IPhoto won’t let me import sound with my movies

I’ve owned a Fuji HS10 bridge camera for several years, for photos and video clips that I make into iMovies. That was, until the arrival of Mavericks! I don’t know whether this caused the problem, but suddenly video clips no longer played the sound recorded with the scene. If I transfer the video clips to my iMac via Image Capture, I can program the clip to play in QuickTime Player. I then arrange for all video clips ending MOV to open and play in QuickTime. This works well. However the clips still have no sound in iPhoto. Clips transferred to iPhoto lose the MOV. I have tried to add MOV, but this doesn’t work. I have replaced my iMac and MacBook with new ones during the last month, and the problem remains. Bryan Sharpe This is all to do with codecs. A codec (short for encoder/ decoder) is an algorithm that specifies the way that multimedia information is represented using digital bits and bytes. Your Fuji HS10 records audio as a mono stream encoded with the WAV codec, which is uncompressed. The QuickTime MOV file format is just a container for multimedia that uses lots of different codecs, so knowing that a video file a MOV doesn’t tell you much about the codecs used inside. QuickTime supports WAV, so your audio plays in the QuickTime Player, but iPhoto doesn’t any more. There’s no real reason why it should – it’s a photo (not a video) app. Using it as an import app for video cameras was always a kludge. You are much better off simply importing the footage from the camera directly into iMovie, or via Image Capture to MOV files and then import the MOV files to iMovie.
