I have several video clips from a PC that I need to play on my Mac G4 Ti Powerbook or my desktop G4. QT5 won't play them - message is "software not available". The sound plays fine, but no video. The video format is "I420" according to QT5. I bought Final Cut Pro and it won't play them either. These videos play just fine on all PC's including my TiPB G4 using Virtual Windows - but it's extremely choppy - unwatchable - under Virtual Windows! What can I do to convert them or play them on a Mac? My PC colleagues (more of them than us) continue to rib me that Apple is not the system to use, can't handle graphics and movies. It upsets me. Btw, I have already downloaded Indeo 3, 4 and 5 from the Apple website. Does anyone have any ideas?

There is a Mac version of Windows media Player 7 available from Microsoft. That should work with PC movies.

Cheers!

I downloaded Windows Media Player 7 for the MAC. I then launched the Windows media player and tried to open two of the video clips. I get a message "Cannot play back the file. The file format is invalid". And yet, the same files play on a PC and under Virtual Windows on my MAC. QT5 plays the sound, but no video. Windows Media Player rejects the file.

My PC properties says the Type is a "video clip". The file name ends in ".AVI". The PC did not show a codec or compression scheme line item in the properties display. I was told that no compression scheme was used although QT5 thinks its an "I420". I've reinstalled the three extensions from Apple twice. They are Indeo® Video 3, 4 and 5. They do not appear when I run the extension manager, but do appear in the extensions file. Any other suggestions? Any other ideas. I really appreciate the help.

With a quick Google search I found that 'I420' is an Intel - Indeo 4 codec. I'm not sure why QuickTime can't play this since you have installed the extensions needed for this. Try posing in Apple's QuickTime discussion forum - http://discussions.info.apple.com/we...dyC^1@.ee6ba92

What software are you using on Windows that opens the video clip? Can you use this software to export into another format that QuickTime will play?

Does QuickTime for Windows play the video? If you've got Pro - export into a standard .mov

I wish you luck.

This may help, it was updated 5/9/01 and the codec links say QT2 or QT3 "or better" so I can only assume they will help you with QT5.

Doug, thanks for the advice. The error message listed on the site you recommended was exactly the message I get. I downloaded and installed the files. No luck, I still get the same error message. It is maddening and frustrating.

Always a solution to the madness. Random possible solutions I can think of is the file itself is corrupted (but somehow Windows manages to ignore it); the codecs you installed are conflicting with something else (duplicate codecs?); you're using the wrong QT player?; or there's some sort of data in that particular file that is for Windows only and the Mac reads it as part of the encoded image for some reason.
