Less is More: Data-Efficient Adaptation for Controllable Text-to-Video Generation
This paper introduces a data-efficient fine-tuning strategy for Text-to-Video (T2V) diffusion models, enabling new generative controls like shutter speed, aperture, and color temperature. The core finding is that fine-tuning on sparse, low-fidelity synthetic data yields superior results compared to photorealistic "real" data, by preventing catastrophic forgetting of the backbone model's priors. The proposed framework uses a joint training approach with a low-rank adapter (LoRA) to handle domain shift and a disentangled cross-attention adapter for physical effects. An evaluation methodology (FEP and SVP) quantifies backbone drift and semantic fidelity, demonstrating that simple synthetic data leads to cleaner adaptation and better generalization.
This research offers a paradigm shift for enterprises seeking to customize powerful generative AI models without prohibitive data acquisition costs. By demonstrating that "less is more" (simple synthetic data over complex real data) for fine-tuning, companies can rapidly deploy controllable T2V models for specific brand guidelines, creative content generation, or specialized visual effects. This significantly reduces the barrier to entry for advanced video synthesis capabilities, making personalized AI models more accessible and cost-effective for diverse business needs.
Key Findings Summary
Data Efficiency: Fine-tuning T2V models on sparse, low-fidelity synthetic data is superior to using photorealistic "real" data for learning new generative controls, preventing catastrophic forgetting.
Architectural Disentanglement: A joint training strategy with a backbone LoRA for domain shift and a cross-attention adapter for physical effects effectively isolates control signals.
Performance & Fidelity: Models trained on synthetic data maintain generative diversity and high semantic fidelity, enabling precise, high-fidelity control over physical camera parameters like motion blur, bokeh, and color temperature.
Robustness to Drift: The Fast Evaluation Protocol (FEP) and Slow Validation Protocol (SVP) quantify model drift, showing that synthetic data leads to minimal backbone corruption compared to real data.
Out-of-Range Extrapolation: The learned controls generalize plausibly beyond the training data range, demonstrating robust and continuous control.

Data Efficiency & Synthesis
This category explores the paper's core premise: using low-fidelity synthetic data for efficient model adaptation. It details the pyramid sampling strategy and scene content randomization, highlighting how simple, disentangled synthetic data prevents catastrophic forgetting and yields superior generalization compared to complex photorealistic data.
Model Architecture & Adaptation
This section focuses on the architectural innovations, specifically the joint training approach. It covers the backbone LoRA for domain shift absorption and the disentangled cross-attention module for injecting scalar physical parameters, explaining how these components work together to achieve precise and robust control while preserving the backbone's pre-trained priors.
Evaluation Methodology
Here, the paper's novel two-stage evaluation framework is discussed. The Fast Evaluation Protocol (FEP) provides lightweight metrics for monitoring backbone drift, while the Slow Validation Protocol (SVP) assesses final generative quality and temporal coherence. This framework quantifies semantic fidelity, video quality, and the "distributional drift rate" to diagnose and prevent backbone corruption.
Controllable Video Generation
This category showcases the practical application of the method, demonstrating fine-grained, continuous control over physical camera parameters such as shutter speed (motion blur), aperture (bokeh), and color temperature. It highlights the qualitative and quantitative superiority of the approach compared to text-based conditioning and data-heavy specialized methods, including its ability to extrapolate beyond training ranges.
