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.
Open the File
Launch Photoshop CS3 or Photoshop CS3 Extended and choose "File" and then "Open." Locate the file containing the animation and click "Open."
Go to "Window," "Animation" to open the "Animation" palette.
Look at the panel's tab to determine whether it is in "Frame" or "Timeline" mode if you are using Photoshop CS3 Extended version.
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.
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."
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."
Launch Photoshop CS3 Extended and choose "File" and then "Open." Locate the file containing the animation and click "Open."
Click the "Animation" palette's "Menu" icon located in the top right corner. Select "Document Settings" from the list of options.
Enter the duration for your animation, choose a frame rate and then click "OK" to apply the changes.
Tips & Warnings
- Changing the delay time of frames will affect the animation's length. "No Delay" means frames will play through instantly, but increasing the delay adds time to the animation. Click on the time displayed in the bottom of a frame to change the length of the delay.
