NConvert jpeg -> yuv422

Post by jvass »

I am trying to convert a jpeg to yuv422 with the following command:
nconvert -out yuv422 *.jpeg
and it returns the error:
This output isn't possible (not yet implemented).
Am I doing something wrong, or just simply NConvert can't do the conversion?

I am actually trying to convert the jpeg to yuv422 for use in Avidemux, and a page says XnView can do it, but I don't know how.

Please help me out. Thanks!

According to the documentation, NConvert can read but not write this particular “flavor” of the YUV format.
