AviSynth 2.5.4 and AVSEdit 1.0 Released 2004-01-26 16:58:56 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.
