gblur a gausian based blur plugin for the sequence editor
float capable blur for blender versions 2.43+
source:gblur.c linux: gblur.so
This plugin makes a blur filter based on a gaussian curve.
The buttons:
gblur:turns the plugin on or off
blur & vert blur: The
float value blur factors in this plugin gives you access to a much
better range of blur settings, especially at smaller blur values. max radius & max v radius: You can set the radius of the filter kernal below the blur value if you are either trying to speed up larger blurs or you want to flatten the filter curve. It's best to leave this value high and use the optimise button
sep h-v: This allows you to have a different blur factor for the vertical blur.
info /TMI:This prints plugin information to the console window. toggling this button to yellow and you will get (possibly) Too Much Info...including a full printout of the filter values:

No floatbuffers present...this plugin uses float values->converting
blur settings...blur= 1.153...radius= 10...kernal size: 21
optimizing filter kernal from 21 to 5
pixel distance -2: 0.036% influence...subtotal= 0.036%
pixel distance -1: 11.374% influence...subtotal= 11.410%
pixel distance 0: 77.180% influence...subtotal= 88.590%
pixel distance 1: 11.374% influence...subtotal= 99.964%
pixel distance 2: 0.036% influence...subtotal= 100.000%
converting back to char values...done
NOTE: although info/TMI is useful for setting up the plugin, printing the info to the console can really slow the plugin down... turn it off before you actually process your strip!
ipo blur & ipo rad: These buttons will multiply the blur and radius settings by the ipo value for animated blurs.
optimise:If you toggle optimise on(default), the radius setting for small blurs will have the kernal automatically clipped to the minimum size to produce the best quality blur...bigger kernals will just slow the plugin.
If you want an automatic best gaussian blur, just put the max radius at 50 and hit optimize...(hit TMI and just watch how fast the radius and kernal sizes grow as you increase the blur...and how much slower the plugin is).
