Re: Video stuttering and crashing in CS6

Hello all,

Okay, just got the 4TB MyBook Thunderbolt Duo in, copied my media, started PP6,and reconnected with no problems.

Unfortunately, all my video stuttering remained. Argh.

I noticed if I switched from Full res to 1/2 things played back a little more smoothly, but I'm still getting plenty of stuttering. That's after I completely deleted my preview files and started afresh, as it were. The dropped frames indicator doesn't stay green for long on the program monitor; it changes to yellow almost immediately.

Using the Blackmagic Speed Disk app, I can see the new 4 TB Thunderbolt drive is plenty fast (averaging about 240 mbits/sec), so that's not the problem.

I'm working with 1920x1080 DSLR footage captured with the H.264 codec at about a 50 mbit data rate. When I switch to the H.264 codec for preview renders it looks awful. When I switch to the Blackmagic 10 bit or ProRes (HQ) codecs it looks dandy, but the stuttering problem persists.

I know I'm not taxing the system very much (again I'm working with a 3.4 ghz Intel i7 27" iMac purchased back in January with a 2gb video card and 12 gigs of RAM). I only have one video track and six audio tracks playing. I have the UltraStudio 3D box from Blackmagic as my external monitoring device, with the latest driver (9.5.3).

Any ideas? At this point, I'm thinking of uninstalling and reinstalling to see if that makes any difference...

Thanks again for any assistance.

Cheers,

David
