  Strange issues with 3D layers.

  Posted by Alex Pritchard on December 15, 2009 at 8:59 pm

  Hello,

  Working on a Mac and using CS3. I’ve been creating an animation. 2D drawings turned into 3D layers so I can use a cam. The problem I am having is when I render the film out I get glitches with some of the layers.

  The glitches only last for a frame or so and happen when ever i make a cut from one shot to another. Object will appear after a frame, or change size and on occasion the cam is out of focus.

  In the comp I see no such glitches, this only happens when I render the film out.

  I am new to AE so it could be something extremely simple.

  Thank you David for your quick reply.

  Looked at the Open GL settings and they seemed to already be off. I did change the Accelerated effects using: to Adaptive Resolution.

  Also in the Open GL info box It told me that ‘No compatible OpenGL video card found’

  I rendered again and the same problems seem to occurred. Clipping frames at random points.

  Thanks again Dave,

  I do have a 2gb Duel Processor with 1g Ram. It’s stretched at times, but seems to be able to do the job. It also seems i have LOTS to learn.

  I’m only using a single camera layer, moving it when ever I want a new shot. I’m not sure if this is a bad way to work, but I couldn’t see any advantages to using multiple camera angles and didn’t have any problems (until now)

  I will look into compression. I’m playing out at full resolution using H.264. It looks great but does leave me with a 2g file.

  Thanks for giving me such a thorough answer. Wishing you a Merry Christmas all the way from London, England.

  Does everything look ok when you RAM preview?

  I’d suspect that this camera treatment is your problem. You might have accidentally created additional keyframes that you don’t want. If you’re not looking for one seamless camera move, it might be better to split your camera layer.
