|'''FadeIn'''
|blends progressively ''from'' {{FuncArg|color}} at the beginning.
|-
|'''FadeOut'''
|blends progressively ''to'' {{FuncArg|color}} at the end.
|-
|'''FadeIO'''
|blends progressively from/to {{FuncArg|color}} at ''both'' ends.

<div style="max-width:68em" >
*The sound track (if present) also fades linearly to and/or from silence.  

*The fading affects only the first/last {{FuncArg|num_frames}} frames of the video. 
{{HalfBreak}}
*The first/last frame of the video becomes almost-but-not-quite {{FuncArg|color}}. 
<div {{ListItemContinue}}>
An additional {{FuncArg|color}} frame is added at the start/end, thus increasing the total frame count by one (or for '''FadeIO''', by two).
</div>
{{HalfBreak}}
*'''FadeIn'''{{BoldColor|blue|100|0}} / '''FadeOut'''{{BoldColor|blue|100|0}} / '''FadeIO'''{{BoldColor|blue|100|0}} do not add the extra {{FuncArg|color}} frames, leaving the end(s) almost-but-not-quite {{FuncArg|color}}.

*'''FadeIn'''{{BoldColor|blue|100|2}} / '''FadeOut'''{{BoldColor|blue|100|2}} / '''FadeIO'''{{BoldColor|blue|100|2}} add ''two'' extra {{FuncArg|color}} frames at the start/end instead of one.

:{{Par2|clip|clip|}}
::Source clip; all AviSynth [[Convert|color formats]] accepted.

:{{Par2|num_frames|int|}}
::Fade duration.

:{{Par2|color|int|$000000}}
::Specifies the start/end color; black by default. 
::*See [[Color_presets|Color presets]] for preset (named) colors. 
::*See [[Colors]] for more information on specifying colors numerically.

:{{Par2|fps|float|24.0}}
::Provides a reference for {{FuncArg|num_frames}} in audio only clips. It is ignored if a video stream is present.
::*Set {{FuncArg|fps}}=[[Clip_properties|AudioRate]] if sample exact audio positioning is required.

== Notes ==
<div {{BoxWidthIndent|48|0}} >
 FadeOut(clip, {{FuncArg|num_frames}})
</div>
is just a shorthand for 
<div {{BoxWidthIndent|48|0}} >
 [[Dissolve]](clip, [[BlankClip]](clip, {{FuncArg|num_frames}}+1, color={{FuncArg|color}}), {{FuncArg|num_frames}})
</div>
(with num_frames+'''2''' instead of num_frames+'''1''' for <tt>FadeOut2</tt>, and num_frames+'''0''' for <tt>FadeOut0</tt>).


== Changes ==
<div style="max-width:56em" >
{| border="1"
|- 
| v2.56
| FadeIn0/FadeIO0 /FadeOut0 commands are added and the fps parameter is added to all fade functions.
|- 
| v2.07
| Added FadeIO/FadeIO2 commands. Added color parameter to all fade functions.
|- 
| v2.06
| Till v2.06 the FadeIn/FadeIn2 commands do not exist, but you can get the same effect by reversing the arguments to Dissolve: Dissolve(Blackness(''clip, n+1'', color=''color''), ''clip, n'').
