How do you record a midi video but have the background around your hands be blacked out? (I have a green screen if needed)

You can use a black blanket and set the britghtness to minimum with any video editing software. I do it that way on my channel. Is that what you are looking for?

u cannot do it in SeeMusic for now, I believe the feature will come in the future... u can use any video editing software to black out the floor.
