Thread: Question: Glowing overlay with green screen

    Default Question: Glowing overlay with green screen

    Now I'm not sure how to do this and I've tried a couple of ways but with no good results. Sense i probably won't explain it that good i'm going with picture by picture to help you help me
    Here's the original clip i wanna add effects to.

    Now it's going to make a downward motion.

    So i imported the movie into Sony Vegas Pro 8 and this is what i did. I added 2 time lines and added the video to the top and a solid color (red) to the bottom time line. Then i added a Chroma Keyer (Green screen) to the video and adjusted the color so it covered my green ball (It's not all the way but Ill work the out later)

    Now that i have the ball the color i want. I want it to glow. But how would i make a green screen ball glow with a solid color? That's what I'm asking. Remember, it's a movie so i wanna have it glow where ever the ball goes in the movie. Now I'm not talking about blurring the green screen because then it makes the middle less red. I want it to keep as red as i want and be able to change the glowing amount.

    Here's a picture example of what i wanna make it look like sorta.
    The reason i wanna do this is because i don't want to have to mask it all the time. So help would be greatly appreciated.

    Can you elaborate "a green screen ball glow with a solid color" ?

    Do you mean the edge of a chroma keyed area glowing with a color other than the solid background color used in the keyed area?

    Try using the secondary color filter, then select the green ball and use the hue to change it color.

    Have a look at this tutorial
