 The video stream recorded by the Xiaomi Yi camera is **1920x1080 pixels** at a variable bitrate of **12.0 Mb/s**. Because we watch it on a simple TV set capable only of 1366x768 pixels, we we re-encode it with the following settings: The video stream recorded by the Xiaomi Yi camera is **1920x1080 pixels** at a variable bitrate of **12.0 Mb/s**.

 We can use **Avidemux** to make the final rendering (re-encoding). For a **comman line only** solution you can consider ffmpeg to perfomr the re-encoding and **mkvmerge** (contained into the **mkvtoolnix** Debian package) to merge all into a Matroska container. We can use **Avidemux** to make the final rendering (re-encoding).
