== Description ==
:One of the fundamental properties of noise is that it's random. One of the fundamental properties of motion is that it's not.
:This is the premise behind FluxSmooth, which examines each pixel and compares it to the corresponding pixel in the previous and last frame.
:Smoothing occurs if both the previous frame's value and the next frame's value are greater, or if both are less, than the value in the current frame.

:I like to call this a "fluctuating" pixel, then I like to wipe that pixel from existence by averaging it with its neighbours.
:For FluxSmoothST, this is (by default) done in a spatio-temporal manner, in that for each fluctuating pixel its 8 immediate spatial neighbours
:as well as its 2 temporal neighbours (the above mentioned corresponding pixel from the previous and next frames) are considered for inclusion in the average.
:If the value of each pixel is within the specified threshold, it is included. If not, it isn't. FluxSmoothT performs only temporal averaging.
 
== Requirements ==

:- [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|Progressive]] input only

Version Date Changes 
v1.1b 2006/11/09 - Changes by tritical.
- Fixed assuming previous and next frame pitches were the same as the current frame pitch. 
v1.1a 2004/07/29 - Yet another "oops" release.
- Current pixel is once again considered in the averaging code -- I found the lack of it too aggressive,
especially during fast motion.
- Also fixed stupid "3am bug" involving a couple of variables I'd declared static that shouldn't have been.
- Thanks to krieger2005 for spotting that one, and ARDA for diagnosing it. 
v1.1 2003/07/26 - Changed the averaging code so that the current pixel is excluded, which produces better noise reduction.
- Also split the code into two different filters, FluxSmoothT and FluxSmoothST.
- FluxSmoothT does temporal-only smoothing (equivalent to setting "spatial_threshold=-1" in FluxSmoothST)
and is about 50% faster.
- Removed Avisynth 2.0x version to tidy up the code base. Does anyone actually use it any more?
- My thanks to fabrice and sh0dan for the 1.01 release during my extended absence :). 
v1.01 2003/??/?? - Added by sh0dan:
- Removed leak in AviSynth 2.5 YV12 mode (code by fabrice)
- Aligned tables and variables.
- Use AviSynth BitBlt for copying chroma.
- Don't use streaming store. (movntq)
- All in all an approximate 15% speedup compared to previous version.
- All changes are marked with "sh0:". 
v1.0 2003/01/08 - First "stable" release.
I think it's been tested enough, but wait for a bunch of bugs to emerge and make me a liar...
- Fixed a bug that, in conjunction with a bug in the built-in resizers, caused an access violation
under certain circumstances. Thanks to sh0dan for spotting that one :).
- Added "SetCacheHints" and upgraded to "AvisynthPluginInit2" in 2.5 version. 
v0.4 2002/12/16 - Implemented iSSE-optimized version, which runs roughly double the speed of the C++ version.
- Some small optimizations to C++ version.
- Now smooths chroma as well as luma. 
v0.3 2002/11/19 - Fixed bad bug that caused incorrect smoothing: no more in-place filtering.
- Changed defaults back to what they were, now that the algorithm works correctly.
- Spent some time benchmarking and tweaking various pieces of code, so should now be significantly faster. 
v0.2 2002/11/16 - Fixed non-fatal bug that caused a request for one frame beyond the end of the clip.
- Changed to in-place filtering so could squeeze a few optimizations here and there.
- Changed too-high defaults.
- First AviSynth 2.5/YV12 release. 
v0.1 2002/11/16 - First release; alpha code.
