images, new layers are added to the image; however, only the pasted layers are visible in the destination frames (the
existing layers are hidden).
Paste Over Selection Adds the contents of the pasted frames as new layers in the image. When you paste frames into
the same image, using this option doubles the number of layers in the image. In the destination frames, the newly
pasted layers are visible, and the original layers are hidden. In
the non-destination frames, the newly pasted layers are
hidden.
Paste Before Selection or Paste After Selection Adds the copied frames before or after the destination frame. When
you paste frames between images, new layers are added to the image; however, only the pasted layers are visible in the
new frames (the existing layers are hidden).
7 (Optional) To link pasted layers in the Layers panel, select Link Added Layers.
This option works only when pasting frames into another document. Select it when you plan to reposition the pasted
layers as a unit.
8 Click OK.
Create frames using tweening
The term tweening is derived from “in betweening,” the traditional animation term used to describe this process.
Tweening (also called interpolating) significantly reduces the time required to create animation effects such as fading
in or fading out, or moving an element across a frame. You can edit tweened frames individually after you create them.
You use the Tween command to automatically add or modify a series of frames between two existing frames—varying
the layer properties (position, opacity, or effect parameters) evenly between the new frames to create the appearance
of movement. For example, if you want to fade out a layer, set the opacity of the layer in the starting frame to 100%;
then set the opacity of the same layer in the ending frame to 0%. When you tween between the two frames, the opacity
of the layer is reduced evenly across the new frames.
Using tweening to animate text position
1 (Photoshop Extended) Make sure the Animation panel is in frame animation mode.
2 To apply tweening to a specific layer, select it in the Layers panel.
3 Select a single frame or multiple contiguous frames.
• If you select a single frame, you choose whether to tween the frame with the previous frame or the next frame.
• If you select two contiguous frames, new frames are added between the frames.
• If you select more than two frames, existing frames between the first and last selected frames are altered by the
tweening operation.
• If you select the first and last frames in an animation, these frames are treated as contiguous, and tweened frames
are added after the last frame. (This tweening method is useful when the animation is set to loop multiple times.)
4 Do one of the following:
• Click the Tweens button in the Animation panel.
• Select Tween from the Animation panel menu.
