Creating timeline animations (Photoshop Extended)
Timeline animation workflow (Photoshop Extended)
To animate layer content in timeline mode (rather than frame mode), you set keyframes in the Animation panel, as
you move the current-time indicator to a different time/frame, and then modify the position, opacity, or style of the
layer content. Photoshop automatically adds or modifies a series of frames between two existing frames—varying the
layer properties (position, opacity, and styles) evenly between the new frames to create the appearance of movement
or transformation.
For example, if you want to fade out a layer, set the opacity of the layer in the starting frame to 100% and in the
Animation panel, click the Opacity stopwatch for the layer. Then move the current-time indicator to the time/frame
for the ending frame and set the opacity for the same layer to
0%. Photoshop Extended automatically interpolates
frames between the start and end frames, and the opacity of the layer is reduced evenly across the new frames.
In addition to letting Photoshop interpolate frames in an animation, you can also create a hand-drawn frame-by-frame
animation by painting on a blank video layer.
If you want to create a SWF format animation, use Adobe Flash, Adobe After Effects, or Adobe Illustrator.
To create a timeline-based animation in Photoshop Extended, use the following general workflow.
1. Create a new document.
Specify the size and background contents. Make sure the pixel aspect ratio and dimensions are appropriate for the
output of your animation. The color mode should be RGB. Unless you have special reasons for making changes, leave
the resolution at 72 pixels/inch, the bit depth at 8 bpc, and the pixel aspect ratio at square.
2. Specify the document timeline settings in the Animation panel menu.
Specify the duration and frame rate. See “ Specify timeline duration and frame rate (Photoshop Extended) ” on
page 538.
3. Add a layer.
Add any of the following:
• A new layer for adding content.
