JoyAI-Video-Edit is a real-time, instruction-guided video editing system for open-ended video streams. Given a live camera stream or uploaded video and a natural-language edit instruction, it edits frames causally as they arrive, without waiting for the full video, requiring a predefined video length, or revisiting future frames. In our deployment benchmark, the full end-to-end pipeline reaches 30 FPS at 720 × 1248, pushing video editing from offline batch processing toward interactive streaming generation.

The system combines an MLLM-based condition encoder, a causal video VAE, and a 16B-parameter multimodal diffusion transformer. It is trained and deployed as an autoregressive diffusion editor, then accelerated with aligned autoregressive distribution matching distillation, long-horizon optimization, bounded KV-state inference, and deployment-oriented scheduling to sustain high-throughput 720p editing while reducing train-inference mismatch and accumulated temporal drift.

🔥🔥🔥 News!!

• 2026.08.15: 🎉 Live demo released — real-time streaming video editing on a single RTX PRO 6000 (Blackwell) GPU: 840 × 480 @ 24 FPS or 720p @ 16 FPS. Try HuggingFace Demo
• 2026.08.14: 🎉 Released an upgraded checkpoint with significantly stronger reference-image-guided video editing (RV2V), delivering better subject and identity preservation, more faithful reference conditioning, and improved temporal consistency across long streams. Grab the new DiT weights.
• 2026.08.05: 🎉 We release the deployment code, technical report, and JoyAI-Video-Edit checkpoints. Please check the links above for details.

💎 Highlights

• Real-time open-ended editing. Edits live or uploaded videos as frames arrive, without requiring the full sequence upfront.
• Diverse instruction control. Supports subject edits, local edits, background changes, style transfer, motion changes, and reference-guided editing.
• Autoregressive diffusion design. Combines an MLLM condition encoder, causal video VAE, and MMDiT backbone for streaming video editing.
• High-throughput 720p deployment. Reaches 30 FPS end-to-end throughput at 720 × 1248 with bounded KV-state inference and stable per-chunk compute.

🚧 TODO

• Stronger model version in progress. A more powerful version is under active development, with a particular focus on advancing reference-image-guided video editing (RV2V) capabilities.
• Consumer GPU support. Optimize deployment for consumer-grade GPUs such as GeForce RTX 5090.
• Diffusers support. Provide a 🤗 Diffusers pipeline for JoyAI-Video-Edit to streamline loading and inference.
• Release full training and data pipelines. Open-source the complete training framework and data generation pipeline.

🎬 Showcase

JoyAI-Video-Edit is designed for broad video editing tasks, including global appearance changes, local object edits, subject add/remove/replace, background replacement, style transfer, and reference-guided edits.
