Hey everyone. I have been slowly teaching myself editing and effects. For my latest video I tried to learn how to isolate one color in a black and white video. I was moderately successful with the red jacket (?48sec in.). My question comes because my intention was to have different colors (yellow boots and blue hat) fade in one at a time, until all the clothes were colorized. I could not figure out how to do it without the previous colors fading out while the new color faded in. I use Sony Vegas Pro. Any tips for how to achieve this?
