Black Clips in keyword collection

Hi all,

I'm new to this forum and Final Cut Pro X.

I am currently editing a project and am a little confused.

A few of my clips in my project are black, but still show up when I play them or click on them in the timeline. It's just the library where I see the black (or so it seems).

Right now, I'm trying to extend a clip on the time line, but all it does is extend it with the black at the end.

Is there a way to fix this? I tried researching this on here and other Google searches, but things that I have come across, don't seem to fit my problem.


Not sure if it helps, but I'm working with C100/AVCHD footage. I have also attached a photo too.

Any help would be greatly appreciated.

Thanks!

Jackie
