Chapter 4, Setting Up Realtime Effects with Adobe Premiere Pro
Creating a shadow effect
The Matrox shadow effect lets you project a realistic shadow from any source
containing key information, such as DVEs and titles with an alpha channel. You
can tint the shadow, and position, scale, and rotate it to match the angle of the
surface on which it is cast. Applying blur to the shadow can simulate the realistic
look of diffused light being projected on the source.
¦NoteIf you are working in HD, the Matrox shadow effect may require
rendering when combined with other effects.
°To set up a Matrox shadow effect:
Click the triangle beside Matrox Shadow to expand the property list.
¡ Important Either your source clip or an effect applied to your source clip must
contain alpha key information in order to create a shadow effect. For example, if
you apply a shadow effect to a clip with no alpha key information and scale it
down using Adobe’s Motion effect, you won’t see any shadow because the
Motion effect is the last effect applied, and there is no alpha key information to
create the shadow effect. Whereas, if you apply a Matrox 3D DVE to the same
clip and then apply the shadow effect, you will be able to see the shadow because
the Matrox 3D DVE effect contains alpha information.
•
Lock Colors Select this option to lock the colors and opacity values for the
top and bottom corners of your shadow. For example, the color and opacity
value you select for the top right corner will be used for all four corners of
the shadow.
•
Top Right Corner Color Use this to set the top right corner color.
