Unable to see underlying clip in Matrox effect
Possible cause 1 Moved clip from Video 1 track If you move a video clip
from the Video 1 track to the Video 2 track or higher (that
is, a superimpose track) for the purpose of applying a
Matrox video effect to the clip, you’ll have to apply an
Alpha Channel key to the clip in order to see the underlying
clip in your effect. You do not have to do this for video
clips placed directly on a superimpose track.
Solution Place video clip directly on superimpose track You’ll
be able to see the underlying clip in your Matrox effect
when you place it directly on a superimpose track (Video 2
or higher). For more information, see your Adobe Premiere
User Guide.
Possible cause 2 Applied Matrox video effect to a graphics clip If you
apply a Matrox video effect to a graphics clip on a
superimpose track (Video 2 or higher), you must apply an
Alpha Channel key to the clip in order to see the underlying
image.
Solution Apply Alpha Channel key Right-click your graphics clip
on the superimpose track and choose
Video Options >
Transparency
. In the Transparency Settings dialog
box, choose
Alpha Channel as the Key type.
