Avisynth output to YUV file?

[neo squidward]

How do I save the output from avisynth to a YUV file?

Raw YUV: open script in VDub, under video select 'fast recompress' and under compression select 'uncompressed YUV' and start to encode.

If you mean something else, please explain what you want.

I find a need to measure direct yuv values, so I came up with a format I call vyu.
clip=avisource("blah")
y=clip
u=utoy(clip)
v=vtoy(clip)
vyu=mergergb(v,y,u)
It looks strange, but you can measure values in a paint program, with the dropper tool. Red measure v, Green measure y, Blue measures u.

Another way, is to save to a special "ebmp" format,
ImageWriter(clip, string "file", int "start", int "end", string "type", bool "info")
eg
imagwriter(clip) #writes all frames with autogenerated filenames
