+# BasicVSR模型部署
+
+## 模型版本说明
+
+- [PaddleGAN develop](https://github.com/PaddlePaddle/PaddleGAN)
+
+## 支持模型列表
+
+目前FastDeploy支持如下模型的部署
+
+- [BasicVSR](https://github.com/PaddlePaddle/PaddleGAN/blob/develop/docs/zh_CN/tutorials/video_super_resolution.md)。
+
+
+## 导出部署模型
+
+在部署前，需要先将训练好的BasicVSR导出成部署模型，导出BasicVSR导出模型步骤，参考文档[导出模型](https://github.com/PaddlePaddle/PaddleGAN/blob/develop/docs/zh_CN/tutorials/video_super_resolution.md)。
