Hello. I’ve been figuring out how to solve this problem too. The reading of this post gives me some light. The reason why FCPX assumes a SD card as a camera is the AVCHD file archive structure created by the camera in the card (in my case shooting in the AVCHD format).

When you insert a card in your computer SD slot, it appears as PRIVATE preceded by the QuickTime icon. If you just rename it, you’ll notice that it changes as a folder. Then when you open FCPX, and click the import option the card will appear as a device and not as a camera. So you could now deselect “copy to events folder”. The only thing is that you have to click “import all” in order to have the copy to events folder available.

Results: BR DL disc not usable due to a FCP X share error. (US&8.00 loss)

Solution.:
Look Back to my alternate Encore BR project with a Quicktime H.264 1920×1080 movie exported from the original FCP X project.

Results: No Transcoding was necessary and the burning was perfect. Very decent Quality of the BluRay video.

Conclusion: Export a QuickTime Master File and create and build the BluRay disc with Encore. (CS6 in my case). This is better for large projects.

I’m dealing with the same issue. Recently I update to Mountain Lion 10.8.2 and FCP X 10.0.6. The BluRay burning process have been improved. I’ve tried all of the ways described in this post in order to shorten the long transcoding process. I have a 2h:6min project (26 GB) and this is my routine:

In FCP X Share to BluRay Pionner external drive
Select my own background picture 16×9 (cropped in iPhoto)
Select include chapter markers

It has taken about 14 hours And now is burning. It is still to long time, but other ways are much more if you export a Quicktime master file first.

Hello. I’d like to upgrade to Mountain Lion in order to improve the AVCHD files encoding process (FCPX-Compressor). And found this Thread.
Instead of using importing files, I actually ingest the NXCAM AVCHD media importing from camera and it runs perfectly.

Note: I have not updated my OS Lion to Mountain Lion.

Try this and let me know

Good Luck
