Description
VapourSource is a VapourSynth script reader for AviSynth+ / AviSynth 2.6.
Requirements
- [x86]: AviSynth+ or AviSynth 2.6
- [x64]: AviSynth+
- VapourSynth R32 or greater (x86 or x64)
- SSE2 capable CPU
- Microsoft Visual C++ 2019 Redistributable Package (x86 / x64)
- *** vcredist_x86.exe is required for VapourSource-x86
- *** vcredist_x64.exe is required for VapourSource-x64
Supported Formats
VapourSource supports the following formats:
- VapourSynth colorspace - AviSynth colorspace - AviSynth+ colorspace - RGB24 - RGB24 - RGB24 - COMPATBGR32 - RGB32 - RGB32 - COMPATYUY2 - YUY2 - YUY2 - GRAY8 - Y8 - Y8 - GRAY16/H - Y8 (x2 width) - Y16 - GRAYS - Y8 (x4 width) - Y32 - YUV420P8 - YV12 - YV12 - YUV420P9/10/16 - YV12 (x2 width) - YUV420P16 - YUV422P8 - YV16 - YV16 - YUV422P9/10/16 - YV16 (x2 width) - YUV422P16 - YUV444P8 - YV24 - YV24 - YUV444P9/10/16 - YV24 (x2 width) - YUV444P16 - YUV444PS - YV24 (x4 width) - YUV444PS - YUV411P8 - YV411 - YV411 - Only constant format/resolution/framerate clips are supported. - *Y8/YV12/16/24 allow bit depths >8 using the 16bit interleaved format. 
Syntax and Parameters
VSImport
Imports an external VapourSynth script (*.vpy).
- VSImport (string source, bool "stacked", int "index", int "prefetch")
- string  source =   
 - Path to VapourSynth script (*.vpy); path can be omitted if the script is in the same folder as the AviSynth script (*.avs).
 
 
- string  source =   
- bool  stacked = false 
 - If this is set to true, MSB/LSB will be separated and be stacked vertically (Stack16).
 
 
- bool  stacked = false 
- int  index = 0 
 - Index of input clip.
 
 
- int  index = 0 
- int  prefetch = 0 
 - Request given amount of frames in advance (MT behaviour). If you have 4 physical cores, set it to 4.
- If AviSynth part of script is too easy in comparison with VS one, It might be good idea to set prefetch to 5. Anyway you can tune it and seek for better performance.
 
 
- int  prefetch = 0 
VSEval
Evaluates a VapourSynth script inside an AviSynth script, no need for an external script.
- VSEval (string source, bool "stacked", int "index", bool "utf8", int "prefetch")
- string  source =   
 - VapourSynth script to be evaluated.
 
 
- string  source =   
- bool  stacked = false 
 - If this is set to true, MSB/LSB will be separated and be stacked vertically.
 
 
- bool  stacked = false 
- int  index = 0 
 - Index of input clip.
 
 
- int  index = 0 
- bool  utf8 = false 
 - If this is set to true, source is assumed to be UTF-8 encoded (default: false).
 
 
- bool  utf8 = false 
- int  prefetch = 0 
 - Request given amount of frames in advance (MT behaviour). If you have 4 physical cores, set it to 4.
- If AviSynth part of script is too easy in comparison with VS one, It might be good idea to set prefetch to 5. Anyway you can tune it and seek for better performance.
 
 
- int  prefetch = 0 
Examples
VSImport:
VSImport("script.vpy", stacked=false, index=0, prefetch=4)
VSEval:
script = """ import vapoursynth as vs bc = vs.get_core().std.BlankClip clip0 = bc(format=vs.YUV422P8, color=[0, 128, 128]) clip1 = bc(format=vs.YUV422P8, color=[255, 128, 128]) clip0.set_output(index=0) clip1.set_output(index=1) """ VSEval(source=script, index=1, prefetch=4)
