Troubleshooting Adobe Captivate output
Adobe Captivate was built with low bandwidth in mind. A typical project with sound (some
narration) and a modest screen size of 512 x 384 streams at approximately 2–3 kilobytes per
second. Your viewers can play this project using a 56K (or slower) dial-up modem without
waiting more than a few seconds for the project to start. Additionally, there are no pauses during
playback.
A project that streams well might have the following characteristics:
•
File Size: 777K
•
Length: 6 minutes 12 seconds
•
Audio: 286K
•
Video: 491K
•
Screen size: 608 x 460
Note:
File size depends on several factors. Larger files contain elements such as photos, images,
soundtracks, large screen sizes, rapid screen transitions, and higher quality video and audio settings.
There are a number of ways to improve the file size of Adobe Captivate output:
•
One important factor is the kilobytes per second ratio. Check the Bandwidth Analysis to find
this factor. Don't despair if your project is large; it is possible for a large project to stream well
over the Internet. For example, a 400K file might seem large, but if it plays for 5 minutes, it
streams easily over a 28.8K modem. The first slide in a project always has a longer kilobytes per
second ratio, because it is the first slide to load and additional project information must load
with it.
•
Consider your color settings and the images included in your project. Two quick tips for
reducing file size are to avoid color gradients and to avoid photo images.
•
If you are not going to upload your SWF files to an Adobe® Connect™ Enterprise, you can turn
off the Include Adobe Connect metadata option in project preferences. This option is on by
default and it adds data to your project that allows for better integration with Adobe Acrobat
Connect Professional. If you do not use Acrobat Connect Professional, turn this option off to
reduce project size.
Troubleshooting video errors
Adobe Captivate output does not play if it is published over the network with Flash Video (FLV)
files in it.
Also, FLV files do not play when the Adobe Captivate project containing progressive FLV is
published to a network share, and viewed by clicking the View output button. You can play the
FLV file in the Adobe Captivate output by mapping the network drive in MS Windows Explorer.
The FLV file must contain metadata for the video player to function correctly. FLV files created
with Flash Communication Server 1.5.2, FLV Exporter version 1.2, and Sorenson Squeeze 4.0
automatically contain metadata. Sorenson Squeeze 4.0 is included with the Flash Video Kit.
FLV files will not play when an Adobe Captivate project is hosted on a Windows 2003 web server.
