Mojito: Motion Trajectory and Intensity Control for Video Generation
This addresses the problem of controllable video generation for applications requiring realistic motion dynamics, though it appears incremental as it builds on existing diffusion models.
The paper tackles the challenge of integrating directional guidance and controllable motion intensity in video diffusion models, introducing Mojito which achieves precise trajectory and intensity control with high computational efficiency, generating motion patterns that closely match specified directions and intensities.
Recent advancements in diffusion models have shown great promise in producing high-quality video content. However, efficiently training video diffusion models capable of integrating directional guidance and controllable motion intensity remains a challenging and under-explored area. To tackle these challenges, this paper introduces Mojito, a diffusion model that incorporates both motion trajectory and intensity control for text-to-video generation. Specifically, Mojito features a Directional Motion Control (DMC) module that leverages cross-attention to efficiently direct the generated object's motion without training, alongside a Motion Intensity Modulator (MIM) that uses optical flow maps generated from videos to guide varying levels of motion intensity. Extensive experiments demonstrate Mojito's effectiveness in achieving precise trajectory and intensity control with high computational efficiency, generating motion patterns that closely match specified directions and intensities, providing realistic dynamics that align well with natural motion in real-world scenarios.
