If you have a background clip on track V2, which track should your green screen clip be edited onto?

• A. V1
• B. V2
• C. V3
• D. V4

Answer: (C)

When working with chroma keying, such as a green screen effect, it's essential to understand how layers of video tracks interact. A background clip placed on track V2 means that track V1 is available for other video elements and that the signal from V2 will be visible over V1. To properly utilize a green screen clip, it typically needs to be placed on a higher track than the background it will replace. Hence, placing the green screen clip on V3 allows it to overlay on V2, ensuring that the background on V2 is visible behind the keyed area of the green screen clip. This layering is fundamental in a non-linear editor like Avid Media Composer, where the topmost track visually dominates the back. Using V3 for the green screen enables the layering system to work as intended since the green screen will be keyed out, allowing the background from V2 to show through where the green is removed. Thus, having the green screen clip on V3 makes it the optimal choice for achieving the desired visual effect.
