You know what keyframes are? just turn on automatic keyframing and set the angle at the beginning and at end. everything inbetween should be interpolated.
... i strongly suggest that you read the fine manual, since you obviously haven't. bye andraz On Wed, 2007-04-04 at 15:26 +0000, [EMAIL PROTECTED] wrote: > Guys, > I have transparent graphic of a compass that I would like to overlay on a > video.
