Recent advances in generative AI have significantly enhanced image and video
editing, particularly in the context of text prompt control. State-of-the-art
approaches predominantly rely on diffusion models to accomplish these tasks.
However, the computational demands of diffusion-based methods are substantial,
often necessitating large-scale paired datasets for training, and therefore
challenging the deployment in practical applications. This study addresses this
challenge by breaking down the text-based video editing process into two
separate stages. In the first stage, we leverage an existing text-to-image
diffusion model to simultaneously edit a few keyframes without additional
fine-tuning. In the second stage, we introduce an efficient model called
MaskINT, which is built on non-autoregressive masked generative transformers
and specializes in frame interpolation between the keyframes, benefiting from
structural guidance provided by intermediate frames. Our comprehensive set of
experiments illustrates the efficacy and efficiency of MaskINT when compared to
other diffusion-based methodologies. This research offers a practical solution
for text-based video editing and showcases the potential of non-autoregressive
masked generative transformers in this domain.
