    Freezing issues with AE CS3 (Scrubbing Audio & Video, Rendering)

      I have a Mac Pro 8 core 2.8 (Jan 2008), 6GB Ram, Mac OS 10.5.2 (Clean Install), AE 8.0.2, QT 7.4.1, ATI Radeon 2600...

      I can scrub video by dragging the now line, but when I hold down the command key to scrub audio and video, After Effects saves a copy and freezes up every time... Doesn't matter sd or hd comps... I've tried removing both AE and QT plug ins & Codecs to see if any were bad... I've also tried uninstalling and reinstalling...

      Not sure if this is related, but After Effects also saves a copy and freezes up whenever it finishes rendering a composition...

      Aside from that everything else works fine, so I can get work done, just slows down the workflow a bit...

      Never had problems with AE CS3 on my Dual G5/Tiger, Though I'm not sure what I need to do settingswise on Intel/Leopard... Any suggestions would be appreciated...

          Are you using multiprocessing? If so, turn it off. The issue might simply be concurrent resource usage by multiple AE instances and/or shortage of RAM. Also: what CoDec does your source footage have? Perhaps it's a third-party issue.

            Since you have an 8-core machine and only 6 GB of RAM, you should lower the number of CPUs that are used. Read more about it here:

            Also, open up your Info panel to see what AE is doing.

              First of all I want to thank Jonas and Mylenium for your suggestions... Sorry I couldn't get back to you sooner, but I had a few deadlines to meet this week...

              I tried both suggestions... I was still getting crashes...

              Just an hour ago, I figured out the problem... I also have a MOTU 828 firewire audio interface plugged in, and it was set to output After Effects audio... as soon as I turned it off, I could monitor scrubbing audio, and I was able to render without crashes...

              I'm assuming that anytime After Effects would send audio to the 828, it would crash (including the chime after rendering)... I never had this problem before with my G5/Tiger setup, so I never considered it... I guess thats where I should have started in the first place... In the meantime, I'll have to bring this bug to the attention of MOTU and see if they can figure it out in their driver...

              Thanks again guys!
