Hi folks!
We are very proud to present you with another release of AviSynth, and the first release of AVSEdit.
AviSynth 2.5.3 -> 2.5.4 changes:
Additions:
* Added Overlay() for doing advanced video overlays/layers. Overlay allows to place arbitrary video on top of eachother. Clips can have different sizes, have alpha masks and even different colorspace. A large variety of blend modes are available.
* Added SSRC(int samplerate) very high quality SSRC resampling. Audio is always converted to float.
* Added SuperEQ(). SuperEQ is a very precise 16 band equalizer.
* Added ConditionalReader(). This enables users to load per frame settings into variables accessible to conditional variables.
* ShowAlpha now returns RGB, YUY2, or YV12 via the pixel_type argument. The latter two can be used to layer an RGB clip with alpha transparency data onto a YUV clip using the 3-argument form of Overlay().
* Added IsYUV(clip) to script language (it was only present in the documentation).
* Added internal audiocache by WarpEnterprises. Added automatically by the filters that need it.
* Added Histogram(mode="stereo") shows a clasic stereo graph from the audio in the clip. Some may know these from recording studios. This can be used for visualizing stereo width and potential phase problems.
* Added Histogram(mode="stereooverlay"). Draws the stereograph on top of the original image. YV12 only.
* Added ChangeFPS(linear=true/false). This will make AviSynth request frames in a linear fashion, when skipping frames. Default:true.
* Added Tone(float length, float frequency, int samplerate, int channels, string type). This will generate sound.
o Length is in seconds. Type can be "Silence", "Sine" (default), "Noise", "Square", "Triangle" or "Sawtooth".
o Defaults are Tone(10.0, 440, 48000, 2, "sine").
Bugfixes:
* Fixed out-of-bounds read in Normalize.
* Fixed compiler warnings in avisynth_c
* Better seeking precision in audio in DirectShowSource.
* Fixed crashes and Audio corruption in ConvertToMono().
* Fixed UnalignedSplice if only audio was present.
* Fixed Trim crash, if only audio was present (throws an error).
* Fixed slowdown on multiple Directshow Sources.
* Fixed green bars in small video with mode="levels" and mode="color". For Histogram
* Fixed overflow in ConvertAudioTo32bit().
Optimizations:
* Optimization: MMX in Dissolve.
Changes:
* Added Kevin Atkinsons avisynth_c 0.20 (stdcall) API.
* Updated installer. (Thanks to V_ICE for inspiration).
* EMMS is now executed between all filters to avoid potential FPU-states to be carried from one filter to the next.
* If any filter should request audio that is out of bounds, if will no longer be passed to the filter above, but the invalid parts will be filled with silence.
* Documentation restructured and much has been updated.
* Added C-versions of conditional planedifference filters, for non-ISSE machines.
As always files can be downloaded from
Sourceforge.
AVSEdit requires the DOT-net framework v1.1, and an installed version of AviSynth.
FitCD already does some avisynth 2.5x compatible scripts.
