SmoothVideo: Smooth Video Synthesis with Noise Constraints on Diffusion Models for One-shot Video Tuning [PDF]
arXiv, 2023 Recent one-shot video tuning methods, which fine-tune the network on a specific video based on pre-trained text-to-image models (e.g., Stable Diffusion), are popular in the community because of the flexibility. However, these methods often produce videos marred by incoherence and inconsistency.

Composite Video Noise Modelling and Suppressing
Signal and Image Processing, 2011 In order to tackle the recording video denoising problem with non-stationary image contents, a critical task is to estimate statistical properties of the composite noise in video signals. After investigation of a variety of test video sequences, based on the wavelet decomposition of the noise, the estimation can be conducted by empirical modeling of ...

FreeNoise: Tuning-Free Longer Video Diffusion via Noise Rescheduling [PDF]
arXiv, 2023 With the availability of large-scale video datasets and the advances of diffusion models, text-driven video generation has achieved substantial progress. However, existing video generation models are typically trained on a limited number of frames, resulting in the inability to generate high-fidelity long videos during inference.

POS: A Prompts Optimization Suite for Augmenting Text-to-Video Generation [PDF]
arXiv, 2023 This paper targets to enhance the diffusion-based text-to-video generation by improving the two input prompts, including the noise and the text. Accommodated with this goal, we propose POS, a training-free Prompt Optimization Suite to boost text-to-video models.
