{{Template:FuncDef|Echo(clip ''clip1'', clip ''clip2'' [, ...])}}

Echo forces getframe accesses to all the input clips (up to the number of frames of the first clip). The results from ''clip2'' and up are discarded. The result from ''clip1'' is returned.

This may be useful forcing alternate script paths with [[ImageWriter]] and [[WriteFile]].

'''Examples'''
 clip1 = ColorBars.Trim(0,99).ShowFrameNumber() # numbered clip (640x480)
 clip2 = clip1.SelectEvery(10, 0) # select frame 0, 10, 20, ...
 clip2 = clip2.BilinearResize(160, 120) # create thumbnails of frame 0, 10, 20, ...
 clip2 = clip2.ImageWriter(file="D:\AviSynth\Plugins\file", type="jpg")
 Echo(clip1, clip2) # returns clip1, exports clip2 (the thumbnails)
