🍃 Brief Introduction
Please refer to the paper for details.
- We abstract the essence of video editing learning as the temporal maintaining of pixel-level editing effect, propose and model a temporal point-flow warped field to scalably generate video editing data in real time from image editing samples alone, demonstrate the effectiveness of this pixel-aligned paradigm towards learning video editing across diverse-level editing tasks, and reveal its promising extensibility to high-level video tasks such as segmentation-related tasks, low-level video tasks such as video deblurring, and controllable video generation such as condition maps to video.
- We posit that a model trained concurrently on both image and video modalities for generation and editing tasks should yield relatively aligned output distributions across the two modalities, as the image modality is essentially a special case of a video modality. Accordingly, we design a modality mimic generation loss and a modality mimic editing loss.
- The capacity for language-based visual editing fundamentally requires a model to comprehend the instruction and the reference visual inputs, localize the corresponding region in the reference visual input, and modify it exclusively. Rather than relying on fine-tuning additional modules such as VLMs with connector adaptation or assisted mask sequence inputs, we endow the model with this internalized ability through introducing sense-related tasks and corresponding editing-region-aware latent-level and attention-level losses.
- Viewed from the perspective of on-policy self-distillation (OPSD), the mimicry procedure underlying the modality mimicry paradigm, which we explored last April, essentially constitutes a form of OPSD for flow matching models. The editing and generation results of modality mimicry demonstrate that OPSD of flow matching models is indeed feasible. The mimicry methods described in this research—for instance, the modality mimic generation feature score loss or feature loss—can also be applied to the OPSD of image or video flow matching models, such as Z-image and Stable Diffusion 3.5 Medium.
🎞️ Video Editing Results
More results of various video editing tasks are demonstrated in the paper—all achieved by the same 1.3B model.
