Generated Video Content: This is an explanation of how AI models create video segments
In the realm of artificial intelligence, video generation has taken a significant leap forward with the introduction of latent diffusion transformers. These innovative models are blurring the lines between traditional neural networks and transformers, offering unprecedented capabilities in creating videos virtually indistinguishable from actual footage or computer animations.
The core of these video generators lies in a diffusion model, a neural network trained to reverse the process of adding random pixels (noise) to an image, transforming it into a random noise pattern. By breaking down video frames into mathematical encodings, the latent diffusion process makes the generation process more efficient than a typical diffusion model.
Transformers, designed for processing long data sequences, play a crucial role in maintaining consistency between images in the generated video. They allow video generators to be trained on a wide variety of example videos, improving video generation quality.
One of the most notable advancements in video generation is Google's Veo 3, which is capable of generating videos with sound, marking a significant step forward in the field. Google DeepMind's breakthrough with Veo 3 involved compressing audio and video data into a single data stream within the diffusion model, ensuring synchronized sound and image generation.
Videos are broken down both spatially and temporally for video generation, similar to cutting small cubes from a stack of video frames. This process allows the model to work in a latent space, compressing video frames into a mathematical encoding, requiring enormous computational power.
In 2025, the landscape of video generation saw significant changes with the release of OpenAI's video model Sora, Google DeepMind's Veo 3, and AI video startup Runway's Gen-4. OpenAI achieved consistency in Sora's video generation by combining its diffusion model with a Transformer model, a practice now standard in generative videos.
The latest generation of video generation models are called latent diffusion transformers. These models are primarily developed by companies like OpenAI and research alliances focusing on generative AI technologies. While specific firms leading in latent diffusion-based video transformers are not explicitly named in the available search results, OpenAI is a prominent company known for advanced diffusion and transformer models in AI.
Netflix made its foray into AI video technology with its new series "The Eternaut," marking the first official use by a TV provider. The use of these advanced video generators in the entertainment industry is expected to grow, thanks to their potential for increased efficiency.
Sora and Veo 3 are now available in the apps ChatGPT and Gemini for paying subscribers. The compressed individual frames are converted into a playable video that the large language model deems a good match to the user's input. The diffusion model works in conjunction with a large language model that controls the refining process and guides the diffusion model towards images that match the textual prompt.
As we move forward, diffusion methods are expected to play an increasingly important role in the future of video generation, potentially revolutionizing the way we create and consume visual content.
