¶ Background Color Settings
UniFab provides four background color options: green, blue, black, and white, to suit different application scenarios. Users can freely adjust the background color based on their environment and preferences to achieve the best visual effect.
- Green Background: Typically used for chroma keying, commonly referred to as a green screen. This is ideal if you plan to replace the background with a different image or video, as it allows for easier removal and transparency in post-production.
- White Background: Suitable for creating a clean, minimalistic look. This can be useful for professional videos, product demonstrations, or presentations where a neutral, non-distracting background is needed.
- Black Background: Often used to create a more dramatic or contrast-heavy effect. It can highlight the subject by providing a stark contrast, making it suitable for cinematic or focused presentations.
