Showing the Flow of Time

You wouldn't use a telescope to see the knees of an ant. And you wouldn't use a microscope to look at the man in the moon. Similarly, different scales of time require different ways of viewing. The Streamer block shows roughly a half minute of time. The kinds of things that show up well at that time scale include camera motions, edit transitions, and things entering and leaving the frame of view. The playback viewer below the Streamer shows a smaller time scale, less than a second. It provides a more close-up view of things like transitions.


  Edits and Camera Motion

This Streamer block shows a series of four transitions: a cut, a wipe, a dissolve, and a fade to and from black. It also gives a sense of the speed of each transition and the duration of the video segments linked by the transitions.

This block begins with a close up shot of the Charles River. As the camera zooms out new buildings and boats enter into view and they scan along the sides of the block in a fanning pattern. The video cuts to a shot of a rowing crew. As they exit the top of the frame they scan along the top to form an image of the full shell.

This block shows three shots, separated by two transitions: a dissolve, and then a fade to and from black. The middle shot is about the same duration as the beginning and ending shots combined.

This block begins with a barn-door wipe transition from a close-up of the water to a wide shot of a boathouse. The wipe creates an inverted V pattern on the top surface of the block. In the second shot the camera zooms out and pans, resulting in fanning and slanting patterns on the top and side. Then the video dissolves to a shot of a rowing shell. The dissolve appears on the skin of the Streamer as a soft blend between the two shots.
