Customizing Cisco MXE 3500 Release 3.3
Encoder Profiles for High Resolution Videos from
WebEx ARF Files
Revised: September 29, 2011
This document provides instructions for customizing encoder profiles so that Cisco MXE 3500 creates
a smaller-sized video with a lower frame rate and higher resolution from WebEx ARF files.
Note
Cisco MXE 3500 Release 3.3 and 3.3.1 only support ARF files with version 2.26 and below.

Introduction
WebEx ARF files have the following unique characteristics that result in a very small file size:
•
The source ARF video has a low frame rate.
•
Recording is done in the high resolution of PCs and MACs.
•
The recorded content is often a shared desktop application, document, or slideshow.
•
There are few fast moving scene changes during the WebEx recording.

Creating a New Cisco MXE 3500 Encoder Profile for WebEx ARF Files
When Cisco MXE 3500 uses a default profile to transcode a WebEx ARF file, the resulting video has a
lower resolution and higher frame rate, which can affect visibility of the content and increase the file
size up to 10 times larger than the original ARF file.
You can improve the video quality and reduce the file size by making the following changes to an
existing Cisco MXE 3500 encoder profile and saving the profile with a different encoder profile name.
•
Set the resolution to 1024 x 768.
•
Set the frame rate to the lowest possible frame rate.
Creating a New Cisco MXE 3500 Encoder Profile for WebEx ARF
Files
To create a new profile for WebEx ARF file ingestion from an existing encoder profile, follow these
steps:
Step 1
Log in to the Cisco MXE 3500 Web UI.
Step 2
From the Toolbox, expand Profile Management and click Open Profile. The Open Profile pop-up
displays the Profile Class: Encoder.
Step 3
Highlight a Profile Type, such as Flash 8, and double-click it.
Step 4
Highlight the Profile Name that you want to customize for WebEx ARF files, such as Flash_16x9, and
double-click it. The Edit Profile page displays.

Step 5
Selecting a Profile Type
Change the following encoder settings:
•
Change the Width from 480 to 1024.

•
Change the Height from 270 to 768.
•
Change the Frame Rate to 5.

Step 6
Edit Profile Page
Click Save As, and enter a new encoder profile name than is different from the default, such as
Flash_16x9_ARF.
Caution
Clicking Save overwrites the default profile.
You can now use the new encoder profile to ingest ARF files that Cisco MXE 3500 outputs as a
1024x768 Flash file.
