DragonDrop is a home-grown, internally
developed Drexel software project.
Faculty and staff first began using an early
version of the system in 2004.
First web-based version became available in
2006.
Presented as a case study in the 2007
Campus Technology “Innovators” issue
http://one.drexel.edu
This project was developed as a response to the
need to minimize the staff handling time
necessary to encode and publish rich media
destined for web delivery, and to make access to
Drexel’s current archive of web-based ondemand rich media as simple as possible
It was determined that the first issue could be
addressed by automating the encoding and
publishing process. The second would be
addressed by using modern content syndication
techniques.
RSS (Really Simple Syndication) is XML data, or
metadata, which describes or contains content
Podcasting describe a new web broadcasting
paradigm that combines RSS with web-friendly
audio (MP3) and video (MP4) files
DragonDrop makes syndication and podcasting
easy by publishing media and metadata to the
web, but that’s not all…
The brainchild of John Morris, the director of
Academic Technology Innovation at IRT
Aka Rich Media Conversion Project (RMCP)
Available on-demand only to faculty and staff
Likely to be offered to partner schools and
external institutions in the near future

DragonDrop offers many
encoding possibilities to users,
in terms of outputs and quality
This chart summarizes available
output encoding formats with the
quality settings used for encoding
The main elements that contribute
to better quality to be aware of:
height and width (resolution)
data rate (bandwidth)
Users can author content
directly in the DragonDrop
web application.
The Capture interface hooks
into the video camera and
microphone on a user’s
computer (if available)
Videos can be recorded
and then automatically
published to a user’s
capture playlist
Capture videos are
published in Flash Video
(.flv) format
Playlists are lists of links
Playlist items can be links to
items created or uploaded
into DragonDrop, or external
links (websites, images, etc)
Through the Playlist tab
users can create and
manage their Playlists, add,
edit, delete items, re-order
items, and edit metadata
Playlists are automatically
available to users as HTML
and RSS
Playlists can be password
protected by their creators
Rich media content can be
managed in the Media tab
once it's been ingested
Users can edit:
media object metadata
preview their files
delete files
add files to playlists
Media display is sortable by
title, size or format
Users can track the
progress of media they’ve
uploaded into the system
as it processes
Once jobs complete, users
receive email notification
with links to the item and
the host playlist
Items will appear in your
tracking history for 30 days
In the Options tab users
can manage personal
preferences, including:
Output templates,
which bundle together
multiple file encoding
outputs for reuse
