Previewing video or timeline animations (Photoshop Extended)
Your video or animation can be previewed in the document window. Photoshop uses RAM preview 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 palette. The number of frames cached depends on the amount of RAM available to Photoshop.
Preview a video or timeline animation (Photoshop Extended)
Do any of the following:
In the timeline, drag the current-time indicator.
Use the playback buttons at the bottom of the Animation palette.
Press the spacebar to play or stop the playback.
Note:
To see a more accurate preview of an animation created for the web, preview the animation in a web browser. Use
the browser’s Stop and Reload commands to stop or replay the animation. Open the Save For Web & Devices dialog box
and click the Preview In Browser button.
Enable frame skipping (Photoshop Extended)
Photoshop Extended can skip uncached frames to achieve real-time playback.
With the Animation palette in timeline animation mode, click the Animation Options icon
and choose Allow
Frame Skipping from the Animation palette menu.
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. 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.
1
Connect a display device, such as a video monitor, to your computer via FireWire (IEEE 1394).
2
With a document open in Photoshop, do one of the following:
If you don’t want to set output options for viewing your document on a device, choose File > Export > Send Video
Preview To Device. You can skip the rest of the steps in this procedure.
To set output options before viewing your document on the device, choose File > Export > Video Preview.
The Video Preview dialog box opens. If your document’s pixel aspect ratio doesn’t match the aspect ratio settings of
the display device, you will see an alert.
Note:
The Send Video Preview To Device command uses the previous settings in the Video Preview dialog box.

Under Device Settings, specify options for the device that will display the image:
(Mac OS) To specify an output mode, select NTSC or PAL. If the output mode and the device do not match (for
example, specifying NTSC for the output mode and connecting to a device in PAL mode), black patches appear
on previewing.
