[edit] Changes in 2.0.8

Thread: https://forum.doom9.org/showthread.php?t=48567

• Updated installer - add icon and optional assiciation for ".avs" files.
• Hopefully fixed AviSource bug with decompressing keyframes.
• Only scripts with the "avsi" extension is autoincluded in the plugins directory.
• Fixed crash on resize on rare occasions.
• Added "show=true" as optional parameter to Normalize. This will show the maximum amplification possible without distortions.
• Fixed crash if AVI file could not be opened - also affected segmented sources.
• Exist(filename) was not present in 2.07.
• Crashbug in ResampleAudio(), if no audio was present.

[edit] Changes in 2.0.6

Thread: https://forum.doom9.org/showthread.php?t=34536

[edit] Additions:

• Added LanczosResize which uses the Lanczos3 algorithm - it provides better quality than BicubicResize in many cases.
• New ResetMask() filter: sets the mask to "all-opaque" (RGB32 only).
• Added optional pixel_type parameter to AVISource and siblings to force a decompression format (YUY2, RGB32 or RGB24).
• Added optional left and right parameters to Letterbox - parameters are placed after the existing to preserve compatibility.
• Added EnsureVBRMP3Sync(clip), to avoid desync of VBR-compressed mp3-soundtrack. This will slow seeking down considerably, but is very useful when using Trim() for instance. Always use before trim().

[edit] Changes:

• Added installer/uninstaller. No more need to fiddle with .reg files and regedit.
• Default alignment is now 16 bytes, which should be faster on P4.
• Added example scripts.
• Made forward seeking fallback code in DirectShowSource files - it will not freeze anymore, just be very slow, since it has to decode all inbetween frames!
• Optimizations to YUY2 BicubicResize/BilinearResize.
• Better rounding precision in BicubicResize/BilinearResize.
• ChangeFPS() now changes the framecount (thanks to Xesdeeni).
• AVI files, that contains an invalid first frame are now rejected - there is no way of handling this situation gracefully. Segmented AVI's automatically skip these segments, and will NOT return an error.
• Better parameter checks on Crop() and LetterBox().
• AviSource always returns last valid frame on decompression errors.
• Added check for invalid frame 0 (mostly seen in SegmentedAviSource()).

[edit] Fixes:

• Fixed potential crashbug in Resize - real fix instead of previous hack.
• Fixed bug in RGB32 GreyScale, when with not divideable with 2.
• Fixed Trim, so negative values works as documented.
• Fixes to plugin autoloading: - freezed when invalid dll encountered, was locking files unnecessarily, now also loads avisynth plugins with VDF extension.
• Fixed wrap at right side of picture in RGB BicubicResize()/BilinearResize().
• Fixed another Chroma wrap issue in BicubicResize()
• BugFix: Fixed crashbug in Resize functions on some machines.

[edit] Changes in 2.0.5

Thread: https://forum.doom9.org/showthread.php?t=32018

[edit] Changes:

• Additions to the Compare filter (Statistics over several frames)
• Reorder function loading to hopefully give plugins precedence over filters
• Added LowPassAudio(frequency) and HighPassAudio(frequency)
• Many updates and additions to documentation.
• New function: String(value) - converts any AVSValue to string.
• Bumped number of plugins to 50 from 30
• Avisynth now allocates minimum 16MB cache, or otherwise 1/4th of free physical memory.
• Plugin autoloading (Create string regkey: HKEY_LOCAL_MACHINE\Software\Avisynth\PluginDir) (still in alpha)

[edit] Fixes:

• Crash-on-exit bugfix in SegmentedAviSource.
• Audio-related bugfix in AviSource.
• Bugfix in FilteredResizeH (see bug [ 588402 ]) minor optimizations too.
• Bugfix: TemporalSoften
• Bugfix: dropped frame (introduced in 2.04).
• Fixed bug in Pow(x,y)

[edit] Changes in 2.0.3

Thread: https://forum.doom9.org/showthread.php?t=30831

• Compressed audio support in AVISource, AVIFileSource and OpenDMLSource. Boolean parameter after clip turns it off.
• Compile fix in temporalsoften.

[edit] Changes in 2.0.2

• Fixed EMMS bug in ColorKeyMask.
• Fixed YUY2 detection issues in Layer.
• Added friendly error message for Layer ops.
• GetLeftChannel - Returns left channel.
• GetRightChannel - Returns right channel.
• MonoToStereo(clip1_left,clip2_right) - muxes two clips together as one stereo clip.
• MixAudio(clip_1,clip_2,float clip1_volume, float clip2_volume) Mixes two audio sources together.
• Added ConvertBackToYUY2(). It only uses chroma from the left pixel to avoid shifting chroma color by multiple YUY2->RGB>YUY2 conversions. ConvertToYUY2 remains unchanged.
• Added Documentation for new parameters.
• Added sound to Loop() function.
• New function ConvertToMono(clip) - convert stereo to mono.
• New function KillAudio(clip) removes audio from clip. Use this if you get crashes with compressed AVI sound.
• New filter: ColorKeyMask + bugfix in Layer.
• New function Normalize(clip, float max_left, float max_right). Normalizes audio. Both floats are optional. If maximum values (0 to 1) are used, the stream will peak at this level, otherwise the peak will at full volume.
• TemporalSoften (MMX & C ) (previously released as plugin TemporalSoften2).
• MMX optimized HorizontalReduceBy2() in YUY2 mode.
• Corrected one pixel offset bug in VerticalReduceby2().
• MMX is now pixelperfect in compare with C implementations.
• Changed order in ReduceBy2() since VerticalReduceBy2 is faster.
• VerticalReduceBy2() has been MMX optimized. More than twice as fast. Filter checks if image is too small to be reduced.
• Colorbars() now also generates a test tone. Test tone is a 440Hz sine at 48KHz, 16 bit, stereo. The tone pulses in the RIGHT speaker, being turned on and off once every second.
• ResampleAudio() now skips conversion, if samplerate is already at the given rate.
• No athlon codes in merge.
• Converttoyuy2 MMX optimized.
• Fixes in greyscale() in RGB mode.
• Optimized layer() and decomb-filters.
• Compare(clip filtered, clip original, string channels="", string logfile="", bool show_graph=true).
• AssumeTFF() and AssumeBFF() to force parity.
• Documentation restructured and updated.

[edit] Changes from 2.0.0 and 2.0.1

This version is based on AviSynth 1.07d. I'm not sure what the changes are.

[edit] Changes from 1.0beta7d (April 26th, 2002)

[edit] Changes in 1.0beta7 (Dec 4th, 2001)

Based on v1.0 beta5 with the following fixes/additions:

• Resize filter fix (EMMS) from Avery.
• RGB fixes from Brad.
• Brad's Greyscale() and RGBAdjust() filters.
• Blur() and Sharpen() with two arguments, also from Brad, but with the second argument optional.
• Also, I have included a new filter called ConvertFPS() which allows a smooth frame rate conversion between NTSC and PAL.
