Clips no longer able to be imported

[George37955611iqyc]

Hi everyone. There must be a simple solution to this but I’m completely stuck. There are certain clips that are MP.4 currently on the photos app of my Mac. I imported them all onto Premier Pro no problem. However, a day or two ago the clips were missing media. I didn't move the clips so it was very strange. I was able to locate the source for most media by moving them to a file that premier pro could read. For some reason however, random clips will no longer import and I can't link them to the original even though it was perfectly fine before. How could that even be possible? Any help would be very much appreciated.

Maybe start over?

I would say take those files and put them all into one folder, then import. You might need to delete your cache. Hold down shift as you start PP. Are your files named something like AB0001.mp4, AB0002.mp4, etc? Like they came out of the camera? You might have other files from the camera with the same name in a different folder. I suggest giving them a unique name, so it won't overlap other files elsewhere.
