UCF is a special
file format you can use to display rich media files in WebEx sessions, as well
as share any type of document, including PowerPoint and Excel files. UCF files
can contain the following types of rich media content:
Third-party rich media
content (through partner integration)
The WebEx Universal
Communications Toolkit contains a plugin for Microsoft PowerPoint that you can
use to create and share UCF files. In addition, the toolkit includes the WebEx
Document Manager, which is an offline viewer for UCF files
information about the toolkit, see the UCF Getting Started guide on the Support
page of your WebEx service site.
What do I need in order to play rich media content files?
Your computer should meet the following system requirements:
Vista, 7, 8, 8.1
Internet Explorer 7, 8, 9, 10, 11
Adobe Flash player 11 or later (for Flash files)
Windows Media Player 11 or later (for most audio and video files)
QuickTime 7 or later (for QuickTime and other audio and video
files not supported by Window Media Player)
Mac OS X 10.7 or later (Meeting Center only)
QuickTime 7 or later (for QuickTime movies)
How can I
quickly get started using rich media content files?
To make sure that
your computer is properly set up, when you schedule a meeting, select the
Request that attendees verify rich media players option, and WebEx will ask
your attendees to test their computers before they join your session.
Can rich media
content negatively impact my WebEx sessions or network capacity?
WebEx uses a variety
of techniques to minimize the impact to WebEx sessions. Although sharing rich
media content can increase network utilization, under normal conditions, the
impact to network traffic is negligible.
Can I turn off
the UCF rich media capabilities if I am concerned about bandwidth?
Yes. Ask your WebEx
site administrator to disable UCF rich media for your service site.
Can I share rich
media content files during WebEx meetings?
Yes. Just make sure
that all attendees have a media player installed on their computers; to prepare
for a meeting where you use rich media content files:
Use the Advanced meeting
scheduler and select
Attendees page, select the
that attendees verify rich media players
option. If this option is selected, when your attendees
join the session, they will be asked to test their systems to make sure that
they can play rich media files.
Options page, select the
UCF rich media for attendees option.
When you create your
presentation, preview the slide presentation to ensure that the playback
controls are visible.
Can I record
WebEx sessions that contain rich media content files?
Yes. To record the
audio from UCF files at the same time that you record the audio from a
teleconference, use a telephone transmit and receive patch such as the
DynaMetric TMP-636 or Plantronics MX-10. This allows you to send the sound from
your telephone through your computer sound card. To record video, make sure to
turn off hardware acceleration (or video overlay) on your computer video card.
For details, see the Windows Media Player online help.
What is the
difference between inserting files and using a URL? Which method do you
Insert a URL to
create a link to a file that is stored on a Web server or streaming server.
When you insert a file, you are including a file that is stored on your
computer or another computer in your network.
If you insert a
rich media content file and want to send it to another person, you must also
send the file; "zipping" the presentation and the files together is an easy way
to do this. If you use Document Manager from the UCF Toolkit, you can save the
rich media content inside the UCF file (called embedding) when saving the UCF
file. In this case, you need to send only the UCF file itself to the other
formats supported for each media type?
WebEx UCF supports
these types of files:
