Researchers have introduced EcoVideo, a novel framework designed to optimize video generation from Diffusion Transformer (DiT) models, particularly in cloud-edge environments. This system dynamically decouples frames based on their information density, estimated using self-attention entropy. High-entropy keyframes are processed by a cloud-based large model, while lower-entropy frames are reconstructed by a lightweight edge model through motion-aware interpolation. EcoVideo adapts its processing to available bandwidth and compute, achieving up to a 2.9x speedup in constrained edge settings while maintaining quality. AI
