Problem importing video files into Lightroom 4

avchd quicktime mov files won't import into LR4. Same files worked fine in Lightroom 3.

They are originally mts files taken on a Canon HF11 camcorder. Then I remux them to mov files (no re-encoding of the audio/video streams) using a program called "Clipwrap". The reason I do this is so that metadata changes will actually be saved into the files (I believe that Bridge and Lightroom can write into the mov container but not the mts one).

I have verified that Lightroom will read the un-muxed original MTS files ok, but is unable to do anything with my muxed MOV files. However I have deleted the original MTS files from my computer and so now this has become a major problem for me. At this point I dont even mind if they dont playback in Lightroom; I just want to be able to import them and add metadata to them.

There's known issue with AVCHD in Mountain Lion. http://feedback.photoshop.com/photosh...

Are you sure it doesn't work on (regular) Lion either?

Yes, defnitely broken on both for me.

The funny thing is that my Canon 7D files import and playback fine. The only difference between the H.264 streams in the 7D and HF11 cameras is the bitrate. The only other difference between the 2 cameras is that the 7D audio is a PCM stream and the HF11 is AC3. Maybe Lightroom can read AC3 in an MTS container but not in a MOV???

Is the AC3 stereo or 5.1?
