try to sharpen a prores input with uyv422p10le pixel format using this
command:
fmpeg -v debug -i SACF/SACF-S01E01.mxf -ss 00:07:20 -to 00:07:30 -vf
"unsharp=13:13:5.0:13:13:5.0:13:13:5.0" -vcodec prores_ks -profile:v 2
-alpha_bits 0 -vendor apl0 -pix_fmt yuv422p10le SACF/CLIP/SACF-
S01E01-00.07.20-0-2.mxf
The resulting file show some chroma difference, as if chroma sharpening
occurs, but there is no detectible luma sharpening. If I change the
command to "unsharp=13:13:5.0" then there is no detectible change at all
between source and output. If I add a pixel format filter in front like
this "format=yuv420p,unsharp=13:13:5.0" then there is clear luma
sharpening in the output.
