5.3/ Dynamic Prompting: Interactively generate a story containing a sequence of events by modifying text prompts during generation. Here's a real-time demo of our UI.

5.2/ Streaming Video-to-Video Translation: Here's an example of transforming a Minecraft video into a realistic one (in real time!). In the future of gaming, maybe we could render only basic geometries, with AI video models adding all textures and lighting.

5/ Applications:
Thanks to causal dependencies, CausVid enables a wide range of additional applications without the need for fine-tuning!
5.1/ Image-to-Video: Treating an input image as the first generated frame, our method can naturally animate static images.

4/ CausVid can generate infinitely-long videos efficiently, by combining sliding window and KV-cache inference. Here we show that it produces long (30-second) videos with better quality than existing methods, while being orders of magnitude faster.

3/ Results:
⚡ 170x Faster (3.5 mins -> 1.3 sec latency)
⚡ 16x Higher throughput (0.6 -> 9.4 FPS)
🏅 Great quality (1st spot on VBench)!

2/ Our Solution:
We distill a multi-step, bidirectional video diffusion model into a few-step, causal model that generates video frames on-the-fly. Think of it like switching from downloading a whole movie to streaming it - you can start watching as soon as the first frame is ready.

1/ The Problem:
⏳ Current video diffusion models need several minutes to create just a 10-sec clip. Why so slow? A major issue is that these models can't show you anything until they've generated the entire video. Each frame is linked to both past and future frames through bidirectional attention.

🚀 Introducing CausVid: An autoregressive video generation model that starts playing instantly as you hit 'Generate,' while also securing the 1st spot on VBench!
