+# ExVideo
+
+ExVideo is a post-tuning technique aimed at enhancing the capability of video generation models. We have extended CogVideoX-5B to generate videos up to 129 frames long. 
+
+This is our second publicly released model, incorporating LoRA into the structure of CogVideoX-5B.

+## Usages
+
+```python
+from diffsynth import ModelManager, CogVideoPipeline, save_video, download_models
+import torch
+
+
+download_models(["CogVideoX-5B", "ExVideo-CogVideoX-LoRA-129f-v1"])
+model_manager = ModelManager(torch_dtype=torch.bfloat16)
+model_manager.load_models([
+    "models/CogVideo/CogVideoX-5b/text_encoder",
+    "models/CogVideo/CogVideoX-5b/transformer",
+    "models/CogVideo/CogVideoX-5b/vae/diffusion_pytorch_model.safetensors",
+])
+model_manager.load_lora("models/lora/ExVideo-CogVideoX-LoRA-129f-v1.safetensors")
+pipe = CogVideoPipeline.from_model_manager(model_manager)
+
+torch.manual_seed(6)
+video = pipe(
+    prompt="an astronaut riding a horse on Mars.",
+    height=480, width=720, num_frames=129,
+    cfg_scale=7.0, num_inference_steps=100,
+)
+save_video(video, "video_with_lora.mp4", fps=8, quality=5)
