  Render Creates Distortion/Fuzz/Ghosting [CS3]

  Posted by Qmpmp on October 23, 2007 at 4:03 pm

  Hello, i am rendering a 3500 frame targa sequence at a resolution of ~3500×2500
  it is for film transfer hence the large resolution.

  When rendered on a dual core intel PC (2gb ram, 2.9ghz) i get a memory error after a few frames and it crashed.

  When rendered on a G5, it makes it thru but the images are distorted, fuzzy, and there are bands of grain that slide accross the image, including wierd tranparencys etc.

  What is causing this problem? what can i do to get this thing to render properly? it renders just fine if i do it at half resolution… but i can’t get anything right @ full res!

  thanks in advance for any help

  It is very important that you configure you machine well, starting from the /3b boot ini switch to a proper page file on non boot hard drive to implementing multiprocessing in AE options.
  Also, increase the amount of memory AE can use and implement a cache drive on a fast SCSI or SATA hard drive

  An easier quick solution (though the other suggestions are a good long-term strategy for sure) is to just use the secret menu to have AE purge the cache every few frames when rendering, which will help dramatically with memory problems.

  To access the secret menu hold ctrl, alt and Shift (at the same time) and, while holding those down, go to EDIT>PREFERENCES (After Effects>Preferences on Mac), and select GENERAL. From there a new window will open. Pull open the drop-down list of preferences and at the bottom “Secret” will now be available. Set it to purge every few frames.

  This should help. As for the streaking weirdness, that doesn’t sound good. I doubt memory issues are at play here.
