"Codec not Found" in 10.9.2 FCP7 stopping exports?

FCP 6 and 7 are not officially supported in 10.9. ZERO consideration was made for FCP 7 and earlier when Apple made OSX 10.9. FCP 7 was End of Lifed 3 years ago. Apple now makes FCP-X...and only supports FCP-X.

The HDV codec that is used by FCP is made by Apple. It's so proprietary, that unless you have FCP installed on a Mac computer, it's unviewable. PC's can't see it at all...period. So if Apple changed it...it's changed.

Your best bet is to export to another codec, like ProRes. It's more of a standard anyway. But if you must have HDV exports...then it'll be best to backup your computer, wipe the hard drive, and install a supported OS. The lat OS that FCP 7 works with well is 10.8.

Lesson: Never upgrade a working system unless the upgrade gives you something you really need to work. And before you do...clone your working OS to another drive, so in case something like this happens, you can easily go back to it.

YOu'll need to make or buy one of those standalone flash installers. Or downgrade to Snow Leopard via disk, and then only upgrade to 10.8. THis does entail wiping your hard drive and installing from scratch.

Apple has made things really difficult, in their strive for "simplicity."

OH....I didn't read that right. It worked for a little bit under 10.9...but then stopped.

Did you happen to add any stills to the project?

YES! Dammit, I should have caught this sooner. The stills need to be in the RGB color space, not CMYK. Many stills prepped for print are CMYK.
