The BCC Videoscope filter was designed to provide users with a helpful way
to measure the chroma and luma values in a clip. Because it is applied as a
filter, it can be moved or positioned anywhere in the filter effects stack in
the effects controls window and thereby display important information how a
filter is affecting the chroma and luma value ranges in a given input clip.

The input image can be displayed as a full frame background with the monitors
positioned on top of the image, or it can be displayed as a floating image
alongside the monitors. The floating image display can also be scaled to any
size and positioned anywhere in the frame.
