+## Supported Video Codecs
+
+Fishjam supports the following video codecs:
+
+- **H.264**
+- **VP8**
+
+## Default Codec
+
+Fishjam uses H.264 by default, however, to solve issue with Android emulators, VP8 is set when you're using Room Manager on Sandbox.
+
+### Changing the Codec
+
+Override the default codec by setting the `codec` parameter when [creating a room](/api/server/interfaces/RoomConfig#videocodec) using server SDKs.
+
+### Why VP8 and H.264?
+
+- **VP8**: A software-based codec supported across all devices, ensuring maximum compatibility. It's ideal for environments lacking hardware acceleration, such as Android emulators.
+- **H.264**: A hardware-accelerated codec offering superior performance. However, its availability varies by device, and it may not perform optimally at lower bitrates.
+
+For optimal performance and compatibility, assess your application's requirements and the environments in which it will operate when selecting a codec.
+We recommend using H.264 for production and VP8 for development as it works with Android emulators.
