  Rendering Issue – Update

  Posted by Patrick Troy on September 28, 2007 at 12:34 am

  Hi there,

  I have posted a few times with related issueshere is update.

  I have a feature length ProRes Timeline with HD, HDV, DV, and Jpegs on it.

  I have had serious issues for the entire project.
  If I try to render an entire long timeline it will eventually crash.

  I can watch Activity Monitor System Memory chart and watch as Free Space gets smaller and smaller. Eventually as it gets towards zero it starts writing errors to the Console log [vm_allocate failed, error code 3, cant allocate region, etc] and eventually falls over.
  Work around is to render smaller chunks or to stop render when free System Memory is v small, save, and go again, both of which is laborious.

  These allocation errors relate to another intermittent render problem.
  After a rendering a clip it may play as a freeze frame.
  Re-rendering that clip individually corrects the problem.

  I have searched various fori and found that other programs are writing this error to Console “throwing exceptions” – Aperture, Safari when printing, Mail when Printing, Divx, even Ical, and Addressbook.

  Some of these problems have been solved by changing printer drivers etc

  I have 5gig of RAM so the memory issue would not seem to be purely hardware related. Another poster had similar issues that were slightly ameliorated when he removed his KONA card to render. I havent wanted to try this.

  The KONA tech suggests waiting for Leopard as it seems like some sort of 32 bit vs 64 bit legacy issue and the memory management of Leopard should solve it.
  He also suggested throwing even more RAM in, making smaller Sequences, and being very conscious of not having other seqs open while rendering.

  Any thoughts?

  regards
  Patrick
