Old Media is Not Working...

I'm finding that a lot of older clips won't play and need to be converted using QuickTime movie player. Others can't be converted. Can someone please tell me what's going on?

Thanks, Eddie

It's probably in an old codec that's be deprecated in QuickTime. You wouldn't happen to know what the original codec was?

Hi Tom,

Thanks for your response to my question.

This is happening a lot... these are all very standard clips generated in FCP 7 and FCPX. They tend to be a few years old, but as you can see by the grab I posted, as recent as 2011.

The codec might be much older and still have been deprecated even if the file was from 2011. A lot of them were obsoleted in 10.9. They may still import into FCP, which accepts a wider range of codecs than the QuickTime player. Conversely there are many formats like MPEG-2 that will not open in FCP but can be converted using the QT player or the Finder.
