To convert the AVI file on your Mac system to an MP4, I’m going to use the wonderful program VLC. So why don’t default video players support them? If they were associated with a specific program, like, say, a DOCX from a Microsoft Word file, then it would make sense, but file formats like MP4 and AVI are more universal. Not only that, but it’s more flexible and powerful than most of the commercial programs you can acquire, and who doesn’t like “free” when it comes to useful applications? It is pretty frustrating how different systems have incompatible file formats too. There are a ton of video converters available for the Mac system (and PCs too) but it turns out that there’s a terrific open source program that offers much of the same functionality and it’s free.
