About the Bandwidth Monitor
Adobe Captivate allows you to view how much bandwidth a selected project requires. You can see
how much bandwidth each slide requires and how well the slides stream over a variety of
connections. With this knowledge, you can make project adjustments as necessary.
To analyze project bandwidth:
1.
Open an Adobe Captivate project.
2.
From the View menu, select Bandwidth Analysis.
Adobe Captivate generates the slides and the Bandwidth Monitor dialog box appears.
3.
This dialog box contains three tabs: Slide Summary, Graph, and Project Summary. Navigate
through the tabs as necessary.
The Slide Summary displays information about each slide. The following options are on the
Slide Summary tab:
KB per sec
(Kilobytes per second) As a general rule, any frame with less than 3 KB per
second streams well over a modem Internet connection. Frames with larger amounts of
bandwidth might, depending upon several factors, cause playback to pause. If previous frames
require lower bandwidth, the higher bandwidth frame might download at an acceptable speed.
Note that the first frame in a project always has a higher KB per second value, because it is the
first frame to load and additional project information must load with it.
Seconds
The frame duration, in seconds.
Video (KB)
The size of any included video.
Audio (KB)
The size of any included audio.
Graph
This tab reveals how the project streams across time for different modem and
broadband speeds. You can view high-bandwidth frames and note how they appear on
common connection types.
Project Summary
This tab displays project summary information. Both the size and KB per
second are listed for each project item. Size is much less significant than KB per second. For
example, a 500 KB project running for 60 seconds streams at 8.3 KB per second; this requires
a broadband connection. On the other hand, a 2000 KB project running for 10 minutes
streams at 3.3 KB per second, and this will stream well even on a low-speed modem
connection.

(Optional) Click Print to print the information displayed.
5.
Click OK.
Note:
After you have identified the frames that require high bandwidth, you can reduce their
impact on the project by extending the timing for the high-bandwidth frame or the preceding
frame(s). You need to do this only if bandwidth is limited and you notice distracting pauses during
playback over the Internet.
