[edit] Description
Fast approximate Gaussian blurs.
[edit] Requirements
- [x86]: AviSynth+ or AviSynth 2.6
- [x64]: AviSynth+
- Supported color formats: RGB24, RGB32, Y8, YV12, YV16, YV24, YV411
[edit] Syntax and Parameters
- FastBlur (clip, float blur, float "y_blur", int "iterations, bool "dither", bool "gamma", float "threads")
- clip =
- Input clip.
- clip =
- float =
- Blur radius (equivalent to Photoshop Gaussian Blur's radius).
- float =
- float yblur =
- Vertical blur (if different from horizontal blur)
- float yblur =
- int iterations = 3
- Number of iterations for approximation. Defaults to 3. A value of 1 performs a box blur.
- int iterations = 3
- bool dither = false
- Enable/disable dithering.
- bool dither = false
- bool gamma = true
- Approximate gamma awareness. This should be disabled for masks.
- bool gamma = true
- float threads = -1
- Now has a threads parameter to set the number of threads. Defaults to half the number of logical processors minus 1, or 2, whichever is greater (unless you only have one logical processor, in which case: 1).
- Set threads to 0 to use all available logical processors, or use a floating pointer between 0 and 1 as a multiplier on the number of local processors, e.g. to use 3/4 of them, set threads to 0.75. [1]
- < 0 : automatic
- 0 : use as many threads as logical processors
- < 1 : use floor(logical processors*threads) threads
- >= 1 : use floor(threads) threads
- float threads = -1
[edit] Examples
- FastBlur with strong settings:
AviSource("blah.avi") #FastBlur(..TODO..)
