Determine the audio and video format
IMPORTANT: Newer / Easier guides
NOTE: This guide, while still working, is very outdated and uses an older and complicated method to achieve an otherwise easy task. Luckily, AfterDawn has many other guides that use free or commercial software to achieve this task and in 2008, it has never been easier before. Here are your options...
You "can" technically continue this guide but it will take a long time and it is an outdated method, therefore one of the above is highly suggested. You may also want to learn how to join two AVI files, if your video is in two or more parts. You can find that and many other great articles in our Guide section.
Now, open the AVIcodec tool and click Select button. This opens up a file dialog. Locate the AVI file you're about to convert to a DVD format, select it and click Open.
Now, you should see the video file details in the main window. In our case, we can see that the video has been encoded using XVID Mpeg-4 codec and the audio has been comporessed using MP3 format. At the bottom of the page we can also see further details for audio and video coding, such as the frequency of the audio, which is this case is 48000Hz.
Please take a look at also the fps value of the video and write it down -- normally this should be either 25.00 fps, 23.97fps or 29.97 fps (or neaby number).
If the movie is in two parts, join it
Now, if your movie is split into two or more parts, you need to join it into a one, using VirtualDub. We suggest that you use this guide to do this.
AC3 audio? Let's extract it
If you have AC3 surround audio in your movie, please read this guide in order to extract AC3 audio from the AVI file into a separate file. If you have MP3 audio in your movie, skip directly to the next part, which handles the subtitles.
