Creating MPEG4 Video Files
MP3 Sound Codec
Remember, in order for the AV300 to be able to play the video, it must have an MP3
(MPEG layer 3) stereo sound track. If the source video file did not have an MP3 stereo
sound track then your destination file will have no sound. MPG4 translator will signal
this error condition. Obviously, it is pretty useless to have the video file without sound.
What you will need in this case is an MP3 encoder for Virtual Dub to use. There are MP3
encoders (usually packaged together as an encoder and decoder) available on the
Web for you to download. If you choose to use the LAME codec, make sure that you
have a version built with the ACM front-end. You can find other MP3 codecs on the
web by using the search terms ACM, MP3 and CODEC in your favorite web search
engine. Once this MP3 codec is installed into your system, Mpeg4 Translator will be able
to create final video files with MP3 sound, even if the source video file does not have an
MP3 sound track.
If you are unsure what codecs (audio and/or video) have
been installed on your computer, you can see the list, as
shown to the left, by going to the following location. Click
on Start > Settings > Control Panel > Sounds and Audio
Devices (Multimedia > Devices for Win98SE) > Hardware >
Video Codecs and then you will see a list which includes
the Video Codecs and the Audio Codecs which are
installed in your system. Decoding of MPEG 2 video files
is currently not supported by MPG4 Translator. These are
usually .mpg or .mpeg format files, not the required AVI
file. There are other tools found on the Internet (FlaskMPEG,
Rippack, etc.) that may be downloaded in order to help
you with these file types. A good starting place is the web
site www.digital-digest.com.

Using MPEG4 Translator
To the left you see the image of the main MPG4
Translator program. When you first run the program,
if the DivX™ codec has not been installed yet, you
will be notified. You should download the codec
and install it on your computer. If the Virtual dub
program has not been installed, you will also be
notified, and you should install it (either from the
CD or the Virtual Dub website). If you have placed
the Virtual Dub program in a folder other than the
default, it will ask you to locate the file.
