  • Audio clips showing red, but are still linked

    Posted by Glenn Payne on January 21, 2026 at 8:46 pm

    Hey guys,
    I have an annoying problem I can’t figure out. I’m editing a feature and the audio clips occasionally all show red and I can’t see the waveforms. However, the clips are all still linked and still play. Sometimes they’ll turn back to blue and show waveforms and sometimes they don’t. I can restart fcpx and sometimes it fixes it and sometimes it doesn’t.

    I tried updating to 11.2 and it’s still happening. I tried deleting preferences upon start up of fcpx and I’ve tried deleting unused generated library files. Nothing seems to work. It just sort of comes and goes.

    Any guesses as to why it’s happening or what I can do to stop it?

    Thanks!

    It sounds like FCP periodically thinks it’s lost a link to a file, but it hasn’t actually lost it. It’s never happened to me. Where is the footage stored: in the Library or externally?

    Yeah, seems that’s what’s happening. The footage is all on an external hard drive. Another thing about it is that it frequently “goes red” when the computer goes to sleep and I click the space bar to wake it up.

    If the external drive is not APFS that could cause issues.

    If your system drive has less than 15% of its total capacity as free space, that could cause issues.

    Please verify both. You can select a drive in the Finder, Cmd-i to get the info you need. Let us know.

    Thanks Ben,

    there’s 5.7TB of space, out of 8TB total. The drive is ExFAT instead of APFS, but I’ve used ExFAT for about a decade and never had the issue before. Unless that’s a new problem with the newer OS.

    Technically FCP can’t write to ExFat. You may have been lucky so far, but your luck has run out. Can’t use ExFat on macOS ESPECIALLY when using FCP. That’s your issue right there.

    Oh wow. That’s interesting to hear. I’ve been using ExFat daily for about 16 years with fcp. Over 100 features, shorts, commercials, etc. I’ve never noticed any issues or had this specific problem. Thanks for the heads up. I’ll look into that.

    I know many, many folks who’ve used ExFat and lost work. I highly doubt you’ve done a feature film in FCP with an ExFat drive. It’s super unstable. We’ll just say you’ve been unusually lucky so far. Apple’s own FCP forum is full of nightmares from folks using ExFat. Apple states themselves that it’s not compatible.

    I’ve edited 7 feature films in fcp using drives formatted to ExFat, without issue. They’ve always worked great so I’ve never looked into it. Good to know there’s an issue though. Thanks for the heads up.

    So AFPS is the way to go, but it’s for Mac only right? Is there a usable format that’s able to communicate with both Mac and PC like ExFat?

    So you’re taking FCP Libraries to a Windows PC? I don’t think so. And no, there’s no really compatible format to go between Final Cut Pro and a Windows PC.

    No. I’m taking source files, final exports, and other assets from mac to pc, when needed.
