I don't know exactly how it's done. At least on this machine with the installed extensions, MoviePlayer can open almost any media file. It invokes the Indeo engine just like it would when it encounters a .moov resource and summons QuickTime. About the version, I believe OS 8 installs Indeo v3.22.24.09. One thing to note though, I separately installed an extension called Windows Compressors along with Intel Raw Video which may be overriding Indeo 3.2 when it falls short. You're right, there are many different CODECs for AVI and you may not have the right one, or if you do it may be an old version. If you'd like to test the Windows Compressors or Raw Video, let me know. -Aaron ---------- From: Rick Brown <rbrown@...> To: futurebasic@... Subject: Re: [FB] [Ex-FB] Date: Sat, Mar 28, 1998, 11:09 AM How is this done, exactly? I have OS 8.0. I have MoviePlayer. I have an AVI file. Yet I cannot find any way for MoviePlayer even to open or import the AVI file, much less convert it. Also, my impression was that AVI movies (like QT movies) can be created by any of a variety of compressors. Although OS8.x may install some of the more _common_ codecs used by AVI, I don't see how it could install all _possible_ ones. For example, I see a lot of AVI's lately that use the "Indeo" (Intel Video) v5.0 codec. To the best of my knowledge, there is no such version of Indeo available for the Mac, and earlier Mac Indeo codec's won't play movies compressed with v5.0.
