AviSynth Final description
A very powerful tool for video post-production

AviSynth was designed to be a very very powerful tool for video post-production. It provides almost unlimited ways of editing and processing videos. AviSynth works as a frameserver, providing instant and very fast editing without the need for temporary files.

AviSynth itself does not provide a graphical user interface (GUI) but instead relies on a script system that allows advanced non-linear editing. While this may at first seem tedious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner.

Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.


What's New in This Release:

· Additions
· ConvertAudio(cii) available to plugins via env->Invoke().
· Added font aspect, rotation and alpha to text routines.
· Added /* xxx */ block comments.
· Added [* [* xxx *] *] nestable block comments.
· SetMemoryMax(0) to just return current Memory Max value.
· Added planar YV12 color format to Compare() [Fizick].
· ColorKeyMask: Allow independant tolerance levels for each channel.
· Added Tweak Hue/Saturation range limiting.
· Added AudioLevels and Color2 modes to Histogram.
· Adding global OPT_UseWaveExtensible=True to your script enables WAVE_FORMAT_EXTENSIBLE audio output.
· Added ShowTime() script verb, like ShowSMPTE() but with milliseconds.
· Added BlackmanResize() and Spline64Resize().
· Modified DeleteFrame()/DuplicateFrame() to process multiple arguments.
· Added Min()/Max() script functions.

· Fixed Conditional reader/writer illegally saving IScriptEnvironment pointer.
· Fixed YV12 Blur()/Sharpen() right edge pixel corruption with non-writable input frames.
· Fixed MMX Blur()/Sharpen() code to full 8 bit precision.
· Fixed IsAudioFloat()/IsAudioInt() script functions.
· Fixed Cache memory oversubscription of SetMemoryMax() limit.

· DirectShowSource() now detects and handles non 32 bit aligned picture lines from dud codecs.
· Crop(align=true) tests actual alignment in each GetFrame call.
· Relax YV12 resizer width restriction, now mod 2 was mod 4.
· .AVSI failures during env->CreateScriptEnvironment() are now available to the GetError() interface.
· SetCacheHints(CACHE_RANGE, n) will now surrender frames to satisfy SetMemoryMax().
· CoInitialize()/CoUninitialize() now done as part of ScriptEnvironment creation/deletion.
· Much code from 2.6 base included. Typically IsYV12() changed to IsPlanar().... [ read full changelog ]
