Why the duplicated clip when importing from Panasonic AG-AC160AP?
I just finished video recording a two-hour training session on a Panasonic AG-AC160AP. I ended up doing it with three clips. The first is about 2 minutes long and was someone doing an intro. The second is about one hour long, and the third is also about one hour long. Here's the problem:
When I take the SD card and insert it into the iMac, then open FCPX and select "Import Media," the second and third clips (the long ones) appear to be identical...sort of. Here's what appears to be the same: The clip previews (both video and audio), the start time, end time, and duration. However, the clip names are different (Clip #2 and Clip #3) and the Content Created information is different (both show the accurate start date and times).
In FCPX, it appears as though the second clip has been duplicated and the third clip is missing.
But when I play back the video clips on the camera, everything is fine. Clip 2 and 3 are just as they should be. Also, if I preview the clips on the iMac without using FCPX, by double-clicking on the AVCHD file in the "Private" folder, all three original clips are there, and clips 2 and 3 are different and play back just as they ought to.
All recording settings were identical on all three clips.
So it seems as though the trouble must be with FCPX.
Have you seen this happen before? Ideas for troubleshooting or a solution?
