Instant iterative video edits
Hao AI Lab showed an iterative video workflow where you generate a clip and then apply natural-language tweaks like “Make it darker” or “Slow the camera,” producing revisions in roughly five seconds—an indication of ultra-fast creative iteration for previsualization and rough cuts. Fast, low-friction iterations like this blur the line between director notes and automated revisions. (x.com)
Hao AI Lab published a March 15, 2026 blog introducing "Dreamverse" and a workflow they call "vibe-directing," and the post lists core contributors Will Lin, Matthew Noto, Junda Su, Yechen Xu, and Peiyuan Zhang with Hao Zhang as corresponding author. (haoailab.com) The team reports that their FastVideo inference stack can produce a 5-second 1080p clip in approximately 4.55 seconds and contrasts that with other generators like Sora, which they say take 1–2 minutes per 5s clip, enabling the stitching of many short clips into a single 30-second scene. (haoailab.com) FastVideo's GitHub notes a March 13, 2026 live-demo release titled "Create a 5s 1080p Video in 4.5s with FastVideo on a Single GPU," shows ~608 commits, and lists the repository license as Apache-2.0 with roughly 3.2k stars. (github.com) The project attributes its speed-ups to algorithmic work including Sliding Tile Attention (STA) and sparse distillation techniques; the lab’s STA write-up frames prior DiT-based pipelines as taking minutes for a 5s clip and presents STA as a path to large inference reductions. (haoailab.com) FastVideo’s README and release notes list support for H100, A100, and consumer 4090 GPUs and claim end-to-end tooling for finetuning, LoRA, distillation, and an inference stack that targets cross-platform Linux/Windows/macOS deployment. (github.com) The blog and repo documentation explicitly name the UI and demo as "Dreamverse" and identify team roles including UI lead Tina Mai, tech leads Will Lin and Hao Zhang, and advisors Danyang Zhuo and Eric Xing, indicating an academic-lab led open-source development model.
