You should have all the Videos saved on particular location and should be accessible via finder, if you have import all the videos under the Photos Or iTunes then Lightroom won't be able to see it.
Lightroom can import the following file types:
- Camera raw formats
- CMYK files
- AVI, MOV, MP4, and other video files
Let us know if that helps.
That doesn't help unfortunately
The files are already individual in a directory, and imported in to Lightroom (.mov files).
The issue is as I explained above: After import, Lightroom shows an entry for each video in the grid view, but will not play it (error message as described).
I have the same problem. From my experience Adobe does not work well with Apple.
