I am wondering how I can use a color video but on the time line start the video completely in black and white, then at certain timeline points I want to use selection tool to create a mask that will bring certain areas to color.
So start black and white then have selected areas come into color. I know how to use the selection masks on the timeline using keyframes, I just cant figure how to start the video in black and white other than using the global saturation settings as I already set it to b&w in the global settings but then the reginal settings did not bring back the color.
I hope someone can understand what I am trying to do and if so any help would be very much appreciated.
Thanks.
