What is MobileVD
MobileVD (Mobile Video Diffusion) is the first video diffusion model optimized for mobile devices, developed by the Qualcomm AI Research team. The model is based on the spatiotemporal UNet architecture of Stable Video Diffusion (SVD). By reducing frame resolution, introducing multi-scale temporal representations, and adopting two novel pruning schemes to reduce the number of channels and temporal blocks, it significantly lowers memory and computational costs. MobileVD is based on adversarial fine-tuning techniques, simplifying the denoising process to a single step, further improving the model's efficiency.
Main features of MobileVD
- Reduced frame resolution: Reduces the resolution of video frames from 1024×576 to 512×256, lowering the computational load.
- Multi-scale temporal representation: Introduces multi-scale temporal representations to better handle the temporal dynamics of videos.
- Channel and temporal block pruning: Through two novel pruning schemes, reduces the number of channels and temporal blocks in the UNet.
- Adversarial fine-tuning: Adopts adversarial fine-tuning techniques to simplify the denoising process to a single step, further improving the model's efficiency.
