In the Output Clip menu, use the Logo
column to indicate the clips on which to overlay the logo.
Click the Logo tab to access the logo
controls.
Select one or two clips to be used as
your logo:
If you select one clip, it is used as
the front clip and a luminance key is applied to it. If the clip
has multiple frames, only the first frame is used.
If you select two clips, the first is
used as the front and the second as the matte.
Use the logo controls to position and
configure the appearance of your logo, and to define in and out
points. See
About the Logo Controls.
