Keywords

💡AI video generator

An AI video generator refers to artificial intelligence software that can automatically create videos from text prompts or static images. In the context of the video, Pika Labs is an example of such a generator, which simplifies the video creation process by using its 'magic' to transform text or images into vivid, animated videos. This is a key concept as the video's main theme revolves around exploring and utilizing Pika Labs for video generation.

💡Text prompt

A text prompt is a piece of text or a phrase that serves as an input for the AI video generator to create content based on that input. It is a crucial element in the video as it guides the AI to produce specific types of videos. The effectiveness of the video generation depends on the clarity and creativity of the text prompt.

💡Parameters

Parameters in the context of AI video generation are settings or variables that users can adjust to control and refine the output of the generated videos. These can include aspects like video length, frame rate, style, and other qualities that make the videos more vivid and aligned with the user's vision.

💡Discord server

A Discord server is an online communication platform where users can interact with each other in real-time through text, voice, and video.
