Bringing in Sound
So far we've covered video without audio. Sure, silence reigned supreme in the Golden Oldies. Then came the Talkies. Ever since, we take sound for granted at the movies. But if you want your videos to communicate your message or story effectively, you need to pay attention to the sound.
Sound is NOT to be taken for granted. Aside from dialogue, sound gives "presence" to the action on screen. And the richer the sound, the more "real" the unfolding drama feels. All the more so, when you're looking at a 160x120 movie such as the one below. Though this video (with a cosmic theme!) has been converted for "streaming" across the web, we recommend that you download it for playback on your machine.

Aside from driving the narrative of the movie itself, there's a subtler effect going on. At a subtle level of perception (which is affected by the prevailing culture of the perceiver), audio enhances the power of the thumbnail movie to represent what you (and your students) have come to expect when watching broadcast television or going to the movies.

In video, there are six basic types of audio:
