NCast Presentation Recorder Reference Manual
The final processing of an archive file occurs when a Session has ended. If a Session is active an
archive file may be in an incomplete state listed as “Captured” or “Processing”. After pressing the “End
Session” button all archive files will be finished and converted into a “Ready” state.
At the end of a Session the Archive page will show a status of “Unfinished” for files which are in the
process of being hinted, optimized or fixed. When the status becomes “Ready” the archived file is ready
for download.
5.1.1. Download Button
To download one or more archives, select the files to be downloaded and click on the Download button.
In addition to the MP4 file two additional files may be retrieved:
•
XML – Contains metadata about the recording such as Title and Presenter.
•
SRT – Contains a timed text track which may be used for captioning, chaptering or event
marking. Refer to the Serial Command Reference Manual for more information on timed text
tracks.

The use of XML format allows the content to be encoded in the Unicode (UTF-8) character set.
The <main_window> and <pip_window> tags record the position of these windows at the start of a
session. This information may be useful for downstream video editing processes which wish to extract
video or graphics details from these windows.
