For Photoshop versions earlier than Photoshop CC, some functionality discussed in this article may be available only if you have Photoshop Extended. Photoshop does not have a separate Extended offering. All features in Photoshop Extended are part of Photoshop.
Click the Play button in the Timeline panel.
Use the spacebar to play and pause the animation.
The animation is displayed in the document window. The animation repeats indefinitely unless you specified another repeat value in the Play Options dialog box.
To see a more accurate preview of the animation and timing, preview the animation in a web browser. In Photoshop, open the Save For Web dialog box and click the Preview In Browser button. Use the browser’s Stop and Reload commands to stop or replay the animation.
To set the timeline duration you want to export or preview, do any of the following in the Timeline panel:
Drag either end of work area bar.
Drag the work area bar over the section you want to preview.
Move the current-time indicator to the time or frame you want. From the panel menu, choose either Work Area > Set Start At Playhead or Work Area > Set End At Playhead.
To remove the portions of the timeline not in the work area, choose Trim Document Duration To Work Area from the panel menu.
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 Timeline panel. The number of frames cached depends on the amount of RAM available to Photoshop.
In the timeline, drag the current-time indicator.
Use the playback buttons at the bottom of the Animation panel Timeline panel.
Press the spacebar to play or stop playback. For additional shortcuts, see Keys for the Animation panel in Timeline Mode.
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 dialog box, and click the Preview In Browser button.
When you enable audio previews for video layers, Photoshop includes the audio in files exported to QuickTime Movie format. (See Export video files or image sequences.)
In the Timeline panel, do either of the following:
Photoshop can skip uncached frames to achieve real-time playback.
With Timeline panel in timeline animation mode, choose Allow Frame Skipping from the panel menu.
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.
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.
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.
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.
The Send Video Preview To Device command uses the previous settings in the Video Preview dialog box.
(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.
To specify the aspect ratio of the display device, choose either Standard (4:3) or Widescreen (16:9) from the Aspect Ratio menu.
The Aspect Ratio setting determines which placement options are available.
Places the center of the image at the center of the screen, cropping the portions that fall outside the display edges of the video preview device.
Displays a 4:3 image on a 16:9 display with the center of the image at the center of the screen and gray bands on the left and right sides of the image. This option is available only if you chose Widescreen (16:9) for the device aspect ratio.
Crop to 4:3
Displays a 16:9 image on a 4:3 display with the center of the image at the center of the screen and without distortion by cropping the left and right edges of the frame that fall outside the display edges of the video preview device. This option is available only if you chose Standard (4:3) for the device aspect ratio.
Scales a 16:9 image to fit on a 4:3 display. Gray bands appear on the top and bottom of the image due the difference in aspect ratio between the 16:9 image and the 4:3 display. This maintains the display aspect ratio without cropping or distorting the image. This option is available only if you chose Standard (4:3) for the device aspect ratio.
Crop To 14:9/Letterbox
Displays a widescreen image cropped to a 14:9 aspect ratio with black bands on either the top and bottom of the image (when viewed on a 4:3 display) or on the left and right sides (when viewed on a 16:9 display). This maintains the display aspect ratio without distorting the image.
Do Not Scale
Applies no vertical scaling to the image. The image is cropped if its height is greater than that of the video display.
Scale To Fit Within Frame
Increases or decreases the image height and width proportionally to fit in the video frame. With this option, a 16:9 image appears on a 4:3 display as letterbox, and a 4:3 image appears on a 16:9 display as pillarbox.
By default, the Apply Pixel Aspect Ratio To Preview check box is selected to maintain the image’s pixel aspect ratio. In general, you would deselect this option if the document’s pixel aspect ratio is assumed to be square and you want to view the image as it would appear on a computer (square pixel) monitor.
