How do you perfectly align the video to the keyboard? What cameras and set ups are you using if you've done this successfully?

@Dalton Stephens @visualmusicdesign @visualmusicdesign My suggestion is, make a mesh modable grid for the notes falldown. That way, instead of distorting the video (which will lose quality, is better to leave it untouched) we distort smoothly the grid on which the notes fall.

You could then make a new point in the grid, and then move it left or right, with unlimited points, from 1 to n, which would flexibly mold the grid around them.
