I'm still getting the error message in this help article
I'm trying to import avchd files from my memory card formatted by my Panasonic TS5: I've tried dragging the whole card to iPhoto, or the Private folder, or the AVCHD folder, or the BDMV folder. I still get the error message about unreadable files: "The file is in an unrecognized format."
The interesting thing is that before taking this batch of movies, I had done a test with an avchd import which caused no problem. It was the same card but had been previously formatted by a GoPro Hero3, though the avchd files were taken with this same Panasonic TS5. I merely needed to plug the card in and the videos showed up in the iPhoto import window ready to go. Once that testing was done I committed the fatal flaw of formatting the card on my TS5, and now iPhoto doesn't see the videos automatically, whether they're the only files on the card, or several amongst pictures and mp4s as well, and I can't even drag and drop the disk.
Any suggestions?
