DynamiCrafter
DynamiCrafter is an open-source image animation model developed by Tencent that brings still images to life by leveraging video diffusion priors to generate dynamic content with natural motion and temporal coherence. Released in October 2023, DynamiCrafter addresses open-domain image animation, where the model must infer plausible motion from a single static image without additional motion guidance. Built on a 1.4 billion parameter diffusion architecture, it utilizes a pre-trained video diffusion model as a motion prior, conditioning generation on the input image to produce animations maintaining the source's visual characteristics while introducing contextually appropriate temporal dynamics. The architecture combines image understanding with learned motion patterns, enabling animation of diverse content including landscapes with moving elements, portraits with subtle expressions, architectural scenes, and artistic compositions. DynamiCrafter demonstrates particular strength in generating physically plausible animations respecting spatial layout and depth relationships, avoiding warping distortions and unnatural deformations. The model supports multiple resolutions and varying animation lengths for different creative and commercial applications. Key use cases include animated photographs for social media, dynamic backgrounds for presentations, bringing artwork to life, and producing visual effects for creative projects. Available under the Apache 2.0 license, DynamiCrafter is accessible on Hugging Face, Replicate, and fal.ai, with community adoption through popular creative workflows. The model represents an important advancement in unsupervised image animation, offering a practical solution for content creators who need to add motion to static visual assets without manual animation skills.

About
DynamiCrafter is an image-to-video generation model developed by Tencent that uniquely combines image conditioning with text-guided motion control. Released in 2023, the model animates still images based on both the visual content of the input and additional text prompts that describe the desired motion, making it one of the first models to offer dual-conditioning for video generation. This innovative approach provides users with an unprecedented level of control over the animation process and has set a new standard in the image-to-video generation field.
The model architecture is built on a 1.4 billion parameter diffusion framework that incorporates both spatial and temporal attention layers for comprehensive video understanding. DynamiCrafter processes the input image through a visual encoder to extract appearance features, while simultaneously encoding the text prompt through a language model to capture motion intent. These two conditioning signals are fused within the diffusion process, allowing the model to generate videos that faithfully preserve the input image's visual characteristics while adding motion patterns described by the text. The cross-attention mechanism ensures effective fusion of information from both modalities, and this fusion quality is a fundamental determinant of the model's output performance.
DynamiCrafter's dual-conditioning approach addresses a fundamental limitation of pure image-to-video models, which must infer motion entirely from the static image without explicit direction from the user. By allowing users to specify motion through text (such as "camera pans left" or "wind blows through the trees"), DynamiCrafter provides significantly more control over the animation result. This makes it particularly useful for creative professionals who have a specific vision for how their images should be animated. The ability to direct the movement of specific elements within a scene represents a fundamental departure from traditional image-to-video models and significantly expands creative expression possibilities.
The model supports multiple resolution configurations: 256x256, 512x512, and 1024x1024 variants are available, and this variety provides flexibility for users with different hardware capacities. It has been evaluated on standard video generation benchmarks, demonstrating competitive performance in both visual quality and temporal coherence metrics against established alternatives. Its 1.4B parameter count keeps it relatively accessible from a hardware perspective, typically requiring 12-16GB VRAM for inference operations. The different resolution options allow users to select the most suitable configuration based on their hardware capacity and quality requirements.
During training, the model was trained on large-scale video-text pairs collected from diverse sources. The visual encoder and text encoder components are initialized from pre-trained models, leveraging transfer learning to significantly accelerate convergence during training. This strategy enables the model to develop strong generalization capabilities even with limited video training data. The quality of video-text pairings in the training dataset directly impacts the model's capacity to accurately interpret text prompts and translate them into appropriate motion.
DynamiCrafter is released under the Apache 2.0 license, enabling both research and commercial applications without restriction. The model has been integrated into various community workflows and serves as an important reference implementation for the dual-conditioning approach to video generation. Its codebase and pre-trained weights are available on GitHub and Hugging Face, and the model is actively used by researchers and developers worldwide for both academic research and practical applications.
