My apologies that I seem to have misspoke in response to your earlier post. Although what I said about having to have the corresponding codecs installed in order to render to a particular format is true, apparently AVI is no longer available in AE's output module window regardless of what codecs you have installed ... it seems you have to go to File > Export > AVI ... something I never do so I hadn't considered it.
Sorry about that ... I guess it's been a while since I needed to render an AVI from one of my Macs so I didn't notice that anything had changed.
[Dirk D. Lopez]"I would like to know how I can install the AVI codec on my MAC"
AVI is not a codec; it's a container. Like Quicktime and other container formats, it can hold a wide variety of codecs, like DivX, DV, or Uncompressed. If you are being asked to deliver AVI files, you should find out what video codec is expected for your delivery.
