In this paper, we introduce a new task of zero-shot text-to-video generation and propose a low-cost approach (without any training or optimization) by leveraging the power of existing text-to-image synthesis methods (e.g., Stable Diffusion), making them suitable for the video domain.
Our key modifications include (i) enriching the latent codes of the generated frames with motion dynamics to keep the global scene and the background time consistent; and (ii) reprogramming frame-level self-attention using a new cross-frame attention of each frame on the first frame, to preserve the context, appearance, and identity of the foreground object.
Experiments show that this leads to low overhead, yet high-quality and remarkably consistent video generation. Moreover, our approach is not limited to text-to-video synthesis but is also applicable to other tasks such as conditional and content-specialized video generation, and Video Instruct-Pix2Pix, i.e., instruction-guided video editing.
As experiments show, our method performs comparably or sometimes better than recent approaches, despite not being trained on additional video data.</em>`,lt,$,xn='You can find additional information about Text-to-Video Zero on the <a href="https://text2video-zero.github.io/" rel="nofollow">project page</a>, <a href="https://arxiv.org/abs/2303.13439" rel="nofollow">paper</a>, and <a href="https://github.com/Picsart-AI-Research/Text2Video-Zero" rel="nofollow">original codebase</a>.',at,Q,it,z,rt,P,Zn="To generate a video from prompt, run the following python command",pt,S,dt,E,jn="You can change these parameters in the pipeline call:",ct,Y,Un='<li>Motion field strength (see the <a href="https://arxiv.org/abs/2303.13439" rel="nofollow">paper</a>, Sect. 3.3.1):<ul><li><code>motion_field_strength_x</code> and <code>motion_field_strength_y</code>.
