I think that this is exactly the reason why so many people here are mistakenly reporting that they are not encountering the bug. For they simply don't know in the first place how to properly import a spanned AVCHD clip via the Media Browser. These symptoms that you reported of having either an audio or video glitch at the intersection of spanned files only occur when a spanned clip is not properly imported via the Media Browser. It is conclusive confirmation that the import was not done right
Lance,
Are you saying that my files (not imported via the Adobe Media Browser) and not showing an apparent problems should have glitches? Is there any way to test for problems? I have all three tracks synchronized in the timeline and have repeatedly scrubbed cut back and forth between clips without seeing any glitches. I am assuming that you are talking glitches at the 4 GB file size boundaries and not at the switchover between media types.
All I know is that the most knowledgeable people that I have spoken to on this subject insist that in order to properly import individual AVCHD files that are part of one spanned clip, one has to use the Media Browser. I was first informed of this by Barry Green at DVXUSER.COM, who has written a number of manuals for professional Panasonic camcorders that Panasonic has actually bundled and included with these camcorders here in the USA. However, I have since been to other websites, where others have confirmed this as well. I don't think that this is an issue in contention at all here, and is generally accepted to be accurate and true.
In order to try to bolster my theory that the make and model of the camcorder plays no role here, I just today experimented with my GH3. My goal was to show that it would experience the exact same symptoms as my Panasonic AC130 and Canon HF G10. I've not shot in AVCHD since getting my GH3, and instead have been recording using the 50 Mbps IPB MOV format, that most users of the GH3 appear to indicate gives the best results with this camera. In fact, support for that format was one of the key reasons I decided to get a GH3. So today, for the first time, I recorded in 28 Mbps 1080/60p AVCHD 2.0 using the camera, thinking that AVCHD option would stress it the most. I ended up with two 4 Gig MTS files, and a small third file, all comprising the one clip.
However, I was shocked to discover that I did not experience the severe slow down in the software that I have in the past with my spanned AVCHD clips from either of my camcorders. However, Premiere Pro 6 did actually crash on me, while it was autosaving and I was playing the file on the Timeline. And crashing like that during Autosave is a symptom that I have experienced in the past when working with AVCHD spanned clips in 6.0. However, after restarting the software, I had no problem at all in editing the clip, and even exporting it. I then performed the same editing and export with the files using PP 5.5, and the performance and speed of the software was similar. PP 5.5 did not crash on me, though.
So I am not sure what to think at this point. For I was not able to fully duplicate the problems I've experienced in PP 6 with 24 Mbps 1080/24p and 1080/30p AVCHD spanned clips from my camcorders. Although the fact that the software crashed on me while doing Autosave makes me think that a problem is still in play.
