But with this command, I actually manage to output a file with the horizontally aligned images.
My problems are that:
I would like to have separate files (all things considered, I can very well do that in many FFMPEG calls, it doesn't have to be one command).
the chroma images are not grayscale
And I think I have the command for the luma image :
ffmpeg -i input.mxf -filter_complex "lutyuv=u=128:v=128" -vframes 1 y.png
And is says it's a "rgb24" image where I want it to be a "gray16"
Plus, I don't understand the lutyuv. What does the 128 mean?
And can I do the same thing for the chroma channels?
