Sorry for not getting back sooner. I ran Verify Permissions and all checked out OK, but I don’t seem to have the issue anymore. Here’s all the specs:
Sequence:
720×480 NTSC DV (3:2)
PAR: NTSC CCIR 601/DV (720×480)
Lower (Even)
DV/DVCPRO – NTSC
Render in 8-bit YUV
Hardware:
MacPro Dual-Core Intel Xeon
2.66 Ghz
2 Processor, 4 core
6 GB memory
L2 Cache per processor, 4 MB
I recently downloaded a After Effects CS5 trial and the problem started soon thereafter..?
