AviSynth+ is a fork of the well-known frameserver featuring new functionality and optimizations not available in mainline. In the hope of modernizing AviSynth to meet present day needs and expectations, the project encourages everybody to help reach our goals: add long-sought features, energize the community, and improve developer and user friendliness. AviSynth+ is fully compatible with plugins and scripts written for AviSynth.

Version history / Release notes / Changelog
Avisynth+ r2728 (20180702)
Fix: Expr: expression string order for planar RGB is properly r-g-b like in original VapourSynth version, instead of counter-intuitive g-b-r.
Fix: Expr: check subsampling when a different output pixel format is given
Fix: ColorYUV: round to avoid green cast on consecutive TV<>PC
Fix: RGBAdjust memory leak when used in ScriptClip
Fix: RGB64 Turnleft/Turnright (which are also used in RGB64 Resizers)
Fix: Rare crash in FrameRegistry
Fix: couldn't see variables in avsi before plugin autoloads (colors_rgb.avsi issue)
Fix: LoadVirtualdubPlugin: Fix crash on exit when more than one instances of a filter was used in a script
New: Expr: implement 'clip' three operand operator like in masktools2
New: Expr: Parameter "clamp_float" (like in masktools2 2.2.15)
New: Expr: parameter "scale_inputs" (like in masktools2 2.2.15)
New: function bool VarExist(String variable_name)
New function: BuildPixelType:
Creates a video format (pixel_type) string by giving a colorspace family, bit depth, optional chroma subsampling and/or a template clip, from which the undefined format elements are inherited.
Enhanced: Limiter to work with 32 bit float clips
Enhanced: Limiter new parameter bool 'autoscale' default false, parameters now are of float type to handle 32 bit float values.
Enhanced: RGBAdjust new parameter: conditional (like in ColorYUV)
The global variables "rgbadjust_xxx" with xxx = r, g, b, a, rb, gb, bb, ab, rg, gg, bg, ag are read each frame, and applied.
Enhanced: RGBAdjust: support 32 bit float ('analyze' not supported, 'dither' silently ignored)
Enhanced: AviSource to support much more formats with 10+ bit depth.
Changed (finally): 32bit float YUV colorspaces: zero centered chroma channels.
U and V channels are now -0.5..+0.5 (if converted to full scale before) instead of 0..1
New function: bool IsFloatUvZeroBased() for plugin or script writers who want to be compatible with pre r2672 Avisynth+ float YUV format:
Enhanced: Allow ConvertToRGB24-32-48-64 functions for any source bit depths
Enhanced: ConvertBits: allow fulls-fulld combinations when either clip is 32bits
E.g. after a 8->32 bit fulls=false fulld=true:
Y: 16..235 -> 0..1
U/V: 16..240 -> -0.5..+0.5
Note: now ConvertBits does not assume full range for YUV 32 bit float.
Default values of fulls and fulld are now true only for RGB colorspaces.
New: LoadVirtualdubPlugin update: Update from interface V6 to V20, and Filtermod version 6 (partial)
Source: move to c++17, 'if constexpr' requires. Use Visual Studio 2017 (or GCC 7?). CMakeLists.txt changed.
Source: C api: AVSC_EXPORT to dllexport in capi.h for avisynth_c_plugin_init
Source: C api: avs_is_same_colorspace VideoInfo parameters to const
Project struct: changelog to git.
Include current avisynth header files and def/exp file in installer, when SDK is chosen
