We are excited to bring to you the incredible research paper from Victoria University of Wellington and NVIDIA on TrailBlazer: A Novel AI Approach to Simplify Video Synthesis Using Bounding Boxes. Advancements in generative models for text-to-image (T2I) have been remarkable, and researchers have now made significant strides in developing text-to-video (T2V) systems that can automatically generate videos based on textual prompts. However, one primary challenge in video synthesis is the extensive memory and training data required. To address the needs of casual users, researchers at NVIDIA research have now introduced a high-level interface for controlling object trajectories in synthesized videos that requires minimal code modifications and no additional training or finetuning.
By simply providing bounding boxes (bboxes) specifying the desired position of an object at several points in the video, together with the text prompt(s) describing the object at the corresponding times, users can modify the trajectory and basic behavior of the subject over time. This facilitates seamless integration of the resulting subject(s) into a specified environment, providing an accessible video storytelling tool for casual users.
The method proposed by the researchers requires no model finetuning, training, or online optimization, ensuring computational efficiency and an excellent user experience. Also, it produces natural outcomes, automatically incorporating desirable effects like perspective, accurate object motion, and interactions between objects and their environment. With this method, users can capture the desired motion of an animal or an expensive object without the need of sketching the desired movement on a frame-by-frame basis, thus saving time and effort.
The TrailBlazer approach is an incredibly exciting development in the field of video synthesis as it simplifies the process of creating videos with high-level control signals. It is a great example of how AI can provide accessible tools to enable users to create and tell stories with ease.
