To Remove A Black Or White Matte - Adobe PREMIERE PRO 2 Manual

Select a color from the Adobe Color Picker and click OK.
3
In the Choose Name dialog box, type a name for the new matte and click OK.
4
The matte appears as a still image in the Project panel.
Brightly colored mattes can serve as temporary backgrounds to help you see transparency more clearly while you
adjust a key effect.

To remove a black or white matte

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.
1 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
2
Keying bin.
Drag the Remove Matte effect to the clip containing the matte.
3
(Optional) If you're animating the Remove Matte effect over time, make sure that the current-time indicator is in
4
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.
5
(Optional) If you're animating the Remote Matte effect, move the current-time indicator either in the Effect
6
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.
