I have some Problem with fragments in AE CS5.
I use a camera who is pointing on some graphic-objects (3D-Layer). This are *.ai and *.jpg files. I setup the position of the camera and used the „depth of field“ to blurred the objects in the „background“ (focus/aperture). On the edge of the focused part and the blurred part are some little fragments (see image, on the middle-right side).
They changing there aligment when I move the camera. The graphik of the background ist all good and works fine in the other scenes.
The fragments are showing up in the projekt-file, not just on the export.
How can I get rid of them (settings of the camera, export-Settings)? Any advices?
Switch your project to 16bpc or 32bpc or manually create the DOF range by using compound blur effects fed with a suitable gradient map. That's simply a precision problem because your focus region is so tight.
Ah, I didn't recognise this setting ;-) this helped and fixed the issue - too obvious. Thanx a lot.
