StreamingT2V is an advanced autoregressive technique that enables the creation of long videos featuring rich motion dynamics without any stagnation. It ensures temporal consistency throughout the video, aligns closely with the descriptive text, and maintains high frame-level image quality. Our demonstrations include successful examples of videos up to 1200 frames, spanning 2 minutes, and can be extended for even longer durations. Importantly, the effectiveness of StreamingT2V is not limited by the specific Text2Video model used, indicating that improvements in base models could yield even higher-quality videos.

Caution: We would like the raise the awareness of users of this demo of its potential issues and concerns. Like previous large foundation models, StreamingT2V could be problematic in some cases, partially we use pretrained ModelScope, therefore StreamingT2V can Inherit Its Imperfections. So far, we keep all features available for research testing both to show the great potential of the StreamingT2V framework and to collect important feedback to improve the model in the future. We welcome researchers and users to report issues with the HuggingFace community discussion feature or email the authors.

Biases and content acknowledgement: Beware that StreamingT2V may output content that reinforces or exacerbates societal biases, as well as realistic faces, pornography, and violence. StreamingT2V in this demo is meant only for research purposes.
