PP CS 6 – AVCHD footage edits fine for about 15 minutes then starts to stutter
Machine is 2.2ghz I7 MBP. Clean install. 8GB 1333mhz ram. Plenty of space on 750 gb local drive. Media on LACIE FW800 external drive.
Here is the scenario. Launch PP with project footage loaded native (From Nikon D4 camera) Start to edit. Plays fine both in preview/viewer/canvas. Start editing.. then about 15-20 minutes in, video stops playing smoothly. Exit and restart PP CS6. Footage plays smooth again. Repeat process.
Any ideas why it all of a sudden slows down? Why does restarting PP clear it up?
Thanks in advance.

Hi David,
From an editing perspective, especially when adding more complicated filters or use more than one stream of video, it’s not a good idea to have your footage on your system drive. Especially because unless you chose a 7200 RPM drive at purchase, it is a 5400 RPM drive, which is too slow to handle video sustainably.
Use an external drive, and you should see improvement. You will want to look at some kind of RAID system to avoid frustration: video streams are getting larger in filesize, and although PP can handle native DSLR footage, it is taxing on the system. -
Sorry I was not clear. Footage is on external G-RAID Mini drive via Firewire 800 connection. Even with no filters/transition etc. The playback stutters after about 15-20 minutes of program use (eg; during logging footage). If it were drive speed issue, the footage would stutter from the start and and problem would not clear up with a program restart.
It’s as if PP6.0.0 and PP6.0.1 has a caching/memory management problem with AVCHD footage. Problem specific to Nikon D4, D800 footage. (I am also aware to the old problem with PP5.5 requiring Nikon footage to be renamed from mov to mpg. Tried that too. same bug.)
I am a former Apple Certified FCP, also use AVID Symphony 6. Been editing for most of my life. Its not a rookie thing. 🙂

Problem solved. Issue was in the FW800 interface. There is a bug between the way the FW800 I/O works and they way Premiere seems to do its reads/decompression/interpretation of Nikon’s codec.
I changed to the E-sata port with an expresscard interface to the MPP using the same G-Tech Mini drive and it now plays smoothly indefinitely. Yes e-sata is a faster interface, but I still think there is a FW800 bug somewhere.
