Specifying alpha channel and color options

You can include a fill color and specify how Premiere treats the alpha channel of the clip.

In the Motion Settings dialog box, choose any of the following options:

Reset Removes the distortion, delay, rotation, and zoom settings for a selected keyframe.

Fill Color Specifies a background color that fills the frame behind the moving clip. To select a background color, click the desired color on the thumbnail in the Fill Color box (the pointer turns into the eyedropper tool when it is on the thumbnail), or click the color swatch above the thumbnail to access the color picker and choose a color. This color appears in previews and the rendered video program only if the clip is placed in the Video 1 track.

Alpha: Use Clip's Superimposes a clip using its existing alpha channel. This is the normal setting for titles or graphics created in another application that supports alpha channels, such as Adobe Photoshop. This option affects only those clips that have been assigned an alpha channel key type in the Transparency Settings dialog box. For information on alpha channels, see Using the Alpha Channel key.

Alpha: Create New Creates a transparent fill for clips that do not have an existing alpha channel. With this option selected, an alpha channel is created for the areas in the clip that have been assigned a key type in the Transparency Settings dialog box. See Using the Alpha Channel key.

Note: Choosing the Create New option for an image containing an alpha channel overwrites the original alpha channel when the image is superimposed.
