How can i display only the chroma plane?

I'm looking for a function to display only the chroma plane, similar to histogram(mode="luma")

Does such a function exist?

In case you've loaded mt_masktools anyway, shorter command:

mt_lut(Y=-128,U=2,V=2)

Though, displaying a YV12 (or YUY2) clip "without luma" is basically not possible. You always have to use some luma.

thanks for the info Didée, some luma is okay, i needed this command to see how much a denoiser blurred the chroma plane vs another denoiser.
