Overview

The Capturer system is based on Windows Media Encoder. This is a freely downloadable media

encoder developed by Microsoft which enables content developers to convert or capture both live

and pre-recorded audio, video, and computer screen images to Windows Media formats for live and

on-demand delivery. A Virtual Network Computing (VNC) client is used on the presenter’s laptop to

capture the desktop screen. In case of no access to the presenter’s computer, an Epiphan box can be

used to intercept the VGA signal. For ease of use, TAU has developed an application that manages the

layout of the inputs on a dashboard. The captured video is then transcoded and uploaded manually to

Video on Demand (VoD) services at will. At the end of the process one can stream the video and any

metadata or extra features that are supported by the external VoD services.

Lecture Recording

Video Capture

Windows Media Encoder captures an area of the screen. Video captured

using any freely available software.

Audio Capture

Windows media encoder via sound board.

Data Capture

Windows Media Encoder grabs an area of the screen. Video obtained

from frame-grabber monitoring application, VNC client or any other

application within the grabbing zone. Optionally, Epiphan

(VGA2Ethernet) can be used to capture the VGA signal from the

presenter’s computer.

Content editing

Video Editing

The resulting video is a single stream and can therefore be edited by any

available video editing software, many of which are free.

Metadata

The resulting product is a single video. Metadata can be added during

recording by placing information (logo, names) on the particular area of

the screen that needs to be recorded. Metadata can be placed on the

video asset itself, as Windows Videos supports some metadata tags.
