== Description ==
[[FDecimate2]] is based on [[FDecimate]] v1.0.2. [[FDecimate2]], fixes some problems with bugged metrics in FDecimate v1.0.2 and also adds support for RGB32/24 and 8 bit v2.60 Planar colorspaces. 

The additional args added in FDecimate v1.1.0 is not supported, they apparently introduced problems into the plugin.

== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|FDecimate (clip, float "rate", float "threshold", bool "metrics", bool "show", bool "debug", bool "chroma")}}
<br>
::{{Par2| |clip| }}
:::Input clip.
<br>
::{{Par2|rate|float|23.976}}
:::This parameter sets the desired output frame rate. Frames will be removed from the video to achieve this frame rate while keeping audio and video in sync. 
<br>
::{{Par2|threshold|int|1.0}}
:::This parameter sets the threshold difference metric for duplicate detection. If the difference metric between two frames exceeds this threshold, the two frames are considered to be different frames. i.e., not duplicates. Refer to the "How to Use FDecimate()" section above for an explanation of how to set this threshold properly.
<br>
::{{Par2|metrics|bool|false}}
:::This parameter is used to determine the proper threshold to use for duplicate detection. When it is set to true, no decimation occurs and the difference metric for each frame is shown overlaid on the video and in the DebugView output. Refer to the "How to Use FDecimate()" section above for an explanation of how to use this parameter to set the threshold properly.
<br>
::{{Par2|show|bool|false}}
:::This parameter enables information to be displayed on the frame. It also displays the software version.
:::The meanings of the numbers are as follows:
:::*blind: The choice that would be made using naive decimation, not trying to avoid delivering duplicates.
:::*choose: The choice that would be made when trying to avoid duplicates.
:::*use: The final ch
<br>
::{{Par2|debug|bool|false}}
:::This parameter enables information to be printed via OutputDebugString(). A utility called DebugView is available for catching these strings. The information displayed is the same as shown by the show option above.
<br>
::{{Par2|chroma|bool|true}}
:::If false, will not scan chroma when differencing YUV frames.
