AI-generated Videos: Explanation of the Process AI Models Use to Create Videos from Images and Text
In the ever-evolving world of technology, Artificial Intelligence (AI) is making significant strides in various fields, and video production is no exception. One of the latest advancements in this area comes from Google DeepMind's Veo 3, which introduced synchronized audio in AI-generated videos in 2025.
At the heart of AI video generation lies the diffusion model, a neural network that acts as a digital artist, transforming noisy data into recognizable images or video frames. This process works by iteratively refining noisy data, ensuring each frame aligns with the next to create smooth motion in videos. Latent diffusion, a technique used in this process, makes video generation more efficient by compressing raw video data into a latent space, a mathematical representation that captures only the essential features of the data.
When a user enters a prompt, a second model, often a large language model (LLM), pairs text prompts with visual data, learning to associate descriptions with visuals during training. This guidance nudges the diffusion model towards frames that match the user's request. Transformers, used in AI video generation, handle sequences of video frames and ensure continuity, preventing objects from vanishing or flickering unnaturally. They also enable models to train on diverse video formats, making them versatile enough to generate videos in any aspect ratio.
While AI video generation offers numerous benefits, it's not without its challenges. The process is energy-consuming, making it an environmental concern. Moreover, AI-generated videos can sometimes reflect online distortions, like stereotypes or unrealistic aesthetics, resulting in what is often referred to as "AI slop."
Despite these challenges, AI video generation is transforming how media is created and consumed. Tools are becoming increasingly accessible to the public, with offerings like OpenAI's Sora, Google DeepMind's Veo 3, and Runway's Gen-4 democratizing creativity. This democratization allows anyone, from professional filmmakers to hobbyists, to become filmmakers.
AI video generation is already making waves in various industries, such as Netflix's AI-enhanced visual effects in The Eternaut. As we move forward, we can expect to see AI-generated videos everywhere, blending realism with imagination, and shaping the future of media consumption.
Google DeepMind is also exploring the use of diffusion models to generate text, potentially making large language models more efficient. This development could further revolutionize the way we interact with AI, opening up a world of possibilities for the future.
