How to Change the Length of Animation in Photoshop CS3

Photoshop CS3 includes an “Animation panel” to add movement to image layers and shapes. In the standard version of Photoshop CS3, the “Animation” panel functions in “Frame Mode,” as it did in Photoshop CS2. “Frame Mode” shortens or extends an animation as you adjust the number of frames. Adobe introduced a new mode for the “Animation Panel” in Photoshop CS3 Extended called “Timeline mode.” This mode lets you view and edit longer animations according to time. By default, the length of the animation in “Timeline Mode” is 10seconds, but you can change the “Document Settings” to a different length.

Create brief or lengthy animations in Photoshop.

Open the File

Step

Launch Photoshop CS3 or Photoshop CS3 Extended and choose “File” and then “Open.” Locate the file containing the animation and click “Open.”

Step

Go to “Window,” “Animation” to open the “Animation” palette.

Step

Look at the panel’s tab to determine whether it is in “Frame” or “Timeline” mode if you are using Photoshop CS3 Extended version.

Frame Mode

Step

Click on the “Menu” icon in the top right corner of the “Animation” palette and select “New Frame.” Continue adding new frames to increase the length of the animation.

Step

Copy and paste frames to extend the animation. Click a frame, then hold down the “Shift” key and click on additional frames to add them to the selection. Open the menu and choose “Copy Frames.” Select the last frame in the animation and then choose “Paste Frames” from the menu. In the “Paste Frames” dialog box, pick “Paste after Selection” and then click “OK.”

Step

Click on a frame and remove it by dragging it to the trash can icon at the bottom of the palette. Repeat this step to delete multiple frames and shorten the animation. Alternatively, you can select several frames, open the palette menu and select “Delete Frames.”

Timeline Mode

Step

Launch Photoshop CS3 Extended and choose “File” and then “Open.” Locate the file containing the animation and click “Open.”

Step

Click the "Animation" palette’s “Menu” icon located in the top right corner. Select “Document Settings” from the list of options.

Step

Enter the duration for your animation, choose a frame rate and then click “OK” to apply the changes.
