With affordable digital cameras and video cameras, and increasingly large hard drives, multimedia information is now a viable information source. However, while multimedia information storage is becoming easier, it is still difficult to make multimedia information accessible: it is not economic to wade through a two-hour video presentation in order to find a particular quotation.
The DNE has two multimedia editors: an image editor used to edit images and an audio/video editor used to edit audio and video information.
The DNE's multimedia editing functionality is designed to make multimedia information accessible and useable. The multimedia editors offer two strategies:
•
Multimedia subdocumentation
•
Multimedia indexing
These two strategies can be applied to images, audio and video information.
A multimedia subdocument is a single audio or video clip (a sound bite or video bite ), or a detail from an image. Multimedia subdocuments created in either media editor are saved as independent tiles that are managed entirely independently from their source tiles. You can attach a subdocument to any NE, without regard to which NE the source tile is attached. Although managed independently, subdocuments always track their source tile, ensuring that context is never lost. The DNE's automatic parent-child tracking guarantees that the full context for any multimedia subdocument is only a mouseclick away.
The media editor is used to create audio and video subdocuments as well as to index audio and video tiles. It can be used to create two kinds of audio or video tiles:
•
A subdocument tile manages a single audio or video clip that bookmarks a passage within a source recording.
•
A session manages a visually navigable index of the source recording, allowing you to find passages within audio or video information as quickly and easily as you do with text information.
The image editor performs similar functions as the media editor, but with images. It can be used to create three kinds of image tiles:
•
A highlight tile saves a detail from a single source image.
•
An annotation tile allows you to add text, lines, circles, boxes and shading to an image.
•
A scrapsheet manages multiple details from multiple source images, each of which is hyperlinked from its detail.
Media editing can be done in any of the three workrooms.
