2. In the Realtime Playback section, select these options:
Select the Desktop Video Display During Playback option if you want to preview through the Monitor panel and your TV monitor.
Deselect this option if playback through the Monitor panel is jerky.
For External Device, choose the option that matches the camcorder or analog-digital converter you’re using to drive your TV monitor.
For Aspect Ratio Conversion, choose Hardware (If supported).
Choose External Device Audio to monitor sound as well as video through the TV monitor. This option keeps the two in sync on playback.
note: Realtime Playback plays previews instantly in fully rendered final quality. With render-free editing, you can review editing decisions
as you make them and experiment more freely. For best playback frame rates, use a Pentium® 4, 3-GHz system or better.
3. In the Export section, for External Device, choose whether to export to the specified device. This option doesn’t affect playback.
4. In the Desktop Display Mode section, choose Accelerated GPU Effects if your display adapter supports DirectX®. Otherwise, choose
Compatible or Standard, whichever gives best playback results on your system.
5. Leave the remaining Playback Settings as set by Adobe Premiere Elements, and click OK.
6. In the Project Settings dialog box, click OK.
Render an area for preview
More complex movies and InstantMovies (with effects and layered video and audio) require more processing time to display properly. If Adobe
Premiere Elements can’t display an area at full speed and quality, it adds a thin, red line in the time ruler of the Expert view timeline.
To preview one of these areas, you can first render it. Rendering processes the layers and effects and saves the preview into a file, which Adobe
Premiere Elements can use each time you preview that section of the movie. Once rendered, a section doesn’t require re-rendering, unless
changes are made to it. (In the Expert view timeline, rendered areas are marked with a green line.)
note: If you make significant changes to a rendered area, the preview file is no longer useful, and the green line changes to red. To preview
complex effects at the full frame rate, you’ll have to re-render the area.
You designate the area to render by using the work area bar in the Expert view timeline.
Set the area to be rendered
Drag the textured center of the work area bar over the section you want to preview. Make sure that you drag the work area bar from its
center. Otherwise, move the current-time indicator.
If the textured center is not visible, Alt-drag the work area bar over the section you want to preview.
Position the current-time indicator, and press Alt+[ to set the beginning of the work area.
Position the current-time indicator, and press Alt+] to set the end of the work area.
Alt-double-click the work area bar to resize it to the width of the movie.
Double-click the work area bar to resize it to the width of the time ruler, or the length of the entire movie, whichever is shorter.
Tip: Position the pointer over the work area bar to display a tool tip that shows the work area bar’s start timecode, end timecode, and
duration.
Render a preview
Set the work area bar over the area you want to preview, and click the Render button or choose Timeline > Render Work Area. (The
rendering time depends on your system’s resources and the complexity of the segment.)
You can also render a preview by setting the work area bar and pressing Enter (Windows) or Home (Mac).
