About AVI
AVI (Audio Video Interleave) is a container format Microsoft introduced in 1992 for video on Windows.
Older cameras, Windows software and video collections from the 1990s and 2000s.
AVI predates modern codecs and has no native support for features such as variable frame rate, so it is rarely used for new video.

Why is my AVI file so much bigger than modern video? The container predates efficient codecs like H.264, so an hour of video can take many gigabytes that an MP4 would store in a fraction of the space.
About M4A (AAC/ALAC)
M4A is an MPEG-4 audio file: the MP4 container holding only audio, usually AAC and sometimes Apple Lossless (ALAC).
Music bought on iTunes, iPhone voice memos and many podcast downloads.
Whether an M4A is lossy or lossless depends on the codec inside, which the file extension does not show.
Why convert audio to M4A? It wraps efficient AAC audio with chapter marks and cover art in one small file that Apple, Android and Windows all play.
What changes when you convert AVI to M4A
- The soundtrack of the AVI is re-encoded as M4A at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the M4A file contains the audio track of your AVI, and the picture is dropped.
Settings you can change
