Adobe Captivate lets you publish your projects as MP4 files
by choosing any of the following presets:
Smart devices, such as, Apple iPad and iPhone.
YouTube formats, such as, YouTube Widescreen HD, and YouTube
Widescreen SD.
Any custom settings.
Note: F4V publishing is replaced with MP4 publishing in Adobe Captivate
5.5 and later.
When you select a smart device or a YouTube format, Adobe Captivate
automatically sets the optimum video settings for the chosen option.
If you have used a device or a YouTube preset while creating
the project, an appropriate option is displayed automatically in
the Publish dialog box.
Click File > Publish, and click Media.
In the Select Type list, click MP4 Video (*.mp4).
Specify a title for the project.
Specify a folder in which the project must be published.
By default, the project is published in the folder specified in
the project preferences.
Click one of the options in the Select Preset list.
Adobe
Captivate automatically sets the video settings based on the option you
select. If necessary, you can customize the settings by selecting
the Customize Video Settings check box. For the description of the
settings, see Video settings.
Note: It is recommended that you retain the
default settings for optimized outputs.
Click Publish.
After publishing a project as an MP4 file, you can do the following:
Upload it to the device stores or to YouTube.
Distribute the file to your users as a stand-alone video
over email or host it on your web server.
Stream or embed the MP4 file using Flash.
Video settings- Profile
- The profile of the H.264 encoder/decoder.
- Baseline
- For mobile and video conferencing applications
- Main
- For standard-definition digital TV broadcasts
- High
- For applications and devices dealing with high definition
The
higher the profile, the higher is the complexity involved to encode
or decode.
- Level
- The degree of the required decoder for the selected profile.
The higher the level, higher is the degree of complexity associated
with the decoder.
- Bitrate Encoding
- The type of bit rate you want to use.
- CBR
- Constant Bit Rate. For every second of the video, the number
of bits used is constant and is equal to the Target Bit Rate.
- VBR, 1 Pass
- Variable Bit Rate. Some frames require higher bits than others.
If you select this option, the encoder decides how many bits to
use in such cases. So, the actual bit rate of the video is between
the target and maximum bit rate.
- Target Bitrate
- Number of bits per second to be used by the encoder.
- Max Bitrate
- The maximum bit rate to be used by the encoder. This option available
only when you choose variable bit rate.
After specifying the video settings, click Test Settings to verify
whether the custom settings are valid.
Some best practices while customizing the video settings:
The higher the profile or level, the greater is the
chance of reducing the file size.
Constant bit rate provides a file with lower size compared
to variable bit rate.
When you specify a variable bitrate,
the encoder decides when to use more bits to maintain good quality.
The file size increases when more bits are used. You may encounter
issues while streaming such files as more number of bits can be
downloaded to show specific sections of a movie.
Upload projects to YouTube directly from Adobe CaptivateClick File > Publish to YouTube.
Adobe
Captivate converts your project to an MP4 file at the back end.
After the conversion is completed, the Adobe Captivate Video Publisher
dialog box, and the YouTube Login window appears.
Specify your YouTube login credentials, and click Login.
In the Adobe Captivate Video Publisher dialog box, specify
the title for the project, and type in a description.
In the Tags field, type the tags for the project to optimize
your users' search for the project. Use commas or semicolons to
separate multiple tags.
Generally, the tags are the search
terms that your users use to search for your project on YouTube.
Some examples are the subject of your project, or the key terms
in the project, or the title.
In the Category list, click a category to which your project
belongs.
Click one of the following options:
Public:
To make your project available for everyone who accesses YouTube.
Private: To make your project available to only specific
set of users. After uploading the file, log on to YouTube, and provide
permissions for such users. For more information, see this website.
Click View on YouTube to view the project on YouTube.
Note: YouTube
may take a while to display the video.
Click Tell a Friend to send an email to the required people.
The default email application configured on your machine is loaded,
and the URL of the project appears in the default text of the email.
