Final Cut Pro: Puzzling Missing Media Message When Sharing

Where is that media that you are replacing: inside the library or external? With external media you should just save over the previous version, as the clip in your library just points to the actual media file. Is this what you are doing? Or are you replacing a file saved inside the library itself? Messing with the internals of your library can mess things up.

Did you ever find a fix? I wrapped up a HUGE project Saturday evening was was stoked I'd get to chill for the rest of the weekend. I went to export and I got the same message as you. It's now Sunday morning... I've tried several different things and nothing worked. I don' have any missing media, effects or transitions... I reinstalled FCPX... nothing has worked.

No, those suggestions didn’t solve my problem.

For others having this issue, I was able to export in H.264 after redoing the effects on several assets… not ideal, but it at least got the project out in an usable quality. The missing media icon is still on my events browser and it won’t export in ProRes.

I have that issue constantly (but no more problem that the superanoying message poping again and again).

In my case what happens is that I often reemplace files for updated versions, particularly when working with animations.

This process seems to be common sense isn't it? You are working on a project, you decide to modify something on the media so you export it from your animation software again, updated and with the same name and length... Then just replacing the updated version on the FCP library should work but... this is not something FCP likes very much and often I have issues like FCP complaining the file is missing and having to import it one by one. Worse is that I have to apply filters of edit length again, fortunatelly not very often...

Right now I have a project when even if I have no missing file on the library (now because I deleted them) the message still pops to me everytime I want to export... so I wish there would be at the least a way of just removing that message because I'm planing to export for a storyboard a screenshot of each shot, and that's going to be a number of times repeating the same again and again...

I use the external media replacement so the process most of the times, as you said, is smooth. However if the remplaced file differs in FPS, compresion rate, size or lenght, it will not work. There's a minimal number of times in which even if none of the mentioned have been changed, I still have issues. And the message (about missing file when sharing...) will pop up regardless if all the missing files have been erased. I just live with that message for most of my projects...

Does it happen again if you try to reexport your project? Try trashing your preferences.

When unexpected problems occur with one project, something one can try is to select all, copy, then make a new project and paste. See if the new project also shows the same problem.

Try the things suggested above. Also: export, anyway, and check the output. With any luck it will be all right and, if not, you will know where the problem lies and can fix it.
