Description

A simple plugin that calculates a weighted frame-by-frame average from multiple clips. This is a modern rewrite of the old Average plugin but a bit faster, additional colorspace support, and some additional sanity checks.

  • The usage is identical to the old Average plugin or RedAverage: Average (clip1, weight1, clip2, weight2, clip3, weight3, ...)
  • Output pixel value is calculated as: out[x] = clip1[x] * weight1 + clip2[x] * weight2 + clip3[x] * weight3...


Requirements


*** vcredist_x86.exe is required for Average-x86
*** vcredist_x64.exe is required for Average-x64


Syntax and Parameters

Average (clip, float, clip, float, clip, float ...)


clip   =
Input clip 1 / 2 / 3 ...
float   =
Weight 1 / 2 / 3 ...


You can average as many clips as you want but there are a few limitations.

  • Average requires an even number of arguments.
  • All clips must have the same colorspace.
  • All clips must have identical width and height.
  • All clips must have the same or greater number of frames as the first input clip.
  • Best performance when absolute values of all weights are smaller or equal to one.

Average for AviSynth 2.5

This is the original Average plugin written by mg262. It works with AviSynth 2.5/2.6 but only supports the YV12 colorspace. Additional information in the following links.
