WebEx Event Center Release Notes and FAQs

•
If you hear “clicks and clacks” during playback, you may be using an older version of the WebEx
Player. Re-install the player on your computer and try again.
Q. What audio compression and sampling rates does WebEx support? Which ones should I use?
A. WebEx supports the following audio recording formats:
•
G.723 (8 kHz) This is the default setting; it is optimized for streaming over the Internet.
•
PCM (8 kHz, 22 kHz, 44 kHz) This results in higher audio quality but much larger file sizes. This is
recommended only for recordings that you distribute on a CD-ROM.
Q. How large are recording files?
A. A one-hour recording is typically between 15 and 40 MB. The size varies depending on whether you
have included chat sessions, notes, video, and other features in your recording.
Editing Recordings
Q. Can I edit recordings?
A. Yes. For recordings that were created using the WebEx WRF Player or the WebEx Recorder, Player, and
Recording Editor, you can use the WebEx Recording Editor to add, delete, or rearrange recorded data. You
can also specify segments in the recording, much like tracks on a CD, so that you can quickly navigate to
a specific point during playback. You can download the WebEx Recording Editor from your Support page.
For recordings that were made using network-based recording (Record on Server), basic editing can be
done on the Recording Properties page under Playback control, such as specifying a different start and
end time for the playback, and omitting specific panels (Participants, Chat, etc.) from the playback.
If additional editing is required, you can use the WebEx Network Recording Player to convert the recording
to a Windows Media File (.wmv) format, Flash (.swf) format, or MPEG-4 format (MP4), and then use third-
party editing tools to edit the file.
Note: The WebEx Network Recording Player does not support converting recordings to MP4 format on Mac
systems.
