Final Cut Pro, Final Cut Express: Unexpected quit with Panasonic HDC-SD9 AVCHD
Symptoms
Final Cut Pro and Final Cut Express may quit unexpectedly when using the Log and Transfer window to preview AVCHD media from a Panasonic HDC-SD9 camcorder.
Products Affected
Final Cut Pro 6.0, Final Cut Express 4.0
Resolution
The Panasonic HDC-SD9 model camcorder is currently not qualified for use with Final Cut Pro or Final Cut Express. Although some devices that are not qualified may work to some extent with Final Cut Pro and Final Cut Express, in this case the camcorder may not perform as expected.
To find devices qualified for use with Final Cut Pro and Final Cut Express, refer to Qualified Devices for Apple Pro Applications.
Additional Information
This camcorder’s implementation of AVCHD video uses a format of H.264 that employs “Br-frames”, which are similar to traditional MPEG-4 B-frames, but contain motion reference information. The Final Cut Pro and Final Cut Express components that preview AVCHD media currently do not recognize or handle Br-frames in AVCHD data.
Up to this point, Panasonic HDC-SD9 is not yet supported in Final Cut Pro and Final Cut Express by Apple.
