Hey mister, Thanks! I knew the solutions. 1 and 3, Not number 2 I 'll go for numer 3. The only thing I hoped was when I made one matte key I could change the gradient level , (in Avid) for difrerent scenes. Anyway thanks and maybe I contact yoy soon for a sort of masterclass 'effects' (I spoke to you at the beurs in Hiversum in may)
