What is VideoJam AI?
VideoJam AI is an innovative technology designed to improve motion generation in video models. It achieves this by combining appearance and motion data into a single unified representation. By integrating both elements, VideoJam AI enhances the accuracy and realism of generated videos, especially for tasks like video synthesis and editing. The model focuses on how things appear and how they move together to create more fluid and lifelike movements in video production.

How VideoJAM AI Works?
VideoJAM is a framework designed to enhance motion coherence in AI-generated videos by integrating motion directly into the video generation process.
Training Phase
During training, VideoJAM processes an input video and its corresponding motion representation. Both are noised and embedded into a single, joint latent representation using a linear layer. The diffusion model then processes this representation, and two linear projection layers predict both appearance and motion from it.
Inference Phase
During inference, VideoJAM introduces a mechanism called Inner-Guidance. This mechanism uses the model's own evolving motion prediction as a dynamic guidance signal to steer the generation toward coherent motion.
Notably, VideoJAM can be applied to any video model with minimal adaptations, requiring no modifications to the training data or scaling of the model.
