If
you imported a clip that contains a solid black or white matte that’s
premultiplied (merged into the RGB channels instead of stored in
the alpha channel), you can remove the black or white background.
In the Timeline panel, select the clip containing
the matte you want to remove.
In the Effects panel, click the triangle to expand the
Video Effects bin and then click the triangle to expand the Keying
bin.
Drag the Remove Matte effect to the clip containing the
matte.
(Optional) If you’re animating the Remove Matte effect
over time, make sure that the current‑time indicator is in the position
you want. Click the Toggle Animation icon next to the Matte Type
setting.
Choose either White or Black for the Matte Type setting.
(Optional) If you’re animating the Remote Matte effect,
move the current‑time indicator either in the Effect Controls panel
or the Timeline panel and then change the Matte Type setting in
the Effect Controls panel.
A new keyframe appears in the Effect Controls timeline
when you move the handles in the Program Monitor or change the settings
in the Effect Controls panel. You can also adjust the interpolation
between keyframes by editing the keyframe graph. Repeat this step
as needed.
