Less is More: Data-Efficient Adaptation for Controllable Text-to-Video Generation

Figure 1. Our "Less is More" framework for data-efficient controllable generation. A T2V backbone, fine-tuned solely on a sparse, low-fidelity synthetic dataset (left), learns to generalize to complex physical controls. This enables precise, high-fidelity manipulation of shutter speed (motion blur), aperture (bokeh), and color temperature during real-world inference (right), driven by a continuous control.
