[edit] Description
VapourSource is a VapourSynth script reader for AviSynth+ / AviSynth 2.6.
[edit] 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
[edit] 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.
[edit] Syntax and Parameters
[edit] 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
[edit] 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
[edit] 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)
