Adobe Captivate Output; Video Errors - Adobe CAPTIVATE 5 Help Manual

Last updated 4/22/2010
Compared to the Standard format of 256 colors, this format uses 16 million colors for the slides. This
High Quality
option should be used only if the Standard and Optimized options do not offer the correct color depth. The file size
increases dramatically using this option.
Note: Selecting the JPEG or High Quality format may increase the file size and the time it takes to download your
project. You should use a format other than Standard only when necessary and appropriate.

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
56 Kbps (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: 777 KB
•
Length: 6 minutes, 12 seconds
•
Audio: 286 KB
• Video: 491 KB
• Screen size: 608 x 460
Note: File size depends on several factors. Larger files contain elements such as photos, images, sound tracks, 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 400
KB file might seem large, but if it plays for 5 minutes, it streams easily over a 28.8 Kbps 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 Adobe® Connect™ Enterprise, you can turn off the Include Adobe
Connect Metadata option in the 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.

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 Microsoft Windows Explorer.
