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
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

9.2Using 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.
