If you have an AVI file that won't play in QuickTime. Or maybe it plays but you can't hear any audio then install the Perian QuickTime plugin. Perian is a free, open source QuickTime component that adds native support for many popular video formats. With Perian installed, any OS X application that uses QuickTime can now use these additional media types:
- Divx, XviD, FLV, AVI
- MS-MPEG4 v1, MS-MPEG4 v2, MS-MPEG4 v3, DivX 3.11 alpha, 3ivX, Sorenson H.263, Flash Screen Video, Truemotion VP6
- These formats when they are inside an AVI: h.264, mpeg4, AAC, AC3 Audio, and VBR MP3.
The intent with Perian is to make Video easier on OS X. Applications like Front Row and NicePlayer can now view these formats. Contact us if you have any questions.
