yi 4k grayscale recording

[arimak]

It's bad that yi 4k doesn't have these simple effects like B&W, sepia, negative..

Some scripts for grayscale video (and photo) recording for yi 4k, (yi 4k+ too) ?
Maybe change Saturation parameter to 0, could be good enough.

well, after a few days I found how to set some effects...
the right command for setting it is:
t app test set_de 4

there is a few other effects like: negative, BW, 70film, purple (some videoart ), vivid,...
