Border Colour
Borders can use up to three individual colours to create the effect. The
number of colours used depends on the type of border you have selected, so
if you selected Single then only the first colour is used, but if you selected
Triple then all three colours will be visible. The results of choosing different
colours are best seeing through experimentation. You can either defined each
colour using the given sliders, or you can select a colour using the standard
Windows colour picker.
Transparency
To make the video transparent, use this panel to enable transparency and then
use the slider to adjust it.
