Note

In some cases, the AVI format reading capability may depend on the codecs installed on the Windows machine. VLC can read a wide range of codecs internally, so you might have more flexibility in terms of codec options.

If you're using Microsoft software like Movie Maker, you can choose any codec you have installed that is supported by VLC. The uncompressed formats full uncompressed audio can result in very large files. On the other hand, codecs like Microsoft MPEG-4 v3 can offer a good balance between quality and file size.

For audio, uncompressed PCM is a reliable choice but will also increase the file size. MP3 would be a better option for more balanced quality and smaller file size.
