If you want to add video to a document, you can create a new video
layer in Photoshop Extended. You can create a video layer from a file,
or create a blank one and add a video file to it later. If you want to open
a video later, you can use the Open command from the File menu.
Photoshop opens a variety of video files and image sequences. You can
even play the video with sound by either clicking Alt (Win) or Option
(Mac) when you hit the Play button, or toggle the sound icon on the
bottom of the panel.

After you insert a video layer, you can modify it in Photoshop Extended
using the Animation panel in Timeline view. You can zoom in and out to
display the Timeline the way you want, and then drag the playhead,
also known as the current-time indicator, to the time or frame number
in the video where you want to start your modifications. You can
change the start and stop points (also known as In and Out points), trim
frames, add a fade-in or fade-out, or add animation using keyframes. A
keyframe defines the location of a property change to the video layer.
When you set at least two keyframes that change properties, such as
position, opacity, or style, you create animation.

In addition to modifying a video layer, you can split it into two new
video layers at the specific point you want in Photoshop Extended. You
can zoom in and out to display the Timeline the way you want, and then
drag the playhead to the time or frame number in the video where you
want to split it. The video layer is duplicated and appears above the
original in the Animation panel. The original layer contains the video
from the start to the current time or frame, and the duplicate layer con-
tains the video from current time or frame to the end.

If you have video or animation frames that you want to retouch or dupli-
cate, you can use the Clone Stamp and Healing Brush tool in
Photoshop Extended. The Clone Stamp tool allows you to sample con-
tent from one area of a frame (known as the source) and paint it over
another area of the same or a different frame (known as the target).
The Healing Brush tool allows you to blend the sampled content from
the source with the target to fix a problem. You can use the Clone
Source panel to set several samples from one part of a video frame and
clone or blend them in another video frame.
