ImageWriter doesn't write raw YV12. Try ImmaWrite() or the commandline utility avs2yuv.

@Wilbert, Not true!ColorBars(pixel_type="YV12")

ImageWriter("Fred.")Writes "Fred.000000.ebmp", etc as Avisynth YV12 extended BMP files. Granted they are not that useful except to reimport via ImageSource().

but it results in a sequence of images, not one raw YUV file.

ImmaWrite (http://www.geocities.com/wilbertdijkhof/immaavs_v141.zip) works. thank you very much.

Loadplugin("rawsource.dll")
LoadPlugin("immaavs.dll")
rawsource("e:\1080p\blue_sky.yuv", 1920,1080, "i420")
bilinearresize(352,288)
ImmaWrite("cb_yv12", type="raw", animation=true,magick_home = "C:\\WINNT\\system32")
