For a video on working with Image Sequences, see
Alpha channel rendering in video and image sequences (Photoshop Extended)
Video and image sequences with alpha channels can be straight or premultiplied. If you’re working with video or
image sequences containing alpha channels, it’s important to specify how Photoshop Extended interprets the alpha
channel to get the results you expect. When premultiplied video or images are in a document with certain
background colors, you may get undesirable ghosting or halos. You can specify a matte color so the semi-transparent
pixels blend (multiply) with the background without producing halos.
Ignore
Ignores the alpha channel in the video.
Straight - Unmatted
Interprets the alpha channel as straight alpha. If the application you used to create the video
doesn’t premultiply the alpha channel, select this option.
Premultiplied - Matte
Interprets the alpha channel as premultiplied with black, white, or a color. If necessary, click
the color swatch in the Interpret Footage dialog box to open the Adobe Color Picker to specify the matte color.
