Accidentally enabled MP rendering? Also flush/ disable the disk caches....
Hope this helps... answered the questions as best I could
- What version of After Effects? Include the minor version number (e.g., After Effects CS5.5 with the 10.5.1 update).
- Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
- What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
MacPro OS X Version 10.8.2
Processor: 2x2.4 GHz 6-Core Intel Xeon
Memory: 16 GB 1333 MHz DDR3
- What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime".
Multiple.. Mainly Photoshop CS6 compositions as well as .png files and 1 H.264 in .mov container
- If you are getting error message(s), what is the full text of the error message(s)?
- What were you doing when the problem occurred?
I am [trying] to export my composition. The full composition is 12min42sec but I have started trying to do sections at a time and am currently export 1min56sec of the composition
- Has this ever worked before?
YES. I have export 5 similar compositions prior to the current one.
- What other software are you running?
None while exporting.
- Do you have any third-party effects or codecs installed?
Yes - Auto Lip Sync
- Tell us about your computer hardware. Include CPU type and number of processor cores, amount of RAM installed, GPU, number of disk drives, and how any external drives are connected.
See above for Processor and memory info.
Startup Disk: Macintosh HD
Additional External Hard Drives: 1, connected with Firewire (I am not exporting out or from this hard drive but am using files from it)
- Do you have any third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU)?
- Are you using OpenGL features in After Effects?
Not that I am aware of, no
- Does the problem only happen with your final output, RAM preview, or both?
Mainly with final output
- Are you using Render Multiple Frames Simultaneously multiprocessing?
I haven't been but just turned it on for this last export
- What is the exact sequence of steps that you are taking?
File, Export > Add to Render Queue, Settings for Render: Best Quality, H264, Render... wait
No and I cleaned the disk cache. Still extremely slow
Have you verified the integrity of your source files? If it happens on just this one project/ composition, itr may be soemthing specific there...
Any idea what to look for? The source files are all very similar to what I have used in the other projects.
