Final Steps: Test Render and Add Sound

You should now have a cool-looking effect with the hologram fading in and playing under your beam of shimmering light before fading back out again on command (see Figure 20).

Once you've finished tweaking the size and positions of the Hologram and Beam clips, and making adjustments to the fade in and fade out points, you can try a quick test render by pressing the Enter key on your keyboard. Once the render has finished, press the spacebar to see the effect in motion.

When you're happy with the overall visual effect, you may want to consider adding some kind of electronic hum to accompany the beam of shimmering light—something that adds to the feeling that an electronic device is being used by the audience actor. Sound effects of this nature can be found in various places on the Internet. Just type Trek audio effects into your search engine.

If your Hologram clip contains audio, you may well need to consider that filmmakers often distort the audio of telephone, radio—and, yes, hologram signals to signify that they're "off-screen." Without debating the wisdom of this convention too much, you can create this audio illusion yourself by adding the PitchShifter audio effect to the Hologram clip (Effects > Audio Effects), and then using this audio effect to alter the audio quality of the Hologram clip (see Figure 21).

When your project has all the visual and audio elements set to your taste, press Ctrl-S to save it, and then press the Enter key on your keyboard to render the movie again, if necessary. Once the render has completed, save the project as an AVI file by selecting File > Export > Movie (see Figure 22).
