Like the lines that appears in maps: some are single lines (black stroke) but there are others that are f.e. a yellow line with other red thinner line inside. Can someone tell me how to do that? i'm drawing a map and it would be so much better if I could that way. Thanks...
Add the write effect to your clip, set keyframes and colour it the outer colour.
Copy clip and paste it in track 2 on top of original.
Change colour of 2nd clip and make the brush size smaller and change Paint Style to On Transparant and add some brush spacing if you like.
