Description
- Fast implementation of TurnLeft(), TurnRight() and Turn180() AviSynth functions. fturn180 rotates a clip 180 degress,
- fturnleft rotates 90 degrees counter clock wise, and fturnright rotates 90 degrees clockwise. In addition, FTurn is
- internally multithreaded and is SSE2 and SSSE3 optimized, if your CPU supports SSSE3 you can assume a slightly better performance.
Requirements
- - AviSynth 2.5.8 or AviSynth 2.6.0 Alpha5 or greater
- - Progressive input only
- - Supported color formats: Y8, YV12, YV24
- ** If you're using AviSynth 2.5.8, YV12 will be the only colorspace supported.
Syntax and Parameters
- fturn180 (clip, bool "chroma")
- fturnleft (clip, bool "chroma", bool "mt")
- fturnright (clip, bool "chroma", bool "mt")
- bool chroma = true
- When set to false chroma will not be processed.
- This isuseful when chroma processing is not needed (almost often in anti aliasing scripts).
- bool chroma = true
- bool mt = true
- FTurn is internally multithreaded; set to false to disable.
- Chroma is processed in a separate thread with mt=true (default).
- bool mt = true
Examples
fturnleft with default settings:
AviSource("Blah.avi") fturnleft(chroma=true, mt-true)
