# AverageFrames

std.AverageFrames(vnode[] clips, float[] weights[, float scale, bint scenechange, int[] planes])

  AverageFrames has two main modes depending on whether one or multiple clips are supplied. The filter is named AverageFrames since using ones for weights is an easy way to average many frames together but it can also be seen as a temporal or multiple frame convolution.

  If multiple clips are supplied then the frames from each of the clips are multiplied by the respective weights, summed together and divided by scale before being output. Note that only integer weights and scale are allowed for integer input formats.

  If a single clip is supplied then an odd number of weights are needed and they will instead be temporally centered on the current frame of the clip. The rest works as multiple clip mode with the only difference being that scenechange can be set to avoid averaging frames over scene changes. If this happens then all the weights beyond a scene change are instead applied to the frame right before it.

  At most 31 weights can be supplied.
