HELP NEEDED – black lines on render
Hi all,
I have a job i am working on that is broadcast on Friday and things are not going as well as they should. I have created a sequence in widescreen pal and all is good when looking within after effects. But when I render I get strange black lines that run along various surfaces in the sequence. For example I had a camera tracking along a 3D floor which is a solid with the grid effect. When I render I get horizontal black lines that pop on and off randomly all over the place. Another example is an image that is rotated on x and y. As the camera tracks past this I get black lines that appear to be running along the face of the images.
I have tried a few different codecs, and output types, but none of this appears to make any difference.
Any suggestions??
Thanks
Jason

I have since discovered that this problem is caused by the camera depth of field. As son as I turned this off the renders were sharp and artifact free.
But now I have no depth of field. Is this system faulty or am I missing something??

Please provide details of your source imagery. Are you using any AE Lights (Spot or Point?) and Shadows? If you are, try switching off Shadows and see if the problem persists.

I am not using lights or shadows. I am working in PAL Widescreen square pixel.
Since these problems I have done simple tests with two simple panels both rotated, and placed at different z depths. I did a focus pull from one plane to the other. In CS4 I get the error. In CS3 it works fine.
It seems there is some kind of bug in CS4 depth of field effect?
Is anyone having success with CS4 depth of field?
