I've had this problem in many AVI's & TIFF image sequences I have rendered. I render out at 300 dpi - production quality. In my scene, I have the camera moving slowly across the scene. The outer edges of polygons, in this case, the edges of a door frame flash (like a strobe effect), but only while the camera is moving. I have tried rendering with TIFF's and putting it together in Adobe Premiere and it still happens. Is there a way to get rid of this?
