14 CaptionMaker for Windows
♦ Author the subtitles. Typically, the video file to be subtitled is also used during the
authoring process. If so then steps 2 and 3 below can be skipped because they were
already performed at the start of the authoring process.
♦ In the “Video Properties” dialog, enter the full path and file name of the video file to
be played during authoring. CaptionMaker also uses this entry as the input video file
to be subtitled.
♦ Also in the “Video Properties” dialog, enter the time code value for the first frame of
the video file (if required). CaptionMaker uses this entry to control the timing of the
overlaying of the subtitles into the video file.
♦ It is highly recommended that you run AutoSync at this point to verify the
appearance, positioning, and timing of your subtitles in the preview window.
♦ Choose “Export” in the “File” menu.
♦ Select “File Type” = “DVD/DV2000/Webcast Subtitle” or “All File Types”.
♦ In the drop down list, select “Video File (Overlay Subtitles)”.
♦ Enter the full path and file name for the subtitled output AVI video file to be
generated.
♦ Click “Finish”. CaptionMaker will display the “Video Compressor Settings” dialog.
♦ Select the desired Video compressor and compression options.
♦ Click “OK” to start the subtitling process. The progress of the operation is indicated
at the bottom of the main CaptionMaker window. The operation can be aborted by
pressing the “Esc” key.
Selecting a Video Compressor
Just before starting the process to subtitle a video file, CaptionMaker displays a “Video
Compressor Settings” dialog to allow you to select a video compressor codec. There are
many codecs to choose from, and you may have to experiment a little to get a feel for the
codecs that work best for your requirements.
There are several video compressors that are included with Windows, and many third party
video compressors are available. The “Video Compressor Settings” dialog presents you with
a list of all of the video compressors that are installed on your system. Note that some of
these compressors are installed by third party software such as video capture and DVD
burner applications, and many of these compressors are only licensed for use with the
application that installed them, so you may get an error if you try to use some of these
compressors with CaptionMaker. In addition, some video compressors may not be
compatible with the format of the video file to be subtitled or the format of the output AVI
video file to be written, so you may also get an error when CaptionMaker tries to assemble
the DirectX components using these compressors.
For detailed information about codecs, there are many web sites devoted to this topic. For
example, the following are links to sites containing general information for many common
codecs.
