I've searched for similar issues, and while I found plenty of playback issues, I didn't see anything like what I'm experiencing.
MacPro Quad-Core Xeon 2.26 x2 (8b cores)
12 GB ram
OS 10.6.8 (can't update this due to other infrastructure)
Nvidia GeForce GT 120
FAST Fiber attached SAN
Local Raid0 media drive
I know the GPU isn't compatible with the Mercury hardware acceleration.
I've been a Premiere Pro user since version 2 and have kept current through the years. I'm happily running CS5.5 on PC's in my home office. I recently installed the trial version of CS6 on my Mac at work to evaluate for that environment, and I'm pulling my hair out trying to get over some basic issues. I have no problems with Media Encoder or AE.
In Premiere using preview or program (timeline), playback stops after roughly a second... though it varies by several frames each time. I tested this with various video files, .wav files, stills (jpeg, psd), etc. I even tested with black video and bars generated inside Premiere. The problem persists with all of the above... click play, and playback stops after about a second. Scrubbing works great... I've tried different playback resolutions. I'm not using any 3rd party monitoring devices or I/O cards on this machine.
I have FCP 7 installed on the same machine and have no trouble editing and playing 1080i video all day long.
Thanks in advance!
Thank you - that did it... it took steps 1 and 2.
The above suggestion worked for me briefly, but the problem keeps re-occuring.
I too am using Snow Leopard 10.6.8, NVIDIA gfx card (8800) and an ATI Radeon 5500.
Premiere played back fine in Lion and Mountain Lion, but I downgraded because I have old quicktime files and Final Cut 7 projects that i need to work with so Lion is not an option for me.
Bizarre behavior if you ask me.
Any help on this?
