What is MobileVD?
MobileVD (Mobile Video Diffusion) is the first video diffusion model optimized for mobile devices, developed by the Qualcomm AI Research team. Based on the spatiotemporal UNet architecture of Stable Video Diffusion (SVD), the model significantly reduces memory and computational costs by lowering frame resolution, introducing multi-scale temporal representations, and employing two novel pruning schemes to reduce the number of channels and time blocks. MobileVD utilizes adversarial fine-tuning techniques to simplify the denoising process into a single step, further improving model efficiency.
Main functions of MobileVD
- Reduce frame resolutionThe resolution of the video frames was reduced from 1024×576 to 512×256, which reduced the amount of computation.
- Multiscale time representationIntroducing multi-scale temporal representation to better handle the temporal dynamics of video.
- Channel and time block pruningTwo novel pruning schemes were used to reduce the number of channels and time blocks in UNet.
- Counter-fine-tuningThe adversarial fine-tuning technique simplifies the denoising process into a single step, further improving the model's efficiency.
