main storage. These proxies are then used for a play-out instead of the
original material in the timeline and on-the-fly handled operators.
Depending on your system capabilities all timeline elements, i.e. clips as
well as operators (such as transitions or color corrections), can be sub-
ject to a prerendering. For example, when using a clip of a resolution
that exceeds the real-time capability of your DVS system, it will be
marked visibly in the timeline that it is not real-time capable. In order to
play it out in real time you will have to prerender it beforehand and it
will be rendered in the format that is currently set as the video output
format. The prerendered proxies carry project specific file names same
as the proxies created from the bin and are generated and administered
by the Edit Tool automatically. The links to prerendered proxies will be
stored in the project file, and when opening the project later again, it
will not be necessary to render them anew.
When working with prerendered data you may get proxies on the stor-
age that are no longer required for your current project but occupying
disk space. This will happen, for example, as soon as a timeline element
was prerendered and afterwards deleted or changed. Even a switching
of the video format will make the already prerendered data obsolete
due to the fact that the extra images may no longer coincide with the
newly selected format. Because the software can never be sure when
proxies are truly obsolete for a project, they will remain on the storage
of your system. Nevertheless, to delete prerendered data you can use
the menu option Delete prerendering on the context menu of a video
clip (see section “The Context Menu of Video Clips” on page 6-61).
To recognize the prerendered data belonging to one project
easily it is recommended to store them project specific for each
project separately. For further information about this please re-
fer to section “Notes on Project Management” on page 2-14.
Related to a prerendering of timeline elements are the Preren-
der all menu option on the menu Project (see section “Prer-
ender all” on page 9-15) and the section “Real-time Capability
of Clips” on page 4-13, section “Jobs” on page 4-33 and sec-
tion “Prerendering of Timeline Elements” on page 6-46.
