Hi Nat, I found this post regarding borders and all very clear. However, my question is, can you alter the colour of the borders (background) so that instead of Black you can alter to white etc. I have still images I have sequenced into an animation but they are not drawn to 16:9 or 4:3 ratios so can't avoid the borders, however they are drawn onto a white background therefore changing the border (background) to white makes for a full screen as such with the one background colour. Any ideas? Thanks, A.
