A media management system communicates to a user the availability of media data at different qualities (such as compression quality or resolution), or from different channels, that originated from one or more sources. Given a selection of media objects, whether a set of media files, a sequence of clips or other collection of objects, the corresponding sources are identified. Media objects originating from or related to each of these sources are identified. A display is generated indicating, for each channel from the source, at each quality of data originating from that source, the media objects related to the source. Each media data file originating from that source is represented according to its channel and quality, as a time span corresponding to the time span of the source from which the data originated. Logged, but not captured, media data, and other media objects, also may be represented in the display. As a result, such a graphical interface may provides a two dimensional representation of either media data of various qualities in context of the sources from which they originated, or media objects in the context of the sources to which they are related, or both.
