# Subtitle Generator

A node that generates subtitles, using any input event with a ```Text``` attribute.
 
## Parameters
| <div style="width:170px">name</div> | description | <div style="width:120px">default</div> |
|---|---|---|
|Character Limit Per Line | The maximum number of characters that are visible in one line of the subtitle | 40 |
| Subtitle Display Buffer Time (Msec) | Buffer time increases the time subtitles are displayed on screen | 0 |
 
## Inputs
 
### Audio: 
&emsp;none 
 
### Events: 
| name | description | known nodes that generate this event |
|---|---|---|
| * | all events containing a 'Text' field | SR Http, SR WebSocket, Translate, ... |

 
## Outputs
 
### Audio: 
&emsp;none
 
### Events: 
| name | description |
|---|---|
| [Subtitle Generated](/v1/docs/events#subtitle-generated) | Contains the text, formatted into a subtitle file **.srt** format, in ```Data.Text``` field. |
 
## Remarks 
 
### Project Structure 

The node expects events that have the ```Text``` field. Which means the node can be used with any and all SR nodes. A minimum viable project that utilizes Subtitle Generator node can be built as such:

</center>

Taking this a step further, one can construct a project with Translator Node and Subtitle Generator Node to create subtitles in any desired language:

</center>
    
Another project that manipulates the SR output so that is translated, punctuated, filtered, normalized then formatted into a Subtitle Format.

:::(Warning) (Important Note)
Using Subtitle Generator with an [SR Http Node](/v1/docs/dataflow-nodes-speech-recognition-sr-http) that has the `Produce Recognized Words` parameter enabled results in significantly better and more in-sync results.
