod and ffmpeg to restore and upscale some old TV SD shows (BW Telerecordings)
    So far my script is as follows:

    SetFilterMTMode ("QTGMC", 2)
    FFmpegSource2("test.mkv", atrack=1)
    ConvertToYV12()
    AssumeTFF()
    QTGMC(preset="Slow", EdiThreads=1)
    Spline64Resize(1440,1080)
    Prefetch(1)

    ffmpeg -i "test.avs" -c:v prores -profile:v 3 -pix_fmt yuv422p10le -c:a pcm_s16le "output.mov" as the batch

    Many of these old shows were shot on 405 line video and the transfer to 16mm has added unnatural grain that when the image is in motion looks awful.

    Please could you tell me the best plugin/filter to add to AVISynth+ and the script that would remove some temporal and spatial grain but not kill detail? At which point in the a script would I insert the line(s)?


    Thank you in advance.

    That's why a sample was requested and why so many were listed. Or you can do your own experimenting.

    Try TemporalDegrain2, you'll find some tips in the script.

  9. Whenever i deal with BW i use grayscale() filter, this filter out chroma noise the simplest way possible (I don't need u chroma >>> out my way). I know what some purist will say...
    When dealing with BW it's always interesting to work on the whole luma range (get good shadows,blacks, whites with a filter like gcurves (virtualdub) or similar. Food 4 thought
