# Burning in timecodes on the video frames
<a name="timecode-burn-in"></a>

The **Timecode burn-in** setting determines whether a given output has visible timecodes inscribed into the video frames themselves. The timecodes are not an overlay, but rather a permanent part of the video frames.

**To burn in timecodes in an output (console)**

1. On the **Create job** page, in the **Job** pane on the left, choose an output.

1. Under **Stream settings**, **Preprocessors**, choose **Timecode burn-in**.

1. Optionally, provide values for the **Prefix**, **Font size**, and **Position** settings. Even if you don't provide these values, timecodes are burned into your output using these default values: 
   + **Prefix**: no prefix
   + **Font size**: **Extra Small (10)**
   + **Position**: **Top Center**

   For details about each of these settings, choose the **Info** link next to **Timecode burn-in**.
