I have read many threads asking how the effect on this site is done( http://www.yulia-nau.de )the explanations have been really helpful to a degree, thanks.However beyond all the very smooth edits and additional effects used on the original video footage the header seems to gradually reduce the transparency from frame to the next frame. All the explanations people have given have detailed clear cuts from one keyframe to the next as the mouse moves across the screen. Can anyone else tell me if it is possible for there to be a fade in the transparency of the previous frame as the mouse scrolls across the stage. Sorry about my long winded post . Ta
