Painting Frames In Video Layers (Photoshop Extended) - Adobe 13102498 - Photoshop CS3 - Mac User Manual

Alpha channel interpretation 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, it's possible to get undesirable ghosting or halos. You can specify a matte color so the semi-trans-
parent pixels blend (multiply) with the background without producing halos.
Ignores the alpha channel in the video.

Interprets the alpha channel as straight alpha. If the application you used to create the video

Painting frames in video layers (Photoshop Extended)

Paint frames in video layers (Photoshop Extended)
You can edit or paint on individual video frames to create an animation, add content, or to remove unwanted details.
In addition to using any brush tool, you can paint using the Clone Stamp, Pattern Stamp, Healing Brush, or Spot
Healing Brush. You can also edit video frames using the Patch tool.
Note: Painting (or using any other tool) on video frames is often called rotoscoping; although traditionally, rotoscoping
involves the frame-by-frame tracing of live action images for use in animation.
In the Animation or Layers palette, select the video layer.

Painting on a video layer is nondestructive. To discard the altered pixels on a specific frame or video layer, choose
the Restore Frame or Restore All Frames command. To toggle on and off the visibility of altered video layers, choose
the Hide Altered Video command (or click the eyeball next to the altered video track in the timeline).
