What is ConFiner
ConFiner is an innovative video generation framework jointly launched by multiple universities and research institutions. By combining multiple off-the-shelf diffusion model experts, it can generate high-quality and coherent video content without additional training. The framework decomposes the video generation task into three subtasks: structural control, spatial refinement, and temporal refinement. Each subtask is handled by a dedicated expert, improving generation efficiency and video quality. ConFiner introduces coordinated denoising technology and the ConFiner-Long framework, supports long video generation, and can produce coherent videos up to 600 frames, providing new creative possibilities for fields such as film production, animation creation, and video editing.
Main features of ConFiner
- Structural control: Responsible for generating the overall structure and plot of the video, providing the foundation for subsequent spatial and temporal refinement.
- Spatial refinement: Ensures that each frame has sufficient clarity and a high aesthetic score while maintaining coherence and consistency between frames.
- Temporal refinement: Further refines the temporal dimension of the video, enhancing its smoothness and dynamic effects.
- Coordinated denoising: A new denoising method that supports the simultaneous use of the knowledge of spatial and temporal experts during a single sampling process, improving the fineness and consistency of video generation.
- Long video generation: The ConFiner-Long framework can generate coherent videos up to 600 frames. Through clip consistency initialization, consistency guidance, and interleaved refinement strategies, it ensures smooth transitions and coherence between video clips.
Technical principles of ConFiner
- Innovative decoupling strategy: ConFiner decomposes the video generation task into three independent subtasks: structural control, spatial refinement, and temporal refinement. Each subtask is handled by a dedicated diffusion model expert. The experts have advantages in their respective fields, reducing the model's computational burden and improving the quality and speed of generation.
- Coordinated denoising technology: During video generation, ConFiner introduces a collaboration mechanism, using spatial and temporal experts with different noise schedulers to achieve gradual collaboration. This effectively improves the fineness and consistency of video generation.
- Breakthrough in long video generation: Building on ConFiner, the ConFiner-Long framework achieves high-quality, coherent long video generation through three strategies: clip consistency initialization, consistency guidance, and interleaved refinement. The ConFiner-Long framework can generate coherent videos up to 600 frames, advancing the development of long video generation technology.
- Control stage and refinement stage: In the control stage, ConFiner uses a highly controllable text-to-video model as the control expert to generate a video structure containing coarse spatial-temporal information. In the refinement stage, the spatial expert and temporal expert refine spatial and temporal details based on the video structure, using coordinated denoising to enable the two experts to work collaboratively under different noise schedulers.

Application scenarios of ConFiner
- Film production: ConFiner can generate visual sketches or special effects scenes for films, helping directors and production teams quickly preview and iterate on ideas, improving the efficiency of pre-production.
- Video editing: During video editing, ConFiner quickly generates video content, such as adding special effects or transitions, improving editing efficiency and enriching the final video effect.
- Animation Production: Animators use ConFiner to generate animation sequences, reducing creation time, especially when producing animation previews or proof of concept.
- Advertising Creation: The advertising industry uses ConFiner to generate attractive advertising videos, quickly transforming ideas into visual content, and attracting the audience's attention.
- Social Media Content Production: Social media users and content creators use ConFiner to produce high-quality video content for sharing on platforms, increasing interactivity and view rates.
