There are thousands of filters but these are the ones that are most relevant to the majority of AMV editors. I have found that these work best for me and for most animes However, there are a lot of alternatives to a lot the ones listed below. You can substitute them with ones you might find work better for you.
AVISource This is used for Importing .AVI files regardless of bit depth. **DirectShowSource** This is used for importing .MOV, .MP4, .MKV, .MXF files in 8bit color depth. **LWLibavVideoSource** This is used for the same cases as DirectShowSource, but extends to higher bit-depths of footage such as 10bit or 12bit.
Used to convert the colorspace of your footage. You need to use this as certain filters only work in specific colorspaces.
**ConvertToYV12** Converts the colorspace of the imported footage to YV12. This is the colorspace that 95% of filters work in, so it's good to add this to your script every time regardless of what you're going to use.
Cleaning filters are used to remove noise, grain, banding or other kinds of unwanted video artifacts.
**GradFun3** Used for de-banding. The primary function used for de-banding anime is the threshold function (thr). The higher this setting, the more strength the de-banding effect has. The function limits are 0.0 to 10.0.
A good setting for most anime is 1.8. (eg. Gradfun3(thr=1.8)
Original Image, no-debanding script. Notice the blocks of color in the shadows and walls around the character.
Same frame with GradFun3(thr=1.5). Notice the shadows and walls are smoothed out and no longer have artifacts.
DeNoise is used for removing noise and grain. The default setting of Denoise() is good for most anime
Used to darken the outlines in a scene to aid with the sharpening process and make the characters stand out.
**Hysteria** Darkens outlines with a lot of variables and control over the strength of areas it affects.
Original Image
Image with Hysteria(strength=10, luma_cap=250) added. Notice the definition added to the outlines
Toon Darkens outlines but only has 1 function. Good for clean footage that doesn't need that much of a boost to the outlines.
Sharpening filters are used to sharpen or thin lines to give the appearance of sharpness
**Awarpsharp2** Thins and sharpens outlines by warping them. The only variable worth changing on the script preset for anime is the depth setting. It ranges from 0 - 64. 16 is usually a good starting point for most anime. It would be very rare to need to go above 24.
The higher your input resolution the higher you will have to raise the depth function to affect the image.
