Motion Wind Ino\medskip

\par

\normalsize

Allow to add wind flow lines to the image.

\par

It uses an art drawing method, usually seen in animation, to represent a fast motion.\par

Adds the effect of fast motion to the brightest pixels of the image.\\

\\

-{-}- \ Inputs \ -{-}-\\

Source\par

Connect the image to be processed.\\

\\

Reference\par

Connect the reference image to assign the strength of the effect into each pixel.\\

\\

-{-}- \ Settings \ -{-}-\\

Direction\par

Specify the direction of the motion lines.\par

Options available are: Right, Up, Left, Down.\par

The default setting is Right.\par

Direction is fixed for the default orientation of the image. If the column/layer is\par 

rotated, motion lines will rotate with it.\\

\\

Dark\par

When inactive motion lines will spread from brightest parts of the image.\par

When active motion lines will spread from darkest parts of the image..\par

The default setting is inactive.\\

\\

Alpha Rendering\par

This option is valid only when there is an Alpha channel.\par

When inactive, it masks the changes in the RGB values using the original Alpha\par 

of the image.\par

When active, the effect will be able to modify the Alpha channel, extending it\par 

as necessary to reproduce the full span of the effect.\par

The default setting is ON.\\

\\

Length Min\\

Length Max\par

Specify the length of the motion lines.\par

The unit is millimeters.\par

Specify a value in the range from 0 to 1000.\par

Decimal places are also taken into account, for subtle changes in the length.\par

If Min and Max are different, the lenght of each motion line will be random, between\par 

those values.

\newpage

\thispagestyle{empty}

\ \vspace{-0.2em}

\par

When Min and Max are the same, all motion lines will have the same lenght.\par

The default value for Min is 0, and Max is 8.573.\par

-{-}> See \textquotedbl Figure 1:\ \ Length Wind\textquotedbl \ .\par

-{-}> See \textquotedbl Figure 4:\ \ Force is 1 and Density is 1\textquotedbl \ .\par

-{-}> See \textquotedbl Figure 7:\ \ Length Wind and Force is 10\textquotedbl \ .\\

\\

Length Bias\par

Allows to introduce a deviation in the random pattern of the length.\par

Using values between 0.1 and 1.0, will make prevail shorter lines.\par

Using a value of 1.0, the pattern will be uniform.\par

Using values between 1.0 and 10.0, will make prevail longer lines.\par

The default value is 1.\par

-{-}> See \textquotedbl Figure 1:\ \ Length Wind\textquotedbl \ .\\

\\

Length Seed\par

This seed controls the random pattern for the length.\par

Specify an integer value greater than or equal to 0.\par

If the same value is given to the same image, it will produce the same pattern.\par

Changing the value will produce different patterns.\par

For example, if you want an ever changing pattern of lines from a single image,\par

you can animate the seed value on a frame by frame basis.\par

The default value is set to 1.\\

\\

Force Min\\

Force Max\par

Allows to define the decay rate of the motion lines.\par

Values between 0.1 and 1.0, will cause a fast decay rate,\par

A value of 1.0 will produce a linear decay rate,\par

Values between 1.0 and 10.0, will cause a slow decay rate,\par

If Min and Max are different, the decay rate of each motion line will be random,\par 

between those values.\par

When Min and Max are the same, all motion lines will have the same decay rate.\par

The default value is 1 for both.\par

-{-}> See \textquotedbl Figure 2:\ \ Force Wind\textquotedbl \ .\par

-{-}> See \textquotedbl Figure 5:\ \ Force is 0.1\textquotedbl \ .\par

-{-}> See \textquotedbl Figure 7:\ \ Length Wind and Force is 10\textquotedbl \ .\\

\\

Force Bias\par

Allows to introduce a deviation in the random pattern of decay.\par

Using values between 0.1 and 1.0, will make a strong decay prevail.\par

Using a value of 1.0, the decay pattern will be uniform.\par

Using values between 1.0 and 10.0, will make a weak decay prevail.\par

The default value is 1.\par

-{-}> See \textquotedbl Figure 2:\ \ Force Wind\textquotedbl \ .\\

\\

Force Seed\par

This seed controls the random pattern for the decay rate.\par

The options are similar to \textquotedbl Length Seed\textquotedbl .\\

\\

Density Min\\

Density Max\par

Allows to define the density of the motion lines.\par

If it is 0, there will be no motion lines effect.\par

Values between 0 and 1.0 will produce low densities.\par

A value of 1.0 will produce a standard density.\par

Values greater than 1.0 will produce high densities. The maximum value is 100.\par

If Min and Max are different, density will be random between those values.\par 

When Min and Max are the same, density will be uniform.\par 

The default value is 1 for both.\par

-{-}> See \textquotedbl Figure 3:\ \ Density Wind\textquotedbl \ .\par

-{-}> See \textquotedbl Figure 6:\ \ Density is 0.2\textquotedbl \ .\\

\\

Density Bias\par

Allows to introduce a deviation in the random pattern of density.\par

Using values between 0.1 and 1.0, will make lower densities prevail.\par

Using a value of 1.0, the density pattern will be uniform.\par

Using values between 1.0 and 10.0, will make higher densities prevail..\par

The default value is 1.\par

-{-}> See \textquotedbl Figure 3:\ \ Density Wind\textquotedbl \ .\\

\\

Density Seed\par

This seed controls the random pattern for the density.\par

The options are similar to \textquotedbl Length Seed\textquotedbl .\\

\newpage

\thispagestyle{empty}

\ \vspace{-0.2em}

\\

In order to achieve a uniform lines effect:\par

The same values should be assigned to \textquotedbl Length Min\textquotedbl \ and \textquotedbl Length Max\textquotedbl ,\par

\textquotedbl Force Min\textquotedbl \ and \textquotedbl Force Max\textquotedbl ,

\textquotedbl Density Min\textquotedbl \ and \textquotedbl Density Max\textquotedbl \ parameters,\par 

to produce uniform lines.\\

\\

To synchronize random patterns:\par

If \textquotedbl Length Seed\textquotedbl , \textquotedbl Force Seed\textquotedbl , and \textquotedbl Density Seed\textquotedbl \ are set to the same value\par 

at the same frame, its patterns will match, and it will become stronger and\par 

weaker at the same time.\par

Using different values will produce different patterns for each parameter.\\

\\

To fix a random pattern when the camera is moving:\par

When moving the camera over a background image, the random pattern changes\par 

on each frame according to the change of the picture.\par

To fix the pattern the entire backgroung image must be processed.\\

-{-}-{-}-{-}\\

\\

Length Ref\par

When inactive there will be no reference image driving the Length.\par

When active, the image connected to the Reference port will drive the Length.\par

The values of the selected channel in the Reference parameter, will drive the Length.\par

If no reference image is available, the length will be determined by the Source image\par 

brightness.\par

The darker the pixel where lines begin, the shorter they will be.\par

As the whole image tone is lowered, please adjust the Min and Max Length values.\par

The default state is inactive.\\

\\

Force Ref\par

When inactive there will be no reference image driving the Force.\par

When active, the image connected to the Reference port will drive the Force.\par

The values of the selected channel in the Reference parameter, will drive the Force.\par

If no reference image is available, the force will be determined by the Source image\par 

brightness.\par

The darker the pixel where lines begin, the weaker they will be.\par

As the whole image tone is lowered, please adjust the Min and Max Force values.\par

The default state is inactive.\\

Density Ref\par

The values of the selected channel in the Reference parameter, will drive the\par 

Density.\par

If no reference image is available, the density will be determined by the Source\par 

image brightness.\par

The darker the pixel where lines begin, the thinner they will be.\par

As the whole image tone is lowered, please adjust the Min and Max Density values.\par

The default state is inactive.\\

\\

Reference\par

Choose how the Reference image values are used to set the strength of the effect\par 

into each pixel.\par

Choose from Red/Green/Blue/Alpha/Luminance.\par

Choose Nothing to disable the effect.\par

The default value is Red.
