Description (last modified by )
try to sharpen a prores input with yuv422p10le 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 output file shows 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 "format=yuv420p,unsharp=13:13:5.0" then there is clearly luma sharpening in the output.
