I2VEdit is an innovative video editing technology that extends the editing of a single frame to the entire video through a pre-trained image-to-video model. This technology can adaptively maintain the visual and motion integrity of the source video and effectively handle global editing, local editing, and moderate shape changes, which existing methods cannot achieve. The core of I2VEdit includes two main processes: rough motion extraction and appearance refinement, which are precisely adjusted through coarse-grained attention matching. In addition, a skip interval strategy is introduced to mitigate the quality degradation in the automatic regression generation process of multiple video segments. Experimental results show that I2VEdit's superior performance in fine-grained video editing demonstrates its ability to produce high-quality, temporally consistent output.

TrailBlazer is suitable for a variety of user scenarios, providing an unlimited creative experience for video generation.

Traditional 3D content creation tools empower users with direct control over scene geometry, appearance, actions, and camera paths, transforming their imagination into reality. However, creating computer-generated videos remains a tedious manual process, which can be automated through emerging text-to-video diffusion models. Despite promising prospects, the lack of control in video diffusion models limits users' ability to apply their own creativity, rather than expanding it. To address this challenge, we propose a novel approach that combines the controllability of dynamic 3D meshes with the expressiveness and editability of emerging diffusion models. Our method takes animated low-fidelity rendering meshes as input and injectsground truth correspondences derived from the dynamic mesh into various stages of a pre-trained text-to-image generation model, resulting in high-quality, temporally consistent frames. We demonstrate our method on various examples, where actions are achieved through animating bound assets or altering camera paths.

SparseCtrl is developed to enhance the controllability of text-to-video generation. It enables flexible structural control by combining sparse signals with only one or a few inputs. It includes an additional conditional encoder to process these sparse signals without affecting the pre-trained text-to-video model. This method is compatible with various formats, including sketches, depth, and RGB images, providing more practical control for video generation and pushing applications like storyboarding, depth rendering, keyframe animation, and interpolation. Extensive experiments demonstrate SparseCtrl's generalization ability on both original and personalized text-to-video generators.

The Sieve Eye Contact Correction API is a fast and high-quality solution designed for developers, enabling eye contact correction in videos. This technology redirects eye gaze, allowing video subjects to simulate eye contact with the camera even when not directly facing it. It supports various customization options to fine-tune eye gaze redirection while preserving natural blinking and head movements, and introduces a random 'look away' feature to prevent a fixed gaze. Additionally, it offers split-screen views and visualization options for easy debugging and analysis. This API is primarily aimed at video creators, online education providers, and anyone looking to enhance video communication quality. The pricing is $0.10 per minute of video.
