After Chatgpt, you are observing another revolution in the artificial intelligence space. OpenAI comes with video-generating tools, Sora. However, it is not available for the public yet- yes, because of safety reasons. Chat Gpt is capable of producing natural language, DALL E for images, now Sora will be available for producing high-quality visual content. In this post, we are going to describe the video generation process and capabilities of Sora.
Sora Turns Visual Data into Patches for Training
Sora uses large language models (LLMs) that create tokens to unify text-based inputs. However, instead of text tokens, Sora utilizes visual patches, which have proven to be an effective representation of models of visual data. Do not be confused with tokens and patches. LLM uses a token for texts, but Sora uses patches, which are effective in training generative models for videos and images.
Understand Sora’s Video Compression Network
Sora needs to transform videos into patches. For this, it uses a video compression network. This network reduces the dimensionality of visual data and compresses the videos both temporally and spatially. It also helps to minimize the computational power and speed up the whole process. Moreover, it also has a decoder model to map generated patents back to pixel space, which is crucial for generating high-quality video.
Use of Spacetime Latent Patches in Sora
Once the video has been compressed, Sora extracts a sequence of spacetime patches, which serve as transformer tokens for the model. This patch-based representation helps to produce videos of different resolutions and pixels. You can expect a similar workflow in image generation as well because an image is a form of a video.
Indeed, Open AI will not disclose details of Sora’s video generation process because it is their USP. I have read different expert reviews and also understood Open AI technical reports and articles before writing this process in easy words.
10 Capabilities of Open AI Sora
No doubt, it can be a revolution in the film industry as well. This powerful platform will help to create diverse and high-quality visual content even for Youtubers. However, you must understand the capabilities and limitations of Sora. Here are the ten capabilities that you can use for your video content, considering the privacy issues.
Image and Video Editing
OpenAI Sora offers image and video editing facilities. It can:
- Manipulate pre-existing images or videos.
- Create seamless loops
- Animate even still images
- Extend videos forward or backward in time.
These versatilities will open up a wide range of creative possibilities for us. This is just a beginning- think about what Sora can do after five or ten years!
Animating DALL·E Images
You can use Open AI DALL E for image generation, and Sora ‘breathes life’ into these images. You can create captivating videos. However, you can check the samples where you find lots of ‘illogical’ moves that suggest Sora is still in the early stages. Still, you cannot deny the ‘first look’ of Sora and how it captivates viewers with videos.
Extending Generated Videos
Sora not only creates videos from scratch, but it can go one step further – it extends existing videos with ‘artificial’ intelligence. If you are a video editor or filmmaker, you understand the importance of this feature. You can control the creation of infinite loops with text prompts.
Offers Video-to-Video Editing
It uses advanced diffusion models like SDEdit to edit videos based on text prompts. You can write a few text prompts based on your requirements and Sora will alter the styles and environments (on the video) to match the desired aesthetic. It helps to transform ordinary footage into cinematic reels with just a few simple commands.
Creates Connecting Videos
Sora also creates interpolating edits between two distinct videos, which offers smooth transitions. If you do not know about the edit history, then you cannot understand the difference. Sora does it so beautifully! Indeed, it enhances storytelling flexibility with continuity and coherence.
Use Sora for Image Generation
Do you know Sora generates high-quality images? It arranges patches of Gaussian noise to produce visually stunning images with resolutions of up to 2048×2048 pixels. As a content creator, you can use this tool for a variety of applications, from digital art to photography.
Emerging Simulation Capabilities
Indeed, Sora has been built to mimic the aspects of the physical world. It must follow all the scientific laws/logic of our world and apply them in the digital aspects. Sora is in the early stage, so you cannot expect ‘perfection’, but after years of training, it will mimic the real world better than what it is doing today.
3D Consistency and Dynamic Camera Motion
As a videographer, you know the importance of dynamic camera angles and motions. Now, you do not need to wait for the perfect shot; you can command Sora, and it will generate videos with dynamic camera motion. Moreover, it maintains consistency with the people and objects that move through three-dimensional space. This immersive feature enhances realism and adds depth to generated content.
Long-Range Coherence and Object Permanence
I know many of you have questions regarding this, but developers are working on maintaining consistency in long videos. However, Sora is good at accurately depicting people, animals, and objects over extended periods, even when they are leaving the frame.
Better Simulate Interaction of the Real World
Do you want a video of a painter painting strokes on a canvas or a slim girl eating a burger? You can expect better interaction and dynamic actions like the real world. It adds depth and enhances the aesthetics of the videos which means a better viewing experience.
Final Verdict
Indeed, OpenAI Sora represents a significant leap forward in AI-driven image and video generation. Its advanced capabilities help many videographers and filmmakers to find the right visuals easily. Sora offers a glimpse into the future of creative expression and digital storytelling. As AI technology continues to evolve, the possibilities for innovation and artistic exploration are virtually limitless with tools like Sora.
