How can I transfer video from my Sony AVCHD camcorder? I'm a desperate owner of a Sony HDR-XR520V and an avid Mac user.

Sony + Mac users know that the supplied footage management software—Picture Motion Browser (PMB)—is only for Windows.

Sony's advice for importing footage into the Mac is via the transfer feature of iMovie or Final Cut's "log and transfer". 

Both applications cost money, but more importantly, the footage is being transcoded, so the initial AVCHD video will not be transfered/stored into your computer.

My last attempt was to try to use PMB inside a Parallels virtual machine. 

PMB may be bloated but it has a really nifty feature for footage syncing:


At first sync, it transfers all data into your machine.
Then you may organize the imported footage into folders, however you like via the software or even Finder.
On every following sync, it transfers only the new videos.


Unfortunately, those last versions are buggy and the program crashes every time I try to sync the camcorder. I've contacted their support but they said, "the camcorder was only tested with original OSs and they do not support virtual machines." 

In conclusion: is there a tool or process that mimics PMB's sync?

I've looked into file management tools, and even rsync, but I cannot find a way to sync only the new videos, keeping in mind that the imported footage has been organized/moved into subdirectories.

I know that instead of copying I could move the videos out of the camera, so no syncing would be required but I need to keep the footage in the camera because it's being used as a playback device as well.
The new Final Cut Pro X natively supports AVCHD. The old Final Cut Pro Studio did not.

And the new Final Cut Pro X is much less expensive at only $300. 

You really should evaluate if it will meet your needs, and if your system has the specifications to run it.
