能力介紹

關于視頻超分辨的功能介紹以及具體調用參數說明，請參見視頻超分辨。

SDK包安裝

常見語言的SDK依賴包信息，請參見SDK總覽。

配置環境變量

配置環境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET。

重要

阿里云賬號AccessKey擁有所有API的訪問權限，建議您使用RAM用戶進行API訪問或日常運維，具體操作，請參見創建RAM用戶。
請不要將AccessKey ID和AccessKey Secret保存到工程代碼里，否則可能導致AccessKey泄露，威脅您賬號下所有資源的安全。

Linux和macOS系統配置方法
1. 在IntelliJ IDEA中打開終端Terminal。
2. 執行以下命令，配置環境變量。
  <access_key_id>需替換為您RAM用戶的AccessKey ID，<access_key_secret>替換為您RAM用戶的AccessKey Secret。如果后續需要進行更多權限相關的配置，具體操作請參見使用RAM Policy控制訪問權限。
```
export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id> 
export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>
```
Windows系統配置方法
新建環境變量文件，添加環境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并寫入已準備好的AccessKey ID和AccessKey Secret。然后重啟Windows系統。本操作以Windows 10為例進行說明。
1. 打開文件資源管理器，在此電腦上右鍵單擊屬性。
2. 在右側導航欄，單擊高級系統配置。
3. 在系統屬性對話框的高級頁簽下，單擊環境變量。
4. 在環境變量對話框中，單擊新建(W)。
5. 在彈出的新建系統變量對話框中，添加環境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并寫入已準備好的AccessKey ID和AccessKey Secret。
6. 重啟Windows系統，使配置生效。
