VirtualDub and Avisynth

In VirtualDub, it is possible to open mp4 files using DirectShow filter. After install DShowInputDriver.vdplugin, then mp4 is supported in VirtualDub. When using script, i.e. generating test.avs script, can use the following lines:

DirectShowSource(“c:\test\test.mp4”)

After we install avisynth, we can write scripts to allow nonlinear editing. A typical script might look like

clip=AviSource(“c:\temp\test1.avi")

clip=ConvertToRGB32(clip)

vectors=videoprocessing1(clip, param=1)

clip=videoprocessing2(clip,vectors)

return clip
