• Abstract: Large-scale video generation models have the inherent ability to realistically model natural scenes. In this paper, we demonstrate that through a careful design of a generative video propagation framework, various video tasks can be addressed in a unified way by leveraging the generative power of such models. Specifically, our framework, GenProp, encodes the original video with a selective content encoder and propagates the changes made to the first frame using an image-to-video generation model. We propose a data generation scheme to cover multiple video tasks based on instance-level video segmentation datasets. Our model is trained by incorporating a mask prediction decoder head and optimizing a region-aware loss to aid the encoder to preserve the original content while the generation model propagates the modified region. This novel design opens up new possibilities: In editing scenarios, GenProp allows substantial changes to an object's shape; for insertion, the inserted objects can exhibit independent motion; for removal, GenProp effectively removes effects like shadows and reflections from the whole video; for tracking, GenProp is capable of tracking objects and their associated effects together. Experiment results demonstrate the leading performance of our model in various video tasks, and we further provide in-depth analyses of the proposed framework.

  We introduce VGMShield: a set of three straightforward but pioneering mitigations through the lifecycle of fake video generation. We first try to understand whether there is uniqueness in generated videos and whether we can differentiate them from real videos. Then, we investigate the textittracing problem, which maps a fake video back to a model that generates it.

  We present Patch-based Object-centric Video Transformer (POVT), a novel region-based video generation architecture. We build upon prior work in video prediction via an autoregressive transformer over the discrete latent space of compressed videos. Due to better compressibility of object-centric representations, we can improve training efficiency by allowing the model to only access object information for longer horizon temporal information.
