This means that any MOV files containing WMV3/WMA, DivX/MP3, muxed MPEG2/DTS, etc encoded A/V data are still 'QuickTime' files even if they cannot be played natively in a QT media player.īasically you have two options. iMovie files exported using legacy codecs will only play in a legacy compatible player while current QT X players will automatically attempt to convert them to more modern compression formats if possible. FCE content exported using 'pro' codecs will only play on systems configured with these same 'pro' codecs. What you can do primarily depends on the codecs used for export and how you are trying to distribute/access the online content. Is there some fix for this I can do on my end beyond redoing all the videos? It is not possible to recreate all these videos nor is it reasonable to ask any viewer to download an older version of quicktime.

The newer version of quicktime will not work.

Only older versions like 7.5.5 will work. These movies were put in quicktime format.

I have many videos on a website created with final cut express and older versions of iMovie.
