MoViE: Mobile Diffusion for Video Editing
This enables practical mobile video editing, addressing deployment challenges for users on resource-constrained devices.
The paper tackles the problem of making diffusion-based video editing feasible on mobile devices by introducing a series of optimizations, achieving 12 frames per second while maintaining high quality.
Recent progress in diffusion-based video editing has shown remarkable potential for practical applications. However, these methods remain prohibitively expensive and challenging to deploy on mobile devices. In this study, we introduce a series of optimizations that render mobile video editing feasible. Building upon the existing image editing model, we first optimize its architecture and incorporate a lightweight autoencoder. Subsequently, we extend classifier-free guidance distillation to multiple modalities, resulting in a threefold on-device speedup. Finally, we reduce the number of sampling steps to one by introducing a novel adversarial distillation scheme which preserves the controllability of the editing process. Collectively, these optimizations enable video editing at 12 frames per second on mobile devices, while maintaining high quality.
