Convert To Video
When users download the software, there are two setup files. One
is a2swf_setup.zip and the other one is swf2video_setup.zip.
SWF to Video converter is a software that can
be used to convert the generated SWF file to video file (avi or mpg).
There is a seperated manual for SWF to Video converter which
can be found on your computer at "Start"->"All Programs"->"SWF2Video
Software". Please check its manual for details.
Several things we need pointed out:
1. Video Codec
SWF to video converter uses video codec to convert the swf
file. However, it does not include any video codec with its installation.
It will load the video codecs which are installed on users computer already,
and users can select the codec that will be used.
By default, SWF to video uses "uncompressed full frame" codec,
the size of the converted avi file will be huge.
We tested many codecs, and our recommendation is:
-
TechSmith Screen Capture codec.
If you had
Camtasia Studio installed already, then its codec is already installed
on your computer.
It is a lossless codec which means the
quality of the video is lossless after conversion. However, Camtasia is
not
free.
-
CamStudio Lossless codec. Its performance is
as good as TechSmith codec, and it is an open source.
It is free.
It can be download from
Here.
Scroll down to the center, there is a link to download the codec. At the moment
of this writing, the version is V1.4.
-
XVid codec. It is an open source project, and
can be freely downloaded from
Here.
It is not a lossless codec, the converted video quality is not
as good as lossless codec, however, the size of the converted video is
much smaller.
There are many other codes. However, we recommend these
above ones.
2. Conversion Performance
The conversion results could depend on users computer's
configuration. Usually, the better configuration the better performance it
should be. In most cases, an average computer should be good enough for the
conversion.
Shut down all other software when the computer is converting the
video.
3. Sound Conversion
-
The sound conversion results depend on computer's sound
card's performance. Usually, a new computer will have a better
quality conversion result.
-
The conversion tool uses the output of the sound card
to record the sound. The computer's volume decides the converted
file's volume. Higher volume on the computer will generate higher volume in the
converted avi file.
If the computer's sound volume is turned off, it will not have
sound after the conversion.
-
In some cases, the output of the sound card could be
disabled by the operating system, especially in Windows Vista
system. To enable the output:
-
Go to control panel and click sound icon.
-
Click Recording tab, then Right click on the background
of the tab, select "Show Disabled Devices".
-
Then, you should see items such as "Wave Out
Mix", "Stereo Mix", or something similar (depends on your PC's hardware).
-
Right Click on it and enable it.
-
Now, try the conversion again.
-
Sometimes, depends on computer's sound card, change the
audio bit rate improves the sound quality. By default, the converter uses
bitrate 112kb/s. Change it to 128kb/s may get better results.
