+# Video Recording Development
+
+## When to Use
+
+During video recording, audio and video signals are captured, encoded, and saved to files. You can specify parameters such as the encoding format, encapsulation format, and file path for video recording.

+
+## How to Develop
+
+For details about the APIs used for video recording, see [VideoRecorder in the Media API](../reference/apis/js-apis-media.md).
+
+### Full-Process Scenario
+
+The full video recording process includes creating an instance, setting recording parameters, recording video, pausing, resuming, and stopping recording, and releasing resources.
+
+```js
