Previewing video or timeline animations (Photoshop Extended)
Your video or animation can be previewed in the document window. Photoshop uses RAM to preview the video or
animation during your editing session. When you play or drag to preview frames, they are automatically cached for
faster playback the next time they’re played. The cached frames are indicated by the green bar in the work area of the
Animation panel. The number of frames cached depends on the amount of RAM available to Photoshop.

Preview your document on a video monitor
The Video Preview plug-in lets you preview the current frame specified in the Animation timeline (or any image open
in Photoshop) through FireWire (IEEE 1394) on a display device, such as a video monitor. You can also adjust the
aspect ratio for proper display of images.
Note: On 64-bit operating systems, you must use the 32-bit version of Photoshop to access the Video Preview plug-in.
The Video Preview plug-in supports RGB, grayscale, and indexed images. (The plug-in converts 16-bpc images to
8-bpc images.) The Video Preview plug-in does not support alpha channels. Transparency is displayed as black.
Note: The Video Preview plug-in does not lock the display device. When Photoshop is in the background on your
computer and another application moves into the foreground, the preview turns off and the device is unlocked so other
applications can use it for preview purposes.
