Keywords

💡AI VFX (Visual Effects)

AI VFX refers to the use of artificial intelligence to create visual effects in videos, enhancing them with elements that are not present in the original footage. In the video's context, AI VFX are used to transform a woman's hair into plants and vines, adding a fantastical element to the scene. This is achieved by using AI algorithms to interpret prompts and generate corresponding visual effects.

💡Runway Gen 3

Runway Gen 3 is a software platform that facilitates the creation of AI-generated videos. It is mentioned in the script as the tool used to add visual effects to the video. The platform allows users to upload images and generate videos based on descriptive prompts, making it a central component in the process of creating AI VFX.
