Adobe Photoshop CS5 Extended offers powerful animation features, including the ability to edit your work in timeline mode. The default frame rate for a new Photoshop file depends on your document preset. For example, NTSC video uses 29.97 frames per second, or fps, as compared to the PAL video frame rate of 25 fps. Nonvideo presets, such as paper or custom sizes, default to 30 fps. Checking and changing your frame rate requires only a few clicks.
Go to the "Window" menu at the top of your screen and click "Animation." If you see individual frames in the animation palette that opens, click on the icon in the bottom right corner to change the animation mode to timeline.
Click on the inverted triangle icon in the top right corner of the animation palette to access the fly out menu.
Select "Document Settings."
Choose your desired frame rate from the drop-down menu or enter a custom frame rate in the field to the right of the drop-down menu.
These steps also work for animation in Photoshop CS3 and CS4 Extended.
